Chevy Reveals 2014 Corvette’s Next-Generation Smallblock V8

2013 Chevy CorvetteFor those readers who’ve been keen to learn more about the upcoming seventh-generation Corvette, Chevrolet has finally seen fit to blow the lid off of the engine that will be taking center stage in the all-new 2014 model: the generation five small-block V8. Outfitted with all the latest in advanced engine management technologies, the Gen 5, dubbed “LT1”, is set to be the flagship of Chevrolet performance engineering.

This baby is loaded with some serious tech, so let’s dive right in.

The all-new LT1 engine uses the same basic architecture of the original Small Block engine used on the 1955 ‘Vette. By maintaining a cam-in-block design as well as keeping the 4.40-inch bore center, the Gen 5 stands as something of an homage — but with a lot more power. With a massive compression ration of 11.5:1, the new LT1 and its 6.2L (376 cubic inches) of displacement generates a monstrous 335 kW (that’s 450 hp) and is estimated to produce no less than 450 lb-ft of torque. That’s a 20 hp and 26 lb-ft improvement over the outgoing LS3.

The extra power partly comes from an advanced direct injection fuel delivery system — the first of its kind ever used in a small block. To make room for the new system, spark plug angles were adjusted, the intake and exhaust valves were swapped, and new “multi-plane” pistons were developed to create a more complete combustion.

Thought the DI technology is just one of a long list of innovations: tri-lobe camshafts, PVC-integrated rocker covers, an all-new “E92” engine controller, as well as the integration of Active Fuel Management (AFM) systems make the new engine one seriously smart piece of equipment. In fact, Autoblog reports that the entire assembly and engine systems are so advanced that SAE International will be publishing a paper on Chevy’s advancements in the coming weeks.

Even forgetting that the new engine will put the 2014 Corvette Coupe ahead of big-time power cars like the Porsche 911 Carrera and the BMW M3, remember the LT1 most likely will be just one of several available powertrains, especially for the Corvette Z06. Either way it’s looking more and more like 2014 is going to be a special year for America’s favorite sports car.
