666-HP track-focused supercar sprints to 62 mph in 2.9 seconds and will be formally unveiled in Geneva next week.
This is McLaren's answer to the Ferrari 458 Speciale. The high-performance variant of the 650S comes with more power than the car it's based on, less weight, and with a long-tail aerodynamic design. The coupe-only 675LT is named after its 675 metric power (equating to 666 devilish horsepower), and the 1997 F1 GT "Longtail" homologation special. 50% of the parts in the 3.8-liter twin-turbo V8 are new, from the turbos and camshafts to a faster-flowing fuel pump and upgraded cylinder heads and exhaust manifolds.
So new is the engine in fact, McLaren has given it a new name: M838TL. All that power, as well as 516 lb-ft of torque, is sent to the rear wheels via a seven-speed dual-clutch automatic gearbox. More power is married to less weight, with the 675LT weighing in at 1,230 kg, so 100 kg less than the 650S, thanks to extensive use of carbon fiber and other lightweight materials. The result is a 0-62 mph time of 2.9 seconds, 0-124 mph in 7.9 seconds and a top speed of 205 mph – a 2 mph drop from the 650S caused by the additional drag of the new aerodynamics. A wonderful front chin splitter and longer active rear spoiler McLaren calls the "Longtail Airbrake," which is 50 percent larger than that on the 650S, makes the 675LT 1.5 inches longer than the 650S.
In total, a third of the car's parts are new compared to the 650S. Visually, we are really digging the aggressive styling with the P1-inspired rear end, two massive titanium circular exhaust outlets, the horizontal LED taillights, and all those functional scoops and vents. Being road legal, the track-focused 675LT's interior is relatively sparse but still boasts Alcantara-wrapped carbon-shelled seats borrowed from the P1 and a touchscreen infotainment system. McLaren will offer the 675LT in five 'By McLaren' specifications inspired by famous liveries and colors, including four new bespoke colors of Silica White, Delta Red, Napier Green and Chicane Grey.
It will sit above the 650S in the 'Super' models range, with the P1 in the 'Ultimate' range and upcoming new smaller models in the 'Sports' range. Limited in production, the McLaren 675LT will command in the region of $350,000 when it goes on sale, with deliveries to commence in the fall.
