CHEVROLET NOTICIA CARRO DIA

It was the opportunity to drive yet another futuristic car, Chevrolet's Volt, this effort by General Motors a magnificent piece of work, especially its gas/electric powertrain.
Smooth as silk, so quiet Rolls-Royce has competition for their Ghost models, Volt could be a remarkable car which captures the attention of the American public; but getting people into Chevrolet showrooms is the real trick, isn't it? If they don't visit the dealer, they can't buy the car.
Volt won't go on-sale until November, 2010, but Sunday morning I drove the pre-production version of the car and spent well over an hour with Volt's Chief Engineer, Andrew Farah. Farah's been with the Volt almost since its inception.

We didn't learn too much more about the Volt that we didn't already know, but the chance to drive the real thing spoke much about the car.
So let's take a drive in a Chevy Volt....



Outside, it's a fairly conventional looking five-door hatchback. GM doesn't want to scare any potential buyers away by depending on only the wind tunnel for all the design touches. Design being purely subjective, and although the car expectedly doesn't look much like (or half as interesting as) the Volt concept, GM has hit what many might think a happy medium between too conservative and too far-out.
2009-11-30-_mg_0618.jpg Volt's 240-volt receptacle; there are also a 110-volt plug and a gasoline filler
There are three filler doors on Volt: one is for gasoline, one the receptacle for its 240-volt electric line (GM expects Volt buyers to install the charger at home) and there's a plug for a conventional 110 outlet.
The grille is mostly covered by plastic strips, and the engine/motor get their cooling air, like most modern cars, from under the car. Farah pointed out there are several "heat exchangers" (radiators) in the front of the engine compartment, including one each for the gasoline engine and electric motor, one for the air conditioning system, and more.
2009-11-30-File0019.jpg Volt's rear 3/4 view
Inside, the front seats offer pretty good legroom and headroom; the rear is a different story. While there's a nice amount of rear headroom, legroom is at a premium. I'm about 5'4" and wasn't comfortable in the Volt's rear seat.
Inside, there's more plastic than you can shake a swizzle stick at, but that's the kind of thing which could change before production begins. Unusual designs on the front door inserts are eye-catching but, frankly, a little weird. It's probably the most radical style touch on the car.
Unlike Nissan's Leaf, which has its batteries under the floor of the car giving passengers a flat floor, there's a high and wide center tunnel running between Volt's left- and right-side seats, front and rear, which is part of the battery system (which weighs about 400 pounds; Farah wouldn't give me a total Volt weight figure, but around 3,700 pounds wouldn't be far off).
2009-11-30-_mg_0750.jpg Instrument panel (computer screen, left) and center stack with nav, rear view and audio and HVAC monitoring and controls and shift lever
There's a computer screen instrument panel in front of the driver, a sophisticated unit which appears to be simple and easy to understand. The center stack contains another screen for the nav system (optional, as heated seats will be, too), rear camera and audio and HVAC status, plus controls for sound and interior air temperature.
Push the "start" button and Volt springs into life, though you might now know it because you won't hear or feel anything. A high-concept center shifter helps you pick your gear. All in all, it's an intuitive area for the driver, and GM drivers especially will feel right at home in Volt. It's a mix of old and new switchgear and screens.
The car is quiet, smooth and fast off the line (electric motors have all their torque at start-up, unlike gas engines which need time to build power). There's a bit more understeer (what racers call "push") than I would like; you except some push in any front-drive car or truck, but it's more pronounced in Volt. The most pronounced noise in the cabin was tire rumble. Farah said that he's not satisfied either, and GM is still working out a final choice for Volt's tires.
There's good driver visibility front, rear and to the sides. Getting in and out of the four-door is easy and naturally it has all the requisite airbags and other expected safety equipment. One more safety item: pull the turn signal lever and a horn gives two quick "toots" to warn pedestrians the car is around. By the time Volt gets to market, there will be a standardized, mandated sound for all "quiet" cars and I can't see the government (or the lawyers) allowing an active system rather than passive.
