2012 Chevrolet Volt: Review notes




NEWS EDITOR GREG MIGLIORE: No range anxiety, just engine envy for me on this night as I shot out of the garage at One Autoweek Tower in the wake of a V8-powered Chevrolet Corvette, packing four more cylinders and gobs of power. But Chevy didn't launch the Volt to compete with its own supercar, and for what it is--an efficient, decent-looking sedan--the car measures up.
I've driven the Volt before. The interior has been an area I like, and it continued to resonate with me. I really enjoy the four-seat layout. It's to accommodate the T-shaped lithium-ion battery pack, but it looks sporty, offers plenty of room and makes for a nice atmosphere. Volt shooting brake, anyone?
I kid, but not entirely. The electronics, especially the touch controls on the instrument panel that work without buttons, are a cool feature, and much easier than MyFord Touch. The screen is clear and informative, and it tells the driver what is happening during braking and acceleration that's different in the Volt than a regular car. Props to Chevy for a sporty, dual-cockpit layout, too.
I am not exactly the Volt's target customer, (for a variety of reasons, actually, including my lust of horsepower), but I simply live too far away from our downtown Detroit office to truly make the most of the powertrain. I had a full charge indicated when I set out from work in the evening, and it was cashed before I finished my commute, which is about 27 miles to the suburbs. Obviously, that left nothing for the return trip in, and I had nowhere to charge it at my apartment complex.
Really, that's not a complaint; the car did what it was supposed to, though the mileage didn't quite measure up in brisk expressway driving--it's just the reality of my life circumstances right now. Conversely, if I could have charged it at home, it would have been nearly spot-on. As it is, it's nice only having to use gasoline some of the time.
Otherwise, the Volt drives fine. It's heavier than the Cruze and the Buick Verano, which share versions of this platform. Having driven both recently, the Volt feels almost like a paperweight. Despite the added girth, it's OK in corners and easily holds expressway lines through curves. Power from the 1.4-liter is decent, and I had little trouble defeating other cars as we jockeyed for lanes. It does help to know your vehicle and plan accordingly.
The big question is, will people pay for this technology? More than $43,000 is Cadillac and Corvette territory. Then again, remember how much the first iPods cost?
ASSOCIATE EDITOR JAKE LINGEMAN: This was also the first time I've been in the Volt for an extended period. I found it in the parking lot by one of the few outlets. It did give a nice spark when I unplugged it from the wall, but otherwise, easy as pie.
At first glance, the Volt looks almost like every sedan on the road. Only when you get closer can you see that the grille is blocked off and the shape is one big swoopy line. If you don't mind driving something that's a little quirky looking, you'll have no problem with the Volt.
It had 30 miles of electric range when I got in, and the odometer said 2,598.
This car is uneventful to drive, which is a good thing. Besides the lack of noise and the slower takeoff, it feels exactly like a regular car. But I suppose it helps that we're getting used to different forms of propulsion. I also feel as if I need to baby the hybrids a bit, even though this one warrants no range anxiety.
The interior looks well put together, especially at night when the center controls look black and glow greenish blue. It looks a bit worse during the day with the plain gray color. I do like the touch-sensitive controls though; they feel like those on an Apple iPod. The materials and seats are all upscale-looking, and the size is perfect for a family of four. It looked as if there was plenty of room in the back seat, even for adults.
It's funny that I didn't even notice the screen in place of the gauges. It almost feels natural now. It shows a big number for mph, and then around it is all the hybrid stuff such as how much battery you have left, what mpg you're getting, miles until empty, etc.
I drove it easily more than 30 miles, probably about 37, and I still had juice left in the battery. In my apartment complex, there weren't any plugs accessible, meaning that I couldn't charge it during my stint.
The Volt can really be your only car. No matter the range of all the plug-ins--if you ever want to go on vacation, or further than 50 miles, you need a gasoline engine. I live about seven miles from work, so 90 percent of the time, I wouldn't use a drop of gasoline. But, when the mood strikes, I could head out to the cottage, which is about 75 miles, if I needed to.
