Tuning company ZZPerformance has managed to squeeze huge power numbers out of the tiny turbocharged 2.0L engine (production code LTG) that was offered in the Cadillac ATS.
In a video posted to its YouTube channel recently, ZZPerformance’s heavily modified Cadillac ATS is seen putting down an impressive 511 horsepower and 493 pound-feet of torque directly to its rear wheels. The shop claims the car is now the world’s only 2.0L powered Cadillac ATS with more than 500 horsepower on tap – an impressive feat for a relatively small Grand Rapid, Michigan based company. Crucially, the car in question also has a six-speed manual transmission, adding to the fun-to-drive nature of this wildly powerful luxury sedan.
ZZPerformance’s ATS is now even more powerful than the performance-focused Cadillac ATS-V. The ATS-V featured a twin-turbocharged 3.6L V6 engine (production code LF4) that was good for 464 horsepower and 445 pound-feet of torque. The ATS-V was also offered with a six-speed manual transmission, though Cadillac’s eight-speed automatic transmission was available for a small price premium.
ZZPerformance offers a wide range of aftermarket performance parts for Cadillac’s turbocharged 2.0L four-cylinder engine. This particular car has a ZZP-engineered turbocharger, which helps to provide a huge 25 psi of boost, along with an E85 ethanol conversion kit and a special ZZP ECU tune. Other 2.0L engine parts the company offers include a performance camshaft, a throttle body spacer, valve springs, forged pistons and connecting rods and a cold air intake, among more. Due to this abundance of available parts, we wouldn’t be shocked if ZZPerformance was capable of building a 2.0L-powered ATS with even more power than this. Perhaps we’ll see that sometime in the future?