It goes, runs and stops, fitting most peoples' requirements for transportation.
2009-11-30-_mg_0814.jpg Yours truly, driving the Volt
Pre-production vehicles like I drove come after the concept and then the prototype stages; the car I drove might look a bit different inside and out when it does go on-sale. The powertrain and drive system, Andrew Farah told me, are pretty much set in stone and almost ready for the production versions. Farah told me that about 80 pre-production cars are being built for media evaluations, demonstrations for governments and utility companies and four of them will be the Volts you'll see at auto shows. Also, we ignore fit-and-finish in pre-production cars, so no comment on Volt's F&F inside and out; the final production cars are always better
The cars are built on a "test" assembly line in Hamtramck, MI, a line being developed as the cars are being put together during this pre-production period. This is how and when they learn to build the cars and shape the assembly line for the actual production cars.
I've driven almost all the gas/electric hybrids out there and even Honda's FCX Clarity hydrogen fuel cell sedan, and all of them are varying degrees of remarkable in their acceleration, interior quiet and, of course, high mileage.
2009-11-30-_mg_0596.jpg Andrew Farah, Volt's chief engineer, with his baby
In the hybrids we're used to seeing, the car runs mostly on the gasoline engine with assists from the electric motor; Volt turns this around by making the electric motor the only drive system. A 1.4 liter 4-cylinder gas engine, which has no connection to the front wheels, is used to keep the batteries charged during the drive. This also means if there is a major failure in the battery or electric drive system, the gasoline engine is useless for keeping the car moving. So you can theoretically be stranded in a four-cylinder gasoline engine car with a full tank of fuel.
What's the mileage with Volt? GM was ridiculed a few months ago for saying they expected 230 mpg with Volt. That's their story, and they seem to be sticking with it.
Andrew Farah told me, when I asked him two times during the day about the size of the gas tank, that "the fuel tank is large enough to produce a mileage figure of about 340 miles per fill-up". The 40 miles can be had on electric only, then the gas engine kicks-in to keep the batteries charged at a pre-set level so Volt's electric motor can continue to run.
He told me that the actual size of the gas tank, how many gallons it will hold, is still an in-house secret. However, announcements about Volt will be made at the Los Angeles Auto Show's media days this Wednesday and Thursday, and perhaps we'll find out the fuel tank size then.
That most-important announcement -- of pricing -- may or may not come this week. But Farah didn't flinch when I asked about the $40,000 figure which has been floating around for more than a year; he pointed-out that there is a $7,000 tax credit available, and with state and local incentives, pricing might drop below the low-$30's.
2009-11-30-_mg_0709.jpg Pre-production Volt being put through its paces in a Dodger Stadium parking lot
GM had set-up a coned-off "track", maybe ½-mile long, in a parking lot at Dodger Stadium, similar to the "race track" on the Jay Leno Show. On the Sunday after Thanksgiving, our Southern California weather was bright, clear and 76 degrees in downtown LA. GM certainly got the best possible showcase in terms of weather and the famed Dodger Stadium.
Interestingly, GM officials have generally referred to the Volt as an "extended-range hybrid" when the car was first announced. Now that's changed: it's being tagged as an "extended-range electric car". Trying to have the public think the Volt is all-electric, like Nissan's upcoming Leaf? Could be, but I don't think Volt should be referred to in any way as an EV; its on-board gasoline engine, albeit as small as it is, makes Volt a gas /electric hybrid (or maybe an electric/gas hybrid).
And they wouldn't let us take pictures of the engine compartment. Still not ready for its close-up; not yet as clean and tidy as GM would prefer
More in a future post this week after the Volt announcements at the LA Auto Show.
Now does it sound like the Volt is for you?

Gol GT é flagrado na fábrica da VolkswagenRead


 UPDATE: este Gol GT é uma versão vendida no México. Mas ao explicar sobre a existência de alguma versão do Gol chamada GT, a Volkswagen disse que o tal não existe. Não mencionou o modelo mexicano. Por isso a dúvida sobre uma possível versão GT nacional.

