It’s not known if the leak was intentional or not, but the summary of a paper initially published by the Society of Automotive Engineers, since taken down from the SAE site, says that a new eight speed automatic transmission, given the designation 8L90 by General Motors, will be introduced in the 2015 Corvette, on sale next fall. The all-new 7th generation Corvette is currently offered with GM’s 6L80 six speed automatic and a seven speed manual gearbox. The 8L90 is described as being designed for rear-wheel-drive applications and variants will likely be used in GM’s fullsize pickups and in rear wheel drive Cadillacs.
The 8L90 has about the same overall dimensions as the 6L80, and is said to be able to handle up to 737 lb-ft of torque. It has a shorter first gear for better launch acceleration, an overall ratio spread of 7.0 and three speed sensors for better shift response. Other benefits are said to be better fuel economy, improved performance and a quieter car with improved NVH levels. (Read More…)
Just off the wires, we have word from Chevrolet that the 2015 Corvette Z06 will debut at NAIAS in January – the perfect time slot to steal some of the thunder from the Blue Oval, which will show the all-new Mustang and the F-150 to the public for the first time. Last year, Ford managed to upstage GM’s truck debuts with the surprise unveiling of the Atlas concept. Looks like GM is exacting some revenge.
Bob Lutz and his partners are taking Fisker Karmas, removing the extended range hybrid electric drivetrain, replacing it with the engine and transmission from a Corvette and calling the result the Destino. Now Quanta, an automotive supplier of gas tanks, radiators and fuel system parts, has gone in the other direction, integrating two 134 horsepower electric motors into the final drive of a C6 Corvette Z06 and showing the result at SEMA. Quanta is testing the waters for a possibly hybrid upgrade kit for the Corvette and other sports cars. The goal isn’t better fuel economy, but rather better performance. The Corvette QHP770 has a total power output of 770 horsepower, with an estimated 0-60 speed of 3.3 seconds and a hypothetical 11.3 seconds in the quarter mile. Total torque is claimed to by 1500 lb-ft. (Read More…)
Your humble E-I-C has already driven the new C7 in anger around a road course (of sorts), and I’ve also driven the current-gen GT500. The C7 is just brilliant, but at least four out of the five times I consider the issue I think I’d rather have the Mustang. Now we have the two cars going head-to-head where it really matters: the streets, yo. (Read More…)
The C4 Corvette is about the only Corvette that you can get for Camaro prices these days— even the 19-horsepower ’79s are worth good money now. Still, it’s pretty rare that I find a C4 at a cheap self-service wrecking yard; most of the examples I run across are melty-fiberglass burn victims, and the remainder have been picked clean. Here’s one of the latter type, discovered a few months back in Northern California. (Read More…)
General Motors announced that production of the 2014 Corvette Stingray Coupe has begun and that it has started shipping the all-new 7th generation Corvette to dealers from the Bowling Green, Kentucky facility where the sports cars are assembled.
In my role as Chief Justice of the 24 Hours of LeMons Supreme Court, prospective racers often ask me questions that go something like: “I have a (car type known to be fast and/or expensive) that I got for (credulity-strainingly cheap price) and I would like to race it in LeMons without getting hit with penalty laps. How can I do this?” In most cases, the car will turn out to be a BMW M3, Acura Integra GS-R, or C4 Corvette, and I tell the questioner to seek anothertype of car. Still, you can get genuinely horrible C4 Corvettes for LeMons-grade money, provided you sell off some trim parts and so on, and that’s just what happened with this bunch. No problem, I said, just drop in an engine that will anger the Corvette Jihad and all will be well (it helps that the Chief Perpetrator of LeMons racing was the owner and editor-in-chief of Corvette Magazine for years, and he can’t stand the Corvette Jihad). I suggested the Toyota 1UZ V8, as found in Lexus LS400s and SC400s, but perhaps there’s an engine that would raise the blood pressure of Corvette fanatics even higher. What engine would that be?

I’d be a day late and a dollar short if I cared about being professional automotive journalist. To wit, we recently discussed how the digitally rendered C7 Stingray droptop Vette’s 5-spoke wheels look like a last-minute “virtual” hackjob for a looming deadline. The nice folks at Corvetteblogger show otherwise during their visit to the New York Auto Show: these hoops made production spinning the wrong way.
With discretionary funds increasingly decreasing, low-cost (or make that “approachable”) cars are all the rage. Before the 2014 Corvette Stingray, the first new Corvette in nine years, is going on sale in summer, there already is talk of a little less expensive model. (Read More…)
This one’s for commenter LarryP2 whining about how we gave positive coverage to the Alfa 4C while apparently criticizing the C7 Corvette’s power output. As far as I can recall, nobody took issue with the LT1, just the godawful styling. Eat your heart out, Larry. Now I’m off to browse the classifieds for a nice C6 Z06.
General Motors’ powertrain engineers have undoubtedly demonstrated with the LS family of V8 engines that pushrods still have a place in the 21st century. As successful and popular as the LS has been, I don’t think it’s much of stretch to assume that the new LT1 V8 in the all new seventh generation Corvette will eventually replace the LS engine in its various permutations and applications. The LT1, still a cam in block engine, and still with Ed Cole’s 4.40 inch bore centers, adds direct injection to the Small Block Chevy heritage. The LS family has also been popular as crate motors, used by customizers and high performance enthusiasts as well as with a small industry of companies that specialize in high performance GM products. While you can buy a LS from General Motors with up to 638 horsepower, if that just doesn’t satisfy your need for speed, companies like Callaway, Lingenfelter and Hennessey have shown that the LS engine’s basic architecture is capable of putting out almost twice that power. After talking with Ken Lingenfelter about the new Corvette, I wonder, though, just how tuner-friendly the new LT1 will be. (Read More…)
It isn’t often one of the biggest news items coming out of NAIAS 2013 is from a tuning house … especially a tuning house nobody has ever heard of before. Attach the name Bob Lutz to a car, along with a brand new, fire breathing, tire shredding 6.2L LT1 V8 from the new Corvette, you are bound to turn some heads. Oh, and they wedged it into a Fisker Karma.
Chevy’s revived both the LT1 and the Stingray name for the C7 Vette. Apparently it’s got a better power/weight ratio than the Porsche 911 or Audi R8, though GM didn’t say what the car weighs. Personally, I think the C6 is gorgeous, so I’ll have to reserve judgement until I see this thing in the flesh tomorrow. Right now, I’m not so sure I’d take this one over a C6, crappy interior and all…
Among the key features:
-5 Driving modes including “Eco”
- A 7-speed manual with skip shift and active rev matching
There’s a new small block in town, baby: keeping the spirit of the original 1949 Kettering OHV V8 alive. Piston Slap says the new name is sad: mediocre memories of the Optispark munching, reverse flow coolin’ LT-1 is not a fitting successor to the sheer splendiferousness that was the LSX. Vellum Venom says that the 2006 Ford F-150 called, asking for its fender emblem back. But what’s the real story? (Read More…)
