Heel-toe shifting is becoming a lost art. This is how our grandparents had to drive, using your right foot to brake and your toes to blip the gas pedal. Gradually, American cars adopted heavy flywheels that eliminated the shuffle at the expense of double-clutching instead. Only the world's best drivers can execute both methods in a twinkling of an eye, so watch Mark Webber hot lap the new 718 GTS 4.0 at Estoril.
While many people hoped the 4.0L would be the same 500 horsepower monster from the Porsche 911 GT3 RS for sale, that one wouldn't fit. So engineers used the architecture of the 718 Series flat-four and added a pair of cylinders. This mid-engined monster offers 400 horsepower and 310 lb-ft of torque through a six-speed manual.
