McLaren is set to reveal the new 675LT at the upcoming Geneva Motor Show, but before it does, the F1 team turned exotic automaker has been peppering us with teasers of the new track-focused supercar.

The 675LT promises a raft of enhancements over the 650S on which it's based, starting with the engine: McLaren's ubiquitous 3.8-liter twin-turbo V8 has been fitted with lightweight components and new turbo spools to drive output up to 666 horsepower (675 in metric terms, hence the first part of the nameplate) and 516 pound-feet of torque. It also gets revised bodywork with a longer tail (hence the LT) that helps produce 40 percent more downforce, and a dual-tip titanium exhaust.

We'll have more on the new McLaren 675LT as its debut approaches less than a month from now, when it will form part of the brand's newly aligned Super Series (alongside the 650S and Asian-market 625C) above the upcoming entry-level Sports Series. But in the meantime, you can hear that upgraded engine roar through the new exhaust in the video clip above.

- 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.
