Corvette Stingray with 455 HP-certified

At the beginning of this week, yesterday, to be more precise, Chevrolet has announced the fact that the engine powering the Corvette Stingray, the all-new LT1 6.2-liter V8 engine has been SAE-certified at 455 horsepower and 460 lb. ft. of torque which is quite impressive if you ask us. Thanks to the performance exhaust system these figures can be boosted to 460 horsepower and 465 lb. ft. of torque at 6.000 rpm and 4.600 rpm respectively. These two levels are both available for the convertible version of the Chevrolet Corvette Stingray and according to the manufacturer, these are the highest power ratings ever for an entry-level Corvette model, so it is something. In terms of fuel consumption, the new model is expected to exceed 26 mpg on the highway. The output mentioned earlier will engines the car to accelerate from 0 to 60 mph in less than 4.0 seconds according to the manufacturer. Of course, we do not know if these numbers are for the 455 hp models of if are for the 460 hp one.

The model can use 1 liter per 74 horsepower and so the LT1 has more power density than the LS3 of the C6, the 6.2-liter engine and more power density than the Z06-derived of the C6, the 7.0-liter LS7. Torque levels are comparable to the LS7, up to 4.700 rpm, but in the same time the higher torque is only 5 lb. ft. of torque lower than of the 7.0-liter engine. The new engine mentioned is capable of delivering 316 lb. ft. of torque from 1.000 rpm with 90 % of peak torque being available from 3.000 rpm to 5.500 rpm. This is actually very useful as it ensures better acceleration at all engine speeds. The engineers have offer advanced technologies including direct injection, an all-new combustion system and continuously variable valve timing.
