McLaren re-establishes the 'Longtail' heritage with the official introduction of the 675LT at the 85th International Geneva Motor Show, focusing on light weight, optimised aerodynamics, increased power, track-focused dynamics and driver engagement.

With only 500 units to be made available, the McLaren 675LT is formally the most exclusive, lightest, most powerful and fastest model in the McLaren Super Series.

In the heart of the 675L is the lightweight carbon fibre MonoCell chassis, shared with each model in the Super Series, but the chassis set up and powertrain are customized, with a third of overall parts and components modified.

Using a more aggressive setup, the 675LT has a unique track-focused feel but with the adjustable ProActive Chassis Control, it will still maintain daily drivability and a comfortable ride.

Staying true to the original 1997 McLaren F1 GTR ‘Longtail,’ the 675LT will also have a wider track, front and rear by 20mm.  The lightweight springs have been stiffened by 27% at the front and 63% at the rear for improved body control and make a 40% increased in downforce possible.

The bodywork has been revised and given newly-developed suspension geometry for the lightweight uprights and wishbones based on the learnings from the McLaren P1™.

Tipping in at 1,230kg (dry weight), the 675LT is officially the lightest model in the already lightweight Super Series saving more than 100kg.

Still using the seven-speed SSG transmission found in the other Super Series models, the 675LT will have the familiar Normal, Sport or Track modes but recalibrated for better performance.  Throttle response has been optimized and gearshifts are up to twice as fast as previously offered.

It will come F1’s ‘Ignition Cut’ technology which sees a momentary cut of the fuel spark on gearshift making the fastest gear change possible and the all-new Electronic Stability Control (ESC) calibration, giving the driver an even greater level of control over the throttle and brake inputs.