COPY EDITOR CYNTHIA L. OROSCO-WRIGHT: I was excited for my first drive in the 2012 Chevrolet Volt. Of course, you see more of them on the road now, which is good for Chevy and for the environment. And, one day in the not-too-distant future, most of us likely are going to be driving some type of hybrid vehicle, so we should get used to them. I could easily get used to driving the Volt.
The car looks good from the outside, not as futuristic as the concept but it has nice angles and curves. It sort of blends in with other four-doors yet stands out of the crowd just a bit. Inside, I like the layout of the cabin with the cockpit setup. And while I understand the four-seat setup because of the battery pack, you really wouldn't be able to seat more than two people in the back seat. No squeezing in a third person. So if you're considering buying this car, there's that to add to the list of things to consider. But the overall, layout is sporty and looks sharp.
The center stack is clean with the touch-pad buttons. Everything is clearly labeled and easy to use. I also like the digital display of the IP, which shows everything the driver needs to know about what's going on with the car's systems.
I live about 15 miles from the office, so I easily made the commute home and back to work (plugging in inside our garage overnight, of course) without using a drop of gasoline. And I still had a good amount of battery range left over. No, you're not going to blow anyone away from a stoplight in this car, but it has good power. My commute route only allows me to top out at about 50 mph, but the car was solid in passing, and the brakes were strong. The cabin stays quiet throughout the drive. My one nit is the A- and B-pillars, which are quite wide and can obstruct your peripheral vision.
With our work commutes, I could definitely see a Volt being a good vehicle for our household. Yes, it's a bit pricey, certainly more so than a Toyota Prius, but I like the Volt more than the Prius--the looks and the drive character. And you'd be saving gas money with either car. So the choice is yours. Me, I'd go with the Chevy.
SENIOR ART DIRECTOR TARA THEMM: This was also my maiden voyage in a Chevy Volt. Considering my 124-mile round trip to work, I knew I wouldn't completely benefit from the 30-mile range of the full battery charge. Obviously, the Volt wouldn't be a car fit for me because of the long commute, but it was still fun to bop around in for a weekend, with or without battery power.
If my husband didn't have our garage filled to the brim, I could have charged it. But there she sat for the weekend, without any electric juice to charge her up. While that left me slightly disappointed that I wouldn't experience the full effect of the Volt, that also leads me into one massive benefit, the 1.4 liter "backup" engine, or in my case, the main mode of transportation.
I am never able to take plug-ins home because of my long-distance haul, but the Volt allows a worry-free driving experience; no having a tow truck service on speed dial if you don't reach an outlet in time. You want to go for a spur-of-the-moment long weekend Up North? No problem. Don't have a place or time for a charge-up? Easy peasy. Just drive the darn thing, and, of course, make stops at the pump now and again.
My fuel economy averaged in the mid-30s when solely running on gasoline, but then it was a smidge above 90 mpg for a while after I ran out of battery power. For someone who doesn't have far to drive on a daily basis, the Volt is definitely a car to look into, if you can swing the $46,000 price tag for this specific build.
On the outside, the Volt carries an individual look that's borderline sporty. The pearlescent paint also gave the body lines a bit of extra dimension.
The interior was well done, and like most everyone else, I dug the touch-screen center stack. The one drawback is that while getting accustomed to control locations, I had to take my eyes off the road for some time to find my desired function since there wasn't anything distinct to feel for.
The all-digital dash was quite nice, too, and the designer in me appreciates the calculated font and graphic choices that are easy to read and intuitive to move through. However, I am still not sure about the accel/brake widget of sorts. What is that really telling me? Am I not already aware of what pedal my foot is on? The only time I was in the "leafy green zone" was when I was practically coasting. Duh.
While the Volt isn't for me, I would recommend others to try it on for size.

