Today, Porsche announced the arrival of the latest Porsche 911 Turbo–wait, didn’t they do that in September?

Oh, right. That was the 911 small-tee-turbo, the entry-level model that uses a turbocharged engine to keep up performance while cutting fuel consumption in daily driving. Today’s announcement is indeed the 911 Turbo and Turbo S, the ne-plus-ultra of road-going 911s (not counting the track-biased GT2 and GT3 models), which Porsche says now boast 20 more horsepower, quicker acceleration, and higher top speeds than the cars they replace. Those being the 911 Turbo and Turbo S, not the 911 turbo.

Confused yet? Let us help straighten you out.

Where the base 911 and 911 S now have a 3.0L turbo flat six that propels those models to 100 km/h from a standstill in 4.2 and 3.9 seconds respectively, the new 911 Turbo cars share a 3.8L six that makes 540 hp in the 911 Turbo, and 580 in the Turbo S, increases of 20 hp in both cases. That’s enough to move the 911 Turbo (okay, we’ll stop that now) from zero to 100 km/h in 3.0 seconds, while the Turbo S does the same sprint in 2.9. Top speeds are up, too, to 320 km/h in the Turbo (five km/h higher) and 330 in the Turbo S, an increase of 12 km/h.

Interestingly, those power increases were achieved through different means: in the 911 Turbo, the gain comes courtesy of updated intake ports, and new fuel injectors working under higher fuel pressure. The Turbo S’ boost comes from new turbochargers with bigger compressors. Porsche doesn’t say how much torque the new engines crank out, but would nonetheless like to remind us all that it’s the only car manufacturer using variable turbine geometry in turbocharged gasoline engines.

Offered from the start in coupe and convertible forms, Porsche says a new front end makes the car look wider, and there’s a new engine cover out back designed to optimize engine air induction. Inside, Porsche’s new infotainment system is standard, as is a Bose stereo; a Burmester system is an option (and probably a very expensive one).

Speaking of expensive, 911 Turbo coupe pricing starts at $181,800, with the convertible coming in at $195,800. Turbo S prices are $214,800 (coupe) and $228,800 (convertible). All four variants will go on sale across Canada in the second quarter of 2016.
