Porsche 911 enthusiasts tend to be obsessive about their engines. Some won’t touch anything that isn’t air-cooled, convinced that everything went wrong when emissions and efficiency finally forced radiators into the car. Others love the “Mezger” engines; designed by engineer Hans Mezger, they trace their roots to the 1998 Le Mans-winning car, and no Porschephile can resist the added shine of a motorsports halo.
I’m quite sure none of them will feel the same way about the powertrain in the new 911 Carrera GTS T-Hybrid (MSRP: $175,900), and I think that’s a crying shame. Because not only is the car’s technology rather cutting-edge—you won’t find this stuff outside an F1 car—but having spent several days behind the wheel, I can report it might just be one of the best-driving, too.
T-Hybrid
This is not just one of Porsche’s existing flat-six engines with an electric motor bolted on; it’s an all-new 3.6 L engine designed to comply with new European legislation that no longer lets automakers rich out a fuel mixture under high load to improve engine cooling. Instead, the engine has to maintain the same 14.7:1 stoichiometric air-to-fuel ratio (also known as lambda = 1) across the entire operating range, thus allowing the car’s catalytic converters to work most efficiently.