2012 Jeep Grand Cherokee SRT





Many a spring vacation starts and ends with a pile of overstuffed suitcases and backpacks crammed along with their respective owners into the family minivan, sedan or sport-utility vehicle. It's either for a round trip to the local airport or a long slog to and from a beach locale somewhere in the (hopefully) warmer and sunnier South.
Once at the destination, the vehicle—whether driven from home or rented on arrival—becomes an afterthought, an appliance that sits parked until the beer cooler or the SPF 50 runs low, or unless it's called upon for a run to a theme park or local entertainment establishment. Regardless, you've probably given much more thought to your destination than your choice of spring-break wheels.
We propose a compromise—try thinking of your motorized travel partner as an integral and equally important element of a successful spring trip. If sloth and gluttony are your goals, along with a substantial dose of sunshine and saltwater, pick from the plethora of utilitarian vehicles available. If economy is your primary driver, you, your tent and your hybrid will make out just fine. But if you choose a more active vacation—where quick bursts of speed, hard cornering and sudden stops are a big part of the postcard—only a proper performance vehicle will do.
For our spring snow-sports adventure to the mountains of Colorado, we knew we'd want a vehicle with utility to spare but also one with high-performance credentials—a vehicle as capable of hauling a load as it would be hustling from 0 to 60. Knowing that we'd be spending the week driving cross-country and then running through a gauntlet of twisty mountain roads, powering from peak to peak in search of white gold, we wanted a vehicle that promised solid SUV functionality and long-haul driveability, along with the kind of handling and performance we'd need in a high-altitude environment. From the very short list of high-performance sport-utility vehicles on the market (see sidebar), we chose the all-new 2012 Jeep Grand Cherokee SRT as a keen example of the segment. Did we mention that we needed to carry skis?
The 2012 Grand Cherokee SRT is the latest of the breed, built on the fourth-generation Grand Cherokee that debuted as a 2011 model (and promptly claimed our inaugural Autoweek Best of the Best/ Truck award). Our vehicle of choice came dressed to the nines in brilliant black crystal paint, with only the SRT badging, wicked blacked-out grille and dual-vent hood hinting at the monster hidden beneath. Our tester was accessorized by Mopar with a beefy Thule roof rack ($276) and ski/snowboard carrier ($172), and a Mopar-option, dealerinstalled Wi-Fi wireless kit ($508) tucked under the front passenger seat.
In SRT trim, Jeep upgrades the engine to a Godzilla-level 6.4-liter, 470-hp, 465-lb-ft V8, hooked to a paddle-shifted five-speed automatic transmission sending power to all four wheels via Jeep's Moab-tested Quadra-Trac four-wheel-drive system. The SRT powertrain massaging assured that the vehicle would easily hit our requirement for quickness: Chrysler says the Grand Cherokee SRT is its best-performing Jeep ever, running from 0 to 60 mph in 4.8 seconds and the quarter-mile in the 13s, with a top speed of 160 mph.
The Jeep's chassis also gets the SRT treatment that effectively turns the Grand Cher-okee from capable mountain goat into a taut and muscular mountain lion. At the center of it all is the SRT's Selec-Track system, which allows five settings (automatic, sport, tow, track and snow) for stability control, damping, transmission shifts, torque proportioning, throttle response and electronic limited-slip differential performance.
Special steering tuning and Bilstein adaptive damping provide a claimed 0.90 g of cornering force, while bright red Brembo calipers (six-piston fronts, four-piston rears) clamp 15-inch front and 13.8-inch rear vented rotors to bring the 5,150-pound SUV (6,500 pounds fully loaded) to a halt from 60 mph in just 116 feet. We ran on standard-issue Pirelli Scorpion Verde All-Season P295/45ZR 20-inch run-flat tires mounted on factory-forged aluminum wheels. Jeep recommends Pirelli P Zeros for maximum warm-weather grip, but we shied away from the three-season rubber in the hope of running into a spring snow squall.
The cabin of our machine came with standard SRT trim —deeply bolstered leather SRT seats with suede inserts, a heated, leather-wrapped, flat-bottomed steering wheel, carbon-fiber accent trim and plenty of space for four to spread out. We skipped the available rear-seat entertainment system and instead relied on the Wi-Fi system to keep laptops, game machines, phones and iPads wirelessly linked to the Inter-net and all the media options it has to offer. Multiple power ports (12-volt DC and 110-volt AC) kept everything running, while the built-in navigation system kept us on course.
Having traveled many miles with various forms of built-in or carried-on entertainment systems, it's safe to say that your money is best spent on Wi-Fi, even with a monthly cell-service fee.
Unlike factory entertainment systems that usually force everyone to watch the same programming, Wi-Fi lets each passenger choose how to while away the miles. Games, movies, social media, e-mail—everything you can access from your home or office is available while winging across the expanses of Nebraska at 80 mph. The hardship of long-distance travel melts into the background as miles fly by with nary a complaint. A bonus: Without the ceiling taken up by a TV screen, our SRT had a massive dual-pane sunroof that allowed us wide-open views skyward.
We were pleasantly surprised to see that the latest SRT comes with trailering capability, unlike the original, which took up the hitch zone with twin exhaust outlets. The 2012 model moves the tail-pipes, allowing Jeep to restore the hitch point—and gives the SRT up to 5,000 pounds of towing capacity. We didn't come close to that limit, but we did install a tailgate cargo rack that allowed us to punt some of the bulkier gear out of the cabin.
Though our 2,924-mile journey included mind-numbing hours of cross-country interstate travel, there were few complaints from passengers or pilots. For such a high-strung vehicle, the ride was smooth and steady, thanks in part to the settling effect of a full load.
The active cruise control garnered high praise, not only for keeping a steady pace but also for automatically slowing with fellow motorists when the inevitable state trooper appeared on the horizon.
Most surprising was the amount of time the big V8 spent in eco mode, with four cylinders deactivated. Chrysler says an improved active-valve exhaust system allows cylinder shutdown over a wider rpm range, upping fuel economy by as much as 13 percent and pushing range to 450 miles from the 24.6-gallon tank, or about 18 mpg. We never achieved that kind of mileage —our best average for a tank was 16.6 mpg (did we mention that we had skis on the roof?), while economy plummeted to 12.7 mpg in mountain driving. Overall, we posted 14.8 mpg, just bettering the EPA combined estimate of 14 mpg.
Automatic ride mode carried us across the Great Plains, but sport was our setting of choice in ski country, where it provided a just-right level of responsiveness without tacking all the way to track mode. Gear holding on grades via the steering-wheel-mounted paddle shifters was great, as was roadholding even when light snow and wet pavement loosened the traction. Braking was instant and linear, a critical commodity when corners come quickly and are at the bottom of steep downhill grades.
Though quick reflexes and surefooted handling are important in mountain driving, we gave our highest marks to the pure power we could summon from the big Hemi under the hood. In a region loaded with wheezing 18-wheelers, overloaded rental rigs and more four-cylinder Subarus than we've ever seen outside of Japan (or maybe Vermont), being able to obtain dragster-level thrust on demand is an attribute that cannot be underestimated. When that power comes on just as strong on a 6 percent grade at 10,000 feet as it does at sea level, it's nearly as joy-inducing as first tracks in knee-deep powder.
Spring trips always end too soon, but we didn't dread loading our bump-run battered bodies back aboard the SRT for the 1,200-mile ride home. With equipment loaded and locked, electronics running hot and the Grand Cherokee SRT ready to roll, what most would consider a brutal “are we there yet?” 24-hour trip back home beckoned us as just another chance to drive.
Can we go now?

