From the F1 GTR to the 675LT, McLaren has had a long history with 'Longtail' variants of both their road-going supercars and race cars. Now, a new model has joined the Longtail family called the 600LT. The 600 Longtail is the new range topping model in McLaren's Sport Series.

Based on the 570S, the 600LT takes on a more aggressive look and is said to be inspired by the 675LT and F1 GTR Longtail before. It comes with an extended carbon fiber body which is 730mm longer than the 570S. It also weighs 96 kg less with a dry weight of 1,247 kg thanks to new carbon fiber parts developed by McLaren Special Operations including the roof and carbon front fenders.

In order to make the 600LT standout, it has a longer front splitter and rear diffuser. There are also new side sills and a fixed rear wing, all of which helps increase downforce. Did I mention that the exhaust now exits going to the top? All-in-all, McLaren says the new LT has 23-percent new parts fitted on it.

Much like the exterior, the inside of the 600LT also gets a makeover. It takes on a minimalist, track-focused interior and is paired with the same carbon fiber racing seats as the P1. Buyers can also spec their 600LT to be fitted with even lighter carbon fiber seats found on the Senna.

Powering the 600LT is the same 3.8-liter bi-turbo V8 found on the 570S. However, McLaren has upped its horsepower 30 PS as it now produces 600 PS and 620 Nm of torque. Combine with the carbon fiber diet, the new Longtail now does 0-100 km/h in just 3.2 seconds and 200 km/h in 9.5 seconds. Top speed is rated at 328 km/h.

McLaren didn't mention how many units of the 600LT will be produced. They did say however that is is 'strictly limited' will only last for 12 months once production begins in October 2018.
