Amazing The tuned C5 Chevy Corvette has 400 hp and reaches 40 MPG on the highway


This is a little known factoid for car fans who are not immersed in the Corvette world. America's sports car achieves surprisingly good fuel levels on the highway. A cautious right foot, riding back to the C4 Corvette with the six-speed manual gearbox and extending to the current seven-speed C7 shifter, saw that the mileage on the highway reached 30 mpg. LegitStreetCars on YouTube decided he could do better, and he did much better . In fact, he had an average of over 40 mpg on a recent road trip. This is the whole point of the video shown above.]

save on average over $ 3,400 a damn Corvette? The simple answer is: It's a world where gasoline is not as cheap as it used to be, and modern hybrid-powered supercars are very expensive. If it's possible to save money on the pump while still enjoying a throaty American V8, why not make the most of it? And the Corvette is a great platform for such an effort, as its manual transmission has a top gear that is overdriven for sluggish highway rides . The EPA rates a manual C7 Vette at 28 mpg highway, and C5 Corvettes like the 1999 model shown here deliver 26 mpg.

Getting 40 mpg from a 5.7-liter LS1 V8 requires more than just slow driving. However. As the video explains, this car has a special lean-burn engine sound that dilutes the air-fuel mixture at highway speeds of 50 to 75 miles per hour. To measure fuel consumption on the freeway, the car was refilled at a gas station near a Chicago motorway and driven to Wisconsin and back, where it was refilled a few hours later on the same pump.

The total distance was 314.6 miles the fuel pump, the car just took 7,813 gallons. By simple calculations, this equates to 40.2 miles per gallon of used gasoline, which is better than a slew of highly efficient hatchback and knockout doors on many electrified sedans like the Ford Fusion Hybrid. Not bad for a Corvette with 140,000 miles and a knocking V8, which transferred 364 hp to the wheels.

Why do not automakers do that? Running a lean engine can have negative consequences, including higher NOx emissions. Lean engines also run hotter, which can strain the components over time. It is not known if the lean constellation set for this Corvette is aggressive enough to dramatically influence these parameters, but we can not deny that it is indeed impressive to achieve 40 miles per hour in a high performance sports car.
