Tonawanda Engine also built the 6.2-liter LT1 V8 engine that powered the C7 Corvette Stingray, so this announcement continues the plant’s relation to the storied American nameplate.
GM president Mark Reuss paid a visit to the Tonawanda Engine plant today, located across the Niagara River in Buffalo, where he said that the plant’s employees’ experience building Small Block engines made it a perfect fit to build the high performance new LT2.
“The 2020 Stingray is Chevrolet’s first production mid-engine Corvette – the fastest, most powerful entry Corvette ever – offering new levels of performance, technology and craftsmanship,” Reuss said during his visit to the expansive 190 acre facility. “The Tonawanda team is up to the challenge to build this new LT2 engine at world-class quality levels that Corvette customers have come to expect.”
In addition to the LT2, Tonawanda is also responsible for building GM’s 2.5-liter LCV four-cylinder and 2.0-liter LSY/LTG turbocharged engines, the 4.3-liter LV3 V6, 5.3-liter L83 V8 and 6.6-liter L8T V8.
The LT2 engine boasts a stock output of 495 horsepower and 470 lb-ft of torque in the 2020 Corvette Stingray when equipped with the optional Performance Exhaust. Compared to the LT1 found in the previous generation Corvette, the LT2 has improved intake and exhaust manifold designs, a superior dry sump lubrication system and a different camshaft. The bore and stroke are the same at 6.2-liters, of course, and it also has the same 11:5:1 compression ratio.
The 2020 Corvette Stingray is produced exclusively at GM’s Bowling Green Assembly plant in Kentucky.
