Introduced in 2015, McLaren's entry-level Sports Series has expanded to include no fewer than seven models in just a couple of years, including the racing versions, the cabriolet, and the bespoke MSO X. But, McLaren isn't stopping here and has already confirmed a new version is underway.

Teased in a couple of pictures, the upcoming sports car was confirmed to feature optimized aerodynamics, increased power, minimized weight, and track-focused dynamics. We don't know much about it yet, but McLaren provided a few valuable hints about the car that's often referred to as the 570LT. Let's have a closer look at what we already know about the most extreme Sports Series model ever built.

Continue reading for the full story.

1. The McLaren 570LT Could be Called the 600LT

While we've seen some of the car's new features, we still don't know under which name it will hit the market. Most outlets are calling it the 570LT, a name that brings together the numeric code of the range-topping 570S model and the letters that stand for Long Tail. Inspired by the original McLaren F1, the LT code has already been used for a hardcore version of the 650S, called the 675LT.

While 570LT is a pretty good name for this car, it doesn't make a lot of sense in McLaren's current naming scheme. All of the cars currently available feature their output in PS in their name. The 570S for instance has 570 PS (562 horsepower,) while the 540C comes with 540 PS (533 horses) on tap. With McLaren having already confirmed that the new sports car will have more power, the number in the name should increase.

One possible scenario is that McLaren will increase output from 570 to 600 PS (592 horsepower,) which would lead to a "600LT" name. On the other hand, it's not completely out of the question for the Brits to stick with "570" for this model, despite the extra oomph. Giving it a "600" badge might move the Sports Series too close to the Super Series, which begins with the 625C.

2. The McLaren 570LT Will Have Different Exhaust Layout

The teaser photos unveiled a few details about the new sports car and the new exhaust layout is arguably the most important. While the 570S feature two pipes on each side of the diffuser, the 570LT will have them fitted on the decklid.

This new layout was designed for aesthetics only. A shorter exhaust route will help reduce weight, as well as create a more aggressive engine note. It could also contribute to increasing the output by a few horses, but we won't know for sure until McLaren rolls out the official details.

Needless to say, having a couple of exhaust pipes exiting through the decklid and pointing upward is as cool as it gets!

3. The McLaren 570LT Will Have 592 Horsepower

The common consensus is that the hardcore 570LT will have 600 PS (592 horsepower). That would be a 25-PS increase over the 570S, an upgrade that would make sense given the power difference between the 650S and the 675LT. While it might not seem that big of an upgrade at first glance, the extra 25 horsepower will make a significant difference in a car that's lighter, more aerodynamic, and more nimble. The figure also makes sense given the fact that McLaren usually chooses round output figures and badge numbers for its supercars. It's still a guessing game as of this writing, but 600LT definitely sounds better than 590LT or 610LT.

4. You Won't See it on Public Roads too Soon

The hardcore version of the 570S will be unveiled on June 28, at the 2018 Goodwood Festival of Speed. That's just a week from now, so we won't have to wait too long to find out everything about it. But while McLaren will showcase an example at Goodwood, customer deliveries won't begin sooner than six months or so from now. McLaren has a really tight schedule and a busy factory, so new models often have to wait for older cars to go out of production before hitting the assembly line. The Brits are indeed working hard to increase output in Woking, and the 570LT could go into production sooner than expected, but don't get your hopes up to see one in the metal (outside auto shows of course,) until the fourth quarter of 2018.