2013 Cadillac SRX - Spy Shots


Cadillac crossover due a modest makeover.

By Nick Kurczewski / Photos by Chris Doane Automotive

General Motors and, in this particular case, its luxury-themedCadillac division appear to have finally cracked the code of keeping pace with the competition. The secret: subtle but continual improvements. The Cadillac SRX is already fresh from a round of mechanical enhancements that delivered more power and better economy, thanks to a 308-bhp V-6 engine and 6-speed automatic fitted with a fuel-saving Eco mode. For the 2013 model year, Cadillac is once again fine-tuning its sharply styled, 5-passenger crossover.


Change is More Than Skin Deep
Our spy photographers managed to capture the new SRX completely free of any camouflage. Okay, the front grille badge is covered, and there’s a thin strip of black tape parallel to one headlight. Use your imagination and look past this ‘trickery,’ and you’ll notice the brand new SRX doesn’t look all that different from the old one. The front grille has been slightly revised, as has the lower half of the front fascia. Overall, the sharp lines and creases carry on into the latest version – which is fine, since the SRX is already a handsome machine.

Bigger changes are planned inside, where the SRX will be fitted with a version of the capacitive-touch center stack used on the new XTS sedan. This large touch-screen display (12.3 in. with the XTS) minimizes distracting information when the driver has both hands on the wheel. Yet the system detects input via a dash-mounted camera, and responds to smaller gestures when additional info is needed (much like the interface you’d find on a smartphone). The system also features a wide range of voice controls and, according to GM, the software can be upgraded when needed.
Look for the 2013 Cadillac SRX to make an appearance at the upcoming New York Auto Show, which opens its doors to the media on April 4-5.




BMW i8 Coupe - Spy Shots


We get our best look yet at BMW’s high-performance plug-in hybrid.