O blog UOL Carros publicou uma foto, feita por Eugênio Augusto Brito, de um Gol na linha de montagem da fábrica Anchieta, da Volkswagen, que fica em São Bernardo do Campo / SP, que nós aqui do NA já visitamos também. Mas veja o detalhe na tampa traseira do tal Gol. Um emblema GT.
Além disso, o Gol flagrado tem ponteira cromada no escapamento. Já por muito tempo se fala na imprensa automotiva sobre um possível Gol GTI da nova geração. Talvez o esportivo não irá se chamar GTI, e sim GT, para continuar na linha de esportivos que não são tão esportivos assim, como Golf GT e Polo GT.
Se esses modelos são chamados GT, porque o Gol deveria se chamar GTI? Ficaria uma diferença estranha. Bom, o Polo e o Golf nós sabemos que não são lá muito esportivos, pois tem um motor 2.0 igual ao motor de versões normais, entregando fracos 120 cavalos de potência.
Mas o que dizer do Gol GT? Será que ele terá uma potência ainda maior? Achamos difícil, pois Polo e Golf são modelos mais refinados e mais caros. Um Gol GT com mais de 120 cavalos de potência tiraria toda a graça de um Polo GT ou um Golf GT. Quem pagaria mais por um carro mais fraco?
Então o provável é que este Gol GT tenha o mesmo motor 2.0 de 120 cavalos dos outros dois. O que acha? Enquanto isso a Volkswagen continua a negar que existirá um Gol esportivo, ou um Gol GT.

Test Drive: 2010 Cadillac CTS Sport Wagon

When it comes to wagons, those made stateside have historically tended to be looked down upon, while those made in Europe are held in high regard. That may have something to do with the stereotype commonly held regarding domestic wagons: Many expect them to be large, lazy-handling beasts festooned with fake wood paneling — the kind driven by Clark Griswold in National Lampoon's Vacation. The 2010 Cadillac CTS Sport Wagon should help put that thinking to rest. With its rakish good looks and athletic personality, it's as far removed from the American wagons of yore as Brad Pitt is from Chevy Chase.
However, we would advise Griswold — or anybody considering the CTS Sport Wagon, for that matter — to skip the optional Performance package, since it includes a suspension so stiff it'd make an old Corvette proud. With that said, the CTS Sport Wagon offers all the goodness of the CTS sedan, including spirited performance, a handsome cabin packed with user-friendly luxury features and an overall size that's probably just right for most shoppers in this segment. And of course it has a far more generous cargo hold.
Still, a few of the 2010 Cadillac CTS Sport Wagon's rivals best it in a couple of respects. The BMW 535i xDrive wagon offers a more engaging driving experience, along with a more comfortable backseat. But this Bimmer only comes in all-wheel-drive form and lists for a couple grand more than the top-of-the-line CTS Premium AWD Sport Wagon. If we were considering a lower trim level of the Caddy wagon, we'd also look at the Audi A4 Avant, the BMW 328i wagon, and maybe even a sporty crossover, such as the Audi Q5 or Infiniti FX35.
So yes, we would cross-shop some European wagons, but the fact that the CTS can proudly hold its head up high in this group says something, something that couldn't be said way back when. If you'd like some brash yet classy American style in your sporty station wagon, then the CTS Sport Wagon will likely bring you as much joy as a trip to Wally World. When it's open, that is.

