Porsche's commitment to making road-legal track cars continues with the 2018 Porsche 911 GT3. Under its skin sits a naturally aspirated 4.0L flat-six based on the one used in all 911 race cars. It produces 500 hp, enough to propel the car — when equipped with the standard seven-speed dual clutch transmission — from 0-60 in 3.2 seconds and hit a top speed of 197 mph. The redesigned lightweight chassis includes Rear Axle Steering, which steers the rear wheels in either the same or opposite direction as the front, depending on the speed, while the carbon fiber wing provides additional downforce. The interior is racing-focused yet still comfortable, with a GT Sport steering wheel borrowed from the 918, sports seats, and an advanced CarPlay-compatible infotainment system with the ability to deliver detailed driving data to your phone.
The second entry in its core Super Series lineup, the McLaren 720S makes many strides over the 650S, yet retains the company's signature aerodynamic look. Its twin-turbocharged, 4.0L V8 produces 710 hp and is mounted in the middle of its carbon fiber chassis. Paired to a seven-speed SSG transmission, it propels the car from 0-60 in 2.8 seconds on its way to a top speed of 212 mph. That speed is harnessed from inside a refined interior, outfitted with premium leather, aluminum switches, and enough creature comforts to make this as fun to drive on the road as it is on the track.