By Nick Kurczewski / Photos by Brenda Priddy & Company

Little by little, the production version of the BMW i8 Coupe is coming more into focus, ahead of its launch in 2014. We’ve seen the car in concept form, most recently as a topless, 2-passenger model at the Beijing Auto Show. Prototypes spotted while undergoing road tests have looked strikingly similar to the concept that made its debut at the 2009 Frankfurt Auto Show, wearing the cumbersome BMW Concept Vision Efficient Dynamicslabel. We’ve even been provided with a sneak peek of the car via a former senior designer at BMWDesignWorksUSA.

Porsche Performance, Prius Economy.
This latest i8 Coupe prototype is sporting swirly blue and white paint, and some (temporary) clunky rear taillights that are probably there simply for safety regulations. As we’ve noted, the shape of this i8 is remarkably similar to that of the concept car. Look closely, and you’ll spot some tiny supports connecting the dramatic-looking dual rear wings to each rear fender. That’s an excellent indication the design detail is being readied for production. According to a source at BMW, the i8 Coupe will also retain the concept car’s forward-opening, gullwing-style doors.
Mounted at the front of the i8 is a 131-hp electric motor, while a 223-bhp turbocharged 1.5-liter 3-cylinder gasoline engine is positioned behind the cabin and drives the rear wheels. Capable of running solely on electric power for approximately 20 miles, the i8 Coupe is expected to return approximately something in the region of 70 mpg. BMW also estimates the i8 Coupe can sprint from 0 to 62 mph in less than 5.0 seconds—not too shabby for a fuel-sipper!
We’re still waiting for pricing information, though it seems a range of $150,000 to $200,000 is more than likely when the i8 Coupe goes on sale.

Bridgestone Air-Free Tire Concept


The airless tire with internal spokes made from recyclable thermoplastic resin.

By Tom Wilson

Like reaching the south pole or flying non-stop un-refueled around the world, a true run-flat tire seems an elusive last-great-goal to the world of wheeled transport.
Now Bridgestone has debuted a new concept tire towards that goal. Of course, in this age some sort of environmental tie-in is required with any advancement, and so Bridgestone is emphasizing the concept’s green qualities of reduced material and 100 percent recyclability. It’s part of a “cradle-to-cradle” recycling process, says Bridgestone.
Bridgestone’s non-pneumatic concept follows other pioneering efforts—Michelin has, er, aired similar concepts previously. But Bridgestone’s Air-Free Concept tire seems to have advanced the idea with recyclable thermoplastic resin construction of its many internal spokes. It’s these spokes that give the tire its shape, strength and flexibility, while a more conventional outer sheath of rubber provides a traditional tread surface.
Load capacity may be limited at the moment; the Air-Free Concept is rated for just 150 kg (330 lbs) according to non-Bridgestone sources.
We wonder just how much noise and wind resistance an open sidewall design such as the Air-Free Concept generates. While opening the tire’s internal construction to view makes sense in the education-oriented Air-Free Concept, practicality says the internal spoke construction will be sealed by a veneer of sidewall rubber should such a tire construction reach the mainstream. Bridgestone says it might be, but isn’t talking about a timetable yet.
Seems the idea might have serious consequences for the aftermarket wheel business too.

2013 Audi S7


More powerful answer to your five-door prayer


Looking at the Audi S7, we find it hard to believe hatchbacks ever went out of fashion. Few cars on the market have the presence of the A7 and its new high-performance derivative. While other manufacturers were busy building market-research-driven hatchbacks—vehicles like the BMW 5-series GT and Mercedes-Benz R-class—Audi simply tasked its designers with creating a beautiful five-door. The A7 doesn’t want for much, except perhaps more muscle than the 310 hp provided by its supercharged V-6.
Power to the Five-Door People
The S7 is powered by a 420-hp variation of the brand’s new twin-turbocharged 4.0-liter V-8. This engine, at the same output level, also motivates the new S6; it makes more power in the S8 and base Bentley Continental GT. There’s considerable commonality with the naturally aspirated 4.2-liter FSI V-8 still offered in other models, but the new engine features a number of enhancements, chief among them a pair of twin-scroll turbochargers and an indirect intercooler, all placed in the vee between the cylinder heads. The crankshaft design carries over from the 4.2 FSI, with reduced stroke; friction losses are significantly reduced. A cylinder-deactivation system—it closes the valves of cylinders 2, 3, 5, and 8 under light loads—helps fuel economy noticeably, especially when cruising in higher gears at constant speed. An engine stop-start system is standard.
