Ferrari’s 458 Speciale has a new rival because McLaren unveiled the all-new 675LT. The new vehicle will be officially unveiled next month at the 2015 Geneva Motor Show, the 675LT will be offered only as a coupe and will be company’s most track-focused model in the McLaren Super Series. According to McLaren the LT model designation stands for ‘Longtail’ and the 675LT promises to be a modern interpretation of the iconic McLaren F1 GTR ‘Longtail’.
Compared with the standard 650S, the 675LT shows a more aggressive look and arrives with an extended carbon fiber front splitter, an extended door blade and additional cooling intake. The rear end shows a new bumper, stylish circulat twin titanium exhaust pipes but also a new active ‘Longtail’ Airbrake which is 50 percent bigger than the one found on the 650S.
The most interesting thing is that the new airbrake is actually lighter than the standard one thanks to the carbon fiber structure. The louvred carbon fiber structure of the rear bumper reduces air pressure over the rear wheels. Meanwhile, the rear deck and sections flanking the exhaust pipes remain exposed, able to evacuate hot air from the engine bay.
The interior was stripped out and shows ultra lightweight carbon fiber-shelded bucket seats wrapped in Alcantara as standard. Moreover, the air conditioning controls are now integrated in the touchscreen infotainment system. McLaren says that the 675LT will be offered in five ‘By McLaren’ hero specification, with four bespoke colours that were never previously offered such as Silica White, Delta Red, Napier Green and Chicane Grey.
The vehicle is powered by an enhanced version of the 3.8-liter M838TL engine that features more than 50 percent new components. Upgrades include more efficient turbos, detail design changes to the cylinder heads and exhaust manifolds, new camshafts and lightweight connecting rods but also a faster-flowing fuel pump and delivery system.
The total output delivered by the engine is 675 hp. McLaren’s new 675LT is 100 kg (1,230 kg) lighter than the standard 650S and according to the company, the power-to-weight ratio is 549 hp per tonne. As a result, the 675LT zooms from 0 to 100 km/h (62 mph) in 2.9 seconds, to 200 km/h (124 mph) in 7.9 seconds, while top speed is 330 km/h or 205 mph.
