Right now, the most powerful Porsche 911 in the new 992-generation family is the 2020 Carrera S, which cranks out a respectable 443 horsepower from its 3.0-liter twin-turbo flat-six engine. This won't be the case for long, however, as more powerful variants are coming including the new 911 Turbo, which is expected to debut later this year with over 600 horsepower, and the all-new 911 GT3, which will reportedly get a naturally aspirated 4.0-liter flat-six producing around 550 hp. If, however, you can't wait until then, UK tuner Litchfield has given the 992-generation Carrera a significant power increase.

After working its magic on the 2020 Toyota GR Supra, Litchfield has managed to extract 572 horsepower and 480 lb-ft of torque from both the Carrera and Carrera S's flat-six – that's a 200 hp gain over the standard Carrera. This was achieved by a simple re-calibration of the engine management system.

It's all done by plugging a connector into the 911's ECU without removing anything or opening any panels. Effectively, this makes the new 992-generation Carrera as powerful as the previous-generation Turbo S. Despite this, Litchfield asserts the modified Carrera is "just as smooth and civilized to drive as the standard car."

Litchfield hasn't said how this modification affects the Carrera's performance, but it should be much quicker off the line than the standard car. For reference, the 2020 Carrera S will do the 0-62 mph sprint in 3.5 seconds, while the all-wheel drive 4S takes 3.4 seconds. Top speed is rated at 191 mph for the Carrera S and 190 mph for the 4S.

The tuner is also developing a performance exhaust that will offer improved engine performance, save weight, and enhance the exhaust note. If you just want the software upgrade, Litchfield is charging £1,194 ($1,460).
