Yesterday we brought you the news that General Motors had unveiled the new LT1 small block V8 that will serve as the powerplant of the upcoming “C7” 2014 Chevrolet Corvette and today, we take a look at the specifics of that new engine – beginning with the fact that the C7 Corvette will offer at least 450 horsepower and 27 miles per gallon.

We have known for some time that the seventh generation (C7) Chevrolet Corvette would feature an all new V8 engine when it arrives for the 2014 model year but rumors suggested that the new Corvette engine would be smaller in displacement (5.5 liters) possibly with forced induction (twin turbocharging). However, the new LT1 V8 sports the same 6.2 liters as the 2013 Chevrolet Corvette base engine while making more power and achieving better fuel economy than the current LS3 V8.

The new LT1 V8 engine that will power the 2014 Chevrolet Corvette ushers in the 5th generation of the fabled GM small block and with this new engine lineup comes more technology than has ever been utilized on a GM V8 – which GM claims will help the C7 Corvette offer at least 450 horsepower, 450lb-ft of torque and 27 miles per gallon. For comparison, the base 2013 Corvette (C6) offers 430 horsepower and 424lb-ft of torque while reaching 26 miles per gallon so the 2014 Corvette will pack so the next generation Corvette and LT1 V8 engine will make about 5% more power while also being more fuel friendly. Granted, these figures for the new 2014 Corvette engine are preliminary and actual production numbers could vary but we can fully expect that the C7 Corvette will have more horsepower, more torque and better fuel economy than the C6 Corvette.

General Motors has stated that the “entry level” 2014 Chevrolet Corvette will dash from 0-60 in under 4 seconds. That is incredibly impressive considering that the 505 horsepower Corvette Z06 (C6) moves out from nil to 60 in 3.8 seconds.

The rumors surrounding the 2014 Chevrolet Corvette V8 engine suggested that GM would go to a smaller 5.5L engine with twin turbocharging to help allow the C7 Corvette offer better fuel economy. This would allow the Corvette to have less negative impact on the automaker’s overall fleet fuel economy figures that will have to meet the government’s strict CAFÉ laws. Instead, the new LT1 V8 engine features a larger 6.2 liters of displacement fitted with plenty of high tech engine controls to improve the fuel economy of this powerful engine.

“Our objective for the development of the all-new LT1 was to raise the bar for performance car engines,” said Mary Barra, senior vice president, global product development. “We feel that we have achieved that by delivering a true technological masterpiece that seamlessly integrates a suite of advanced technologies that can only be found on a handful of engines in the world. What makes this engine truly special is the advanced combustion system that extracts the full potential of these technologies. The art and science behind that combustion system make the Corvette LT1 one of the most advanced V-8 engines in the world,” said Barra.
