After nearly two decades, a McLaren model will wear the LT (for Longtail) moniker and this here is the second teaser video for the new 675LT in which we hear the turbo’d V8 for the first time.

McLaren also confirmed the 3.8-liter twin-turbocharged V8’s output figures at 675PS (666hp) and a controlled torque delivery of 600Nm (443 lb ft) in first gear, rising to the full 700Nm (516 lb-ft) available from 5,500-6,500 rpm, through each of the other gears.

These figures represent a slight increase in power and torque over the 650S’ V8 that delivers 650PS (641hp) and 678Nm (500 lb-ft), with the British sports car maker stating that improvements include lighter components and new turbos. The 675LT also gets a bespoke crossover exhaust system formed from lightweight titanium.

As for the new rear end, we’re told that the Active ‘Longtail’ Airbrake “contributes to a 40 percent increase in overall downforce”.

More details are to be released in the next few weeks leading to the Geneva Motor Show.
