McLaren just released a teaser photo that partially shows the rear section of a car that looks a lot like the 570S. But a closer look reveals significant modifications, which suggests that we are probably looking at a hardcore version of the sports car.

Although it doesn't include much of the car, the picture unveils a bunch of new features that can't be found on the 570S. For starters, the carbon-fiber diffuser has a different shape at the corners, while the vertical fins have been revised as well. More importantly, there's no exhaust pipe, also placed at the corner on the 570S. The tailpipe was clearly relocated to the center of the fascia (or maybe it has a new side-exiting layout?), which hints at a revised drivetrain.

Take a close look below, and you'll notice that the tires are also different. Not only is it wider than the usual rubber seen on the 570S, but it also has a different tread. It looks a lot like the Pirelli P-Zero Trofeo R tire, which is used on more track-focused vehicles. Moving to the corner of the bumper, there's a new cutout and a vertical blade for improved aerodynamics.

While the rest of the car remains hidden, we're definitely looking at a sports car placed atop the 570S. And, based on reports from the past, it should wear an "LT" badge.

Rumors of a more track-focused Sports Series model surfaced back in March, when Autocar reported that the vehicle has already been developed, with McLaren waiting for a slot in its busy production plans. The outlet also said that it would deliver 600 horsepower and that it would be called 570LT. However, this name doesn't make much sense in the company's current nomenclature, so it's more likely that it will be launched as the 600LT. With McLaren badges usually including the engine's output in PS, the 600LT would have 600 PS or 592 horsepower. That's a 30-horsepower increase over the 570S.

But while it will sport the "LT" badge, it probably won't get the extensive modifications we've seen on the 675LT. A slightly longer deck lid is likely in order to keep it in line with the F1 Long Tail heritage, but it won't be as radical as its bigger sibling. The 600LT will be a bit quicker at the track though, and as it usually happens, it will be significantly more expensive.

An official unveiling could take place this summer, possibly at the 2018 Goodwood Festival of Speed in July. The new sports car will join the existing 570S, 540C, and 570GT in the Sports Series lineup. Stay tuned for updates.