Performance
The Premium version of the CTS Sport Wagon comes equipped with the more powerful of the two V6 engines offered in the CTS lineup, that being the 3.6-liter V6 with 304 horsepower. The only transmission choice is the six-speed automatic — unlike the sedan, the wagon isn't available with a manual gearbox, though for most consumers we're sure this will be a non-issue. Taxed with hustling more than 2 tons of luxury wagon, the 3.6 provides fairly energetic performance, getting the CTS Sport Wagon to 60 mph in 7 seconds flat and through the quarter-mile in 15.1 seconds. Though generally quick, that time still lags that of some others in this segment. An Audi A4 Avant 2.0T, for example, can sprint to 60 mph in just 6.4 seconds and run down the quarter-mile in 14.6.
The CTS's transmission is what we call a tri-mode, offering automatic, sport automatic and manual-shift modes. In automatic mode it's a smooth operator that's reluctant to kick down a gear when you want more juice unless you give it the boot (ostensibly, its reluctance to downshift exists to optimize fuel economy). In Sport mode, it's too much the other way, downshifting eagerly but holding onto the lower gears too long. While running through a curvy mountain road, it resolutely remained in 2nd gear after we came out of the twisty section and onto a long straightaway, screaming along at high rpm when it could've upshifted to 3rd. Manual mode, worked via a pair of buttons on the backside of the steering wheel, was about average in operation, meaning it reacted fairly quickly to a downshift call, but had a noticeable delay when you hit the button to upshift.
Within the sport-sedan class, a stop from 60 mph in less than 120 feet is considered pretty good. This CTS wagon did the deed in 118 feet, an impressive performance given the wagon's 300 additional pounds of curb weight over the CTS sedan. There was no fade noted at the track during back-to-back panic stops, and the pedal provided an easily modulated, progressive action during normal driving.
We've raved about the previously tested CTS sedan's excellent ride and handling balance, and the same can be said of this wagon. Handling was hard to fault, with quick, precise steering (albeit without much road feel) and a flat, composed attitude through quick transitions.
Comfort
Well-bolstered and generously padded, the front seats of our test car provided comfort on longer trips and support during aggressive cornering. The power tilt-and-telescoping steering wheel's generous range of adjustment allowed each of our staffers — who range in height from about 5-feet-1 to more than 6 feet — to find an ideal driving position. Both the seat heaters and coolers were powerful, warming us up quickly on chilly mornings and preventing sweaty-back syndrome while driving home on sunny afternoons.
In back, it's another story. The rear seat may look inviting, and for smaller folks it's fine. But bigger staffers (5-feet-10 and up) complained that although legroom is ample, the short seat cushion and aggressive outboard side bolsters made for a somewhat pinched, uncomfortable perch.
Equipped with the optional Performance package that includes a firmer suspension, our test car's ride was just too darn stiff. Around town, when bombarded with broken pavement and potholes, the CTS Sport Wagon gave us a bumpy ride that was seriously out of character for a car wearing the wreath and crest. Though this package also includes some enticing features such as xenon headlights and 19-inch alloy wheels (versus the standard 18s), we'd suggest skipping it and enjoying a more supple ride along with still-respectable handling capability.
Function
For a car fitted with so many luxury features (navigation system, seat heaters/coolers, dual-zone automatic climate control), the CTS Sport Wagon is easy to acclimate to. The audio system features a pair of tried-and-true knobs for power/volume and tuning, while the individual temperature controls are angled toward the driver and passenger. An analog clock sits up high, and even though the center stack has various like-shaped buttons, they are grouped logically. The nav system is simple to use and also features traffic reporting along with rerouting options. The cheeky rear roof pillars hinder vision to the rear quarters, but the Premium comes with a reverse park-assist system and a back-up camera that make parking a snap.
With the rear seats up, the Sport Wagon provides 25 cubic feet of cargo space — that's more than an A4 Avant and about the same as an FX35. Flip them down and you'll have 58 cubes, which is 7 cubes more than you'll find in the A4 and 4 cubes shy of the FX35's maximum. Notably, the cargo floor is dead flat when the seats are down and features adjustable tie-downs on either side.
Design/Fit and Finish
The Sport Wagon mostly boasts the same clean, chiseled lines as the sedan, and even with the wagon roof line still manages to have a jaunty, sporty presence. Though the rearmost side window is canted aggressively, the trailing edge of the roof line is more vertical, which optimizes cargo room. The stacked headlights and large egg-crate grille — both part of Caddy's newest design language — work well here, and the car's proportions are spot-on. Somehow the CTS Sport Wagon manages to look lower and sleeker than an equally long but taller crossover, while providing nearly identical passenger and cargo space.
The cabin design is likewise a feather in the CTS's cap, an interesting mix of textures and shapes arranged in a cohesive manner. The materials are mostly quality pieces, with just a few minor missteps. Lustrous wood accents abound, and nearly the whole dash top is covered in handsomely stitched, soft-touch vinyl, though the hood over the instruments is hard plastic. Overall fit and finish is very good.
Who Should Consider This Vehicle
If you're a casual driving enthusiast who wants a wagon with a decidedly new-age Cadillac flavor — that is to say not subtle yet not overdone — the CTS Sport Wagon should offer strong appeal. If you demand a more involving drive from your set of wheels, then we'd strongly suggest back-to-back test-drives with the rivals mentioned earlier.
