McLaren has finally revealed its latest hardcore, track-ready sports car. It's the 2019 McLaren 600LT, with the LT standing for "Longtail," a designation that started with the McLaren F1 GTR racecar. According to the company, this is only the fourth car in the company's history to have the name. And like the previous LT models, it features more power, less weight, and a bunch of special performance parts to separate it from its more common brethren.
On the power side, McLaren upgraded the twin-turbocharged 3.8-liter V8's cooling system, and fitted a new exhaust system. That exhaust exits out the top, as shown in teaser images leading to the reveal, and it reduces the amount of back pressure in the system. The upgrades help the engine to make 592 horsepower and 457 pound-feet of torque. That's an increase of 30 horsepower and 14 pound-feet of torque over the 570S.
