Chevy SS prototype spotted wearing Pontiac G8 clothes

Do not adjust your computer screen, you are not seeing the rebirth of the Pontiac brand. General Motors has chosen to use a G8 to disguise a test mule for the latest prototype of the forthcoming Chevrolet SS. The G8 was closely related to the Holden Commodore and Vauxhall VXR, the platform upon which the new Chevrolet performance model will be based. It should come as little surprise, then, that GM has opted to use the cladding from the former G8.
Thought the front clip of this mule is pure Pontiac, note the vents immediately behind the front wheel. That is a distinctive design hallmark of the Vauxhall VXR. Also note that this vehicle is right-hand drive, as the Holden and its Chevy counterpart will be very closely related. That likely includes potential drivetrains. The spy photos of this mule also reveal very wide rear tires, and rear wheels that do not match the fronts.

Can Fernando Alonso win Indy? Here's why and why maybe not

SPEEDWAY, IN – The month of May has been a joy ride for Fernando Alonso at Indianapolis Motor Speedway. The two-time Formula 1 champion came to Indy having never turned left in a race car without also turning right. But he acquired such a feel for Indy's 2 1/2 -mile rectangle during a month of practice and qualifying that he's considered a strong contender to win the 101st Indianapolis 500 on Sunday, rookie or not. "You're not trying to bring somebody on who has very little experience driving very high-performance cars," said 2003 Indy 500 winner Gil deFerran, who this month has helped Alonso learn the nuances that make the speedway such a tough place to conquer. "I suppose it would be a little bit different if you were dealing with a younger, much less experienced person." Driving a McLaren Honda from the potent Andretti Autosport team, Alonso was consistently near the top of the speed charts in practice, he qualified fifth fastest at 231.300 mph, and he handled runs in heavy traffic like a driver who'd done it many times before. But those were the prelims. The race is another creature. "The car felt the best (it has) in the last two weeks. I was making some moves, taking some different lines. I am extremely happy." Other drivers say the speedway looks different on race day when the crowd, expected to top 300,000, fills the grandstands and makes an already narrow track seem even tighter. The three-wide rolling start is something Alonso has never experienced, and he will see the green flag from the middle of the second row between Takuma Sato and J.R. Hildebrand. And the space he'll be given by his competitors in the first 180 laps may disappear In the last 20 when it's every driver for themselves. Can a rookie like Alonso win this race? Absolutely, as Andretti driver Alexander Rossi showed last year when his team used a fuel-mileage strategy to win in his first taste of Indy. We're talking about Fernando Alonso here, who easily could show his rookie stripes to the rest of the field most of the day. His best lap in Friday's final practice, 226.608, was fifth fastest in the field and, more important, he said the car felt comfortable in heavy traffic. "The car felt the best (it has) in the last two weeks," Alonso said. "I was making some moves, taking some different lines.

Why an independent rear suspension for GM's new, full-sized SUVs wasn't easy

A Motor Trend report last month laid out how Cadillac's 4.2-lier twin-turbo Blackwing V8 could be an orphan due to cost concerns in the GM empire. Last-minute chassis changes to Cadillac's new sedans and XT6 crossover led to engine bays that couldn't fit the Blackwing. On the SUV side, according to the report, the new independent rear suspension for big people haulers cost so much to implement that GM ruled out reworking the Escalade to accept the Blackwing. At least one commenter rightly asked how could a suspension swallow that much money. A new piece in Motor Trend has the answer. The excellent Alissa Priddle spoke to Tim Herrick, GM's executive chief engineer for full-size trucks, about why the clean-sheet IRS cost "multimillions of dollars."  First, GM would need to build a new body shop at the Arlington, Texas plant that assembles the automaker's big SUVs to stamp the numerous wholly new parts and panels accommodating an IRS. Then GM would need to design and pay for a new assembly process. On top of those up-front costs, there was the incremental cost of the four-link IRS components being more expensive than those in the trucks' former leaf-sprung solid axles. Herrick endured so many rejections for so long that he remembers the date and time when he got approval for the new unit. He said it came down to a meeting where he told a higher-up, "I'll make you a deal: If we get to the reveal, or if we launch this and you think this was a dumb idea, I'll hand you my badge and let you walk me out." Head to Motor Trend to read the full story. Based on Herrick being on stage to help present the new SUVs to the press, and on our First Ride in the new Chevrolet Tahoe and Suburban at GM's Milford Proving Grounds, it appears this will have a happy ending for all involved. Furthermore, since Herrick worked on the T1 platform that supports the big SUVs as well as the light- and heavy-duty pickups, he understood the demands on the commercial side, too. That could be why when Roadshow asked Tim Asoklis, chief engineer of the Tahoe and Suburban, if the new IRS could endure life in the Chevrolet Silverado and GMC Sierra, Asoklis answered, "Oh, absolutely."
