McLaren 675LT Officiallly Unveiled with 675PS

McLaren announced the brand-new 2016 675LT today. Basically speaking the 675LT is based on the current McLaren 650S.


Major changes made to the 675LT are:

– 33% of parts are different
– 220 lbs weight savings
– Same 3.8L turbocharged V8 engine, but tuned to 675PS (650S has 650PS, by its name)

For your reference, the 675LT is using the similar carbon fiber composite chassis in the 650S, with 220lbs less weight, the 675LT’s dry weight is as light as only 2,711 lbs.

The M838T 3.8L twin-turbo V8 is designed with the help from Ricardo. This root of the M838T can be traced back to Nissan’s VRH35ADE racing engine. The turbocharger on the M838T is sourced from Mitsubishi. Another notable feature of this engine is its exhaust system is made of titanium (another famous example is the Lexus LFA V10 engine)

– 0-62 mph in 2.9 seconds; 0-124 mph in 7.9 seconds
– 220 lbs weight savings makes the 675LT the lightest in its class, and gives a power-to-weight ratio of 4 lbs per bhp (549PS per ton)
– 33 percent of parts are different from the 650S, which it sits alongside in the McLaren Super Series
– Five unique ‘By McLaren’ hero specifications to be offered
– Global premiere at the Geneva Motor Show in March 2015 on stand 1240, at 12.15 CET (11.15 GMT / 6:15AM EST)

The McLaren 675LT will make its world debut at the 85th Geneva Motor Show, with a clear focus on outright performance, weight reduction and ultimate levels of driver engagement – all key attributes of a ‘Longtail’ McLaren. Offered as a Coupe only, the 675LT will be the most track-focused, yet road legal, model in the McLaren Super Series, with a power to weight ratio that eclipses established rivals. The sprint from 0-62 mph (0-100 km/h) takes just 2.9 seconds, with controlled torque delivery ensuring optimized traction off the line. Acceleration continues at a relentless pace with the 124 mph (200 km/h) barrier broken in 7.9 seconds, on to a top speed of 205 mph (330 km/h).

The first images of the car show a darker side of the McLaren brand than has been seen before. Aggressive styling cues and performance enhancements include the extended carbon fiber front splitter, extended door blade with additional cooling intake, and circular twin titanium exhaust pipes, giving a hint to the performance available within the most powerful and lightweight model in the McLaren Super Series. The active ‘Longtail’ Airbrake is 50 percent bigger than the one fitted to the 650S yet, due to its carbon fiber structure, is actually lighter. This is just one of the enhancements that add up to a dry weight of just 2,711 lbs (1,230kg). With a modified V8 engine delivering, as the name suggests, a power output of 666 bhp (675PS), the 675LT delivers a mighty power-to-weight ratio of 4 lbs per bhp (549PS per ton).

The 675LT is as fully track-focused as it is road legal with a third of its parts modified to suit its purpose compared with the 650S Coupe and Spider that continue in production alongside it. Yet like its iconic predecessor, the McLaren F1 GTR ‘Longtail’, from which the LT name is derived, this is a car that is as exciting to look at as it is to drive.

Weight reduction has been a key focus throughout the development program for the 675LT, and the result is a savings of over 220 lbs (100kgs) beyond the other models in the Super Series – in line with the savings made by the 1997 McLaren F1 GTR ‘Longtail’ over its hugely successful predecessors, despite the revised bodywork. This weight savings has been achieved through extensive use of carbon fiber for the body panels, along with lightweight engine, chassis and body structure parts.

Below a newly designed front bumper sits a prominent carbon fiber front splitter, which works the air harder, complimenting new front wing end plates to increase downforce levels over the front bodywork. The turbulent air from the front wheel arches is ‘cleaned’ as it flows towards the rear bodywork by sculpted carbon fiber side sills which run the full length of the lower bodywork. A subtle air intake is incorporated ahead of the leading edge of the rear wheel arch, below a more pronounced side intake behind the door, both of which feed clean cool air into the side-mounted radiators.

The aero balance is optimized by the active ‘Longtail’ Airbrake which, as with the McLaren F1 GTR ‘Longtail’, is larger – 50 percent larger than on other Super Series models. The reprofiled design flows into the lines of the new carbon fiber rear wings. Two circular exhaust pipes, forged from titanium, exit centrally through exposed bodywork below the rear wing. Despite a more complex design, the bespoke crossover system is designed to optimize performance and reduce weight, saving 2.4 lbs (1.1kg). The rear deck and sections flanking the exhaust pipes remain exposed; designed to evacuate hot air from the engine bay as efficiently as possible, while a lightweight Plexiglas® rear screen features further louvers. A louvered carbon fiber rear bumper reduces air pressure over the rear wheels, while the rear design is completed with a dramatic integrated carbon fiber diffuser.

The 675LT is offered in five ‘By McLaren’ hero specifications, which includes four bespoke colors never previously offered: Silica White, Delta Red, Napier Green and Chicane Grey are all newly formulated paint hues for the 675LT. The famous heritage McLaren Orange completes the themes unique to the model.

Inside the 675LT, the purposeful driver-focused cabin gives even further indication of track potential. A pair of ultra lightweight carbon fiber-shelled bucket seats, upholstered in Alcantara® as standard and modelled on those in the McLaren P1™, provide comfort and support with no compromise on overall weight. Each of the five LT color themes is complimented within the stripped out interior, with carefully selected materials and colors.

The McLaren 675LT will make its global debut at the 85th Geneva Motor Show at 12.15 CET (11.15 GMT / 6:15AM EST) on Tuesday, March 3, 2015.
