Power Machine: A Peek Into GM’s Newest Corvette
General Motors (NYSE:GM) has officially pulled the file containing the performance statistics for the C7 Corvette Stingray — and needless to say, it looks like the latest addition to the Corvette family has the means to take its rightful place among the annals of the legendary nameplate.
The 6.2 litre LT1 V8 will be good for 460 horsepower at 6,000 rpm, with an equally enticing 465 lb-ft. of torque to help move the car from 0 to 60 in the sub-four second timeframe. Most of the torque — up to 316 lb-ft of it — is available from just 1,000 rpm. With the pedal to the metal, the torque figure will fall only 5 lb-ft shy of the outgoing 7.0 litre LS7 V8, seen in the last Corvette Z06.
When the standard exhaust is plugged in, the figures will fall by 5 units respectively, to 455 horsepower and 460 lb-ft. However, the power offered was not created entirely at the detriment of efficiency; GM says that the LT1 will also be the most efficient LT1 yet, as it uses Active Fuel Management, direct injection, and variable valve timing help cut emissions by about 25 percent.
Other engineering goodies include four-into-one exhaust manifolds, a new intake manifold design, and an oil system with piston squirters to keep the cylinders cool when the car is being thrashed around as it’s meant to be.
“The 2014 Corvette Stingray’s LT1 engine is a triumph of advanced technology, delivering more power and torque than ever before with greater efficiency,” said Jordan Lee, Small Block chief engineer, in the company’s press release.
“The LT1′s performance complements the Corvette’s low mass with a tremendous feeling of power that builds as the rpm climbs. Drivers will experience more power and acceleration than ever before with the standard engine – in fact, its power and torque surpass many uplevel engines offered by competitors.”
The LT1 will be matched against Ford’s (NYSE:F) 5.0 litre V8 found in the Mustang GT, which is good for 420 horsepower and 390 lb-ft of torque. Though Ford also offers the 5.8 litre supercharged monstrosity found in the Shelby Mustang, good for 662 horsepower, it will likely only be a matter of time before the LT1 is tweaked and bumped to push out comparable numbers.
As V10′s and V12′s continue to be phased out in favor of lower cylinder count engines for efficiency reasons, V8′s are finding themselves at the hearts of some of the world’s most powerful and blisteringly quick cars. Sweden’s Koenigsegg Agera R, which puts out over 1,100 horsepower on E85 fuel, is powered by a 5.0 litre V8 — albeit heavily modified. Koenigsegg’s previous engine, the 4.7 litre V8, was provided courtesy of Ford. One thing is certain — when the successor to the Z06 is released, the engineers at GM have quite the platform to build off.
Investors have been optimistic in 2013 as shares of General Motors are up over 16% this year:
