As development of the 2013 Cadillac ATS is nearing completion and a Detroit Auto Show debut is just weeks away, more information is beginning to come to light.
GM just broke news of the ATS powertrain lineup, which includes a new-generation 2-liter turbocharged (2.0T) Ecotec four that produces 270 horsepower and will debut in the new entry-level Caddy when it hits the market next fall. Also available will be a new 2.5-liter inline four-cylinder and a 3.6-liter V6, with all three engines expected to be offered with either manual or automatic transmissions.
In an advance presentation to the press this afternoon, GM officials said that the new 2.0T four, which be built at Spring Hill, Tennessee, will make its debut in the 2013 Cadillac ATS and will produce 270 horsepower. That’s more horsepower per liter than the BMW M3, Porsche 911 Carrera GTS or Lamborghini Aventador.
With a new twin-scroll turbocharger delivering up to 20 psi of boost, the new 2.0T should also be a step more responsive that GM’s current generation of turbocharged engines. What’s more impressive is that the engine makes 90 percent of its peak torque from 1500 to 5800 rpm. Those changes add hope that GM's new performance engine will have the sort of robustness and responsiveness of BMW's turbocharged fours and sixes.
According to GM powertrain officials, the new 2.0T is over 95-percent new compared with the 2.0T engine currently used in the 2012 Buick Regal GS. Breathing has been completely redesigned – it’s in the opposite direction of the current engine compared to the current 2.0T – and it’s been designed to be easily adaptable to both transverse and longitudinal applications.
Bore spacing is the same as the current engine (86X86, but it’s physically several inches shorter thanks in part to a new modular balance-shaft setup and variable oil pump. Otherwise, special attention has been paid to noise and vibration to make this a luxury-car engine; it gets a noise-deadening cam cover as well as special vibration-damping fasteners throughout.
The familiar 3.6-liter V6 is the same engine that’s offered elsewhere in the Cadillac lineup, in the CTS and SRX for instance, while the 2.5-liter engine is part of GM’s new Ecotec family and built in Tonawanda.
GM will likely reveal power numbers for the other engines, along with full details for the ATS, at the 2012 Detroit auto show in a few weeks.
