McLaren 675LT exhaust system

McLaren 675LT teased yet again, more details revealed

February 5, 2015

McLaren has teased the 675LT (Longtail) yet again, this time giving a sneak peek at the car’s rear-end. The new model will debut at the 2015 Geneva Motor Show and will be positioned as the top-most model of the McLaren Super Series range.

With the longtail treatment, the 675LT’s downforce will increase by 40% while the weight will reduce considerably. The standard 3.8-litre twin turbo V8 engine features lightweight components and new turbos. The engine produces 675 PS (666 bhp) and 700 Nm of torque. The new teaser reveals two circular titanium exhaust pipes that are positioned below the rear ‘Longtail’ Airbrake. The bespoke system will enhance performance and help in weight reduction.

The global debut of the McLaren 675LT will take place at the 2015 Geneva Motor Show on 3rd March.

More information is available in the press release below.


  • Active ‘Longtail’ Airbrake contributes to a 40 percent increase in overall downforce
  • 700 Nm (516 lb ft) produced by a heavily revised 3.8-litre twin turbo V8 featuring lightweight components and new turbos
  • Bespoke titanium crossover exhaust ensures optimised performance. See, and hear, it at:

The 675LT, the first McLaren in nearly two decades to wear the LT – or ‘Longtail’ – name, will stay true to the spirit of its iconic predecessor with aerodynamically optimised, dramatically enhanced styling that results in 40 percent more downforce than the 650S which it will sit alongside in the McLaren Super Series. A total power output of 675PS (666bhp), and torque figure of 700 Nm (516 lb ft) plus a focus on weight saving will ensure an electrifying, engaging and visceral driving experience.

These output figures are produced by a heavily revised 3.8-litre twin turbo V8 featuring lightweight components and new turbos. A controlled torque delivery of 600Nm (443 lb ft) ensures optimised acceleration and traction from a standing start in first gear, rising to the full 700Nm available from 5,500-6,500 rpm, through each of the other gears. A redesigned crossover exhaust system, bespoke to the 675LT, is formed from lightweight titanium. Two circular titanium exhaust pipes exit centrally through exposed bodywork below the rear ‘Longtail’ Airbrake. The new system is designed to optimise performance and reduce weight – another pillar of the LT ethos.

Available as a coupé only, the 675LT will join the core range of McLaren supercars later this year as a more track focused alternative to the established 650S Coupé and Spider. Together, they form the newly named McLaren Super Series which sits above the recently announced Sports Series in the range.

Further details of the McLaren 675LT, including its startling performance figures, will be released with the car’s global debut at the 85th International Geneva Motor Show, on Tuesday 3 March 2015.
