Meet The All-New 2021 McLaren 765LT: Lighter, Faster, And More Extreme

Reveal / 20 Comments

The McLaren 720S has been given the hardcore Longtail treatment.

Just as the McLaren 600LT and 600LT Spider represent the most hardcore version of the McLaren 570S Coupe and its spider sibling, it's time for the McLaren 720S to get the Longtail treatment. Say hello to the new McLaren 765LT, a faster, lighter, and even more engaging version of an already-sensational supercar.

Like other LT models, McLaren has gone to extreme lengths to make the McLaren 765LT as light and responsive as possible. Compared to the standard McLaren 720S, the 765LT is 176 pounds lighter thanks to the extensive use of carbon fiber, which has been applied to the body panels and components. Optimizations made to the powertrain and chassis, as well as the removal of comfort and convenience features also contribute to the car's extraordinary weight loss.

The elongated front splitter, new front bumper, front floor, side skirts, rear bumper, rear wing and lengthened rear diffuser are all bespoke and constructed in carbon fiber. Even the license plate holder is constructed from the lightweight material. Elsewhere, the hood, front fenders, doors, and rear fenders are made of lightweight aluminum as standard but are optionally available in carbon fiber to further reduce weight.

The weight reductions continue inside the track-focused interior, which features carbon fiber-shelled racing seats as standard that are a combined 39.7 pounds lighter than 720S sports seats. The bespoke lightweight central tunnel is also made of carbon composite material and has a panel thickness of just 0.03 inches. Carbon fiber has also been applied to the window switch surrounds, steering wheel clasp and Active Dynamics Panel surround. More carbon fiber options are available from McLaren Special Operations to save even more weight.

Lightweight Alcantara trim is also used extensively inside the cockpit and you can forget about luxuries such as floor carpets. Door stowage nets replace hinged door pockets and the steering wheel's reach and rake adjustment is manually operated. Air conditioning and an audio system are not fitted as standard but can be fitted at no extra cost if you can't live without these creature comforts.

For the first time on a modern McLaren LT, the thickness of the side window glass has been reduced. The windshield is also thinner, and the glazed C-pillars and rear screen are formed from lightweight, motorsport-style polycarbonate. The upper sections of the dihedral doors also feature lightweight carbon fiber panels.

A full-titanium, quad-exit exhaust system weighs only 24 pounds and is 40 percent lighter than a comparable steel system and 8.3 pounds lighter than the exhaust fitted to the 720S. As a result of these modifications, the McLaren 765LT has a dry weight of just 2,709 pounds when specified with options such as carbon fiber racing seats.

Under the hood is a 4.0-liter twin-turbo V8 producing 755 horsepower at 7,500 rpm and 590 lb-ft of torque at 5,500 rpm. That makes the 765LT the most powerful road-legal McLaren LT ever. 0-62 mph takes 2.7 seconds and 0-124 mph is achieved in 7.2 seconds. Power is sent through a seven-speed dual-clutch automatic.

The transmission gearing is also optimized for acceleration, allowing for near-instant throttle response and in-gear acceleration up to 15 percent quicker than the 720S. Carbon-ceramic brake discs and calipers from the McLaren Senna provide immense stopping power. At 614-hp per ton at its lightest dry weight, McLaren claims the 765LT boasts a best-in-class power-to-weight ratio, beating rivals by more than 49 hp per ton.

To complement the increased performance, the McLaren 765LT looks more aggressive than the standard 720S. The front splitter sits closer to the ground thanks to a 0.19-inch reduction in front ride height, which also creates more front downforce. Vertical blades on the outer edges of the front splitter help guide airflow around the front wheels. The nose is also 1.9 inches longer and the front bumper and splitter are positioned further forward.

An active rear wing stretches the rear by 0.31 inches. These changes add 2.24 inches to the overall length of the car. The wing's elevated static position increases downforce even when the wing isn't deployed, while the downforce-to-drag ratio increases by 20 percent over the 720S. The McLaren 765LT sits on new 10-spoke forged alloy wheels with titanium wheel bolts wrapped in bespoke Pirelli P Zero Trofeo R tires, saving 48.5 pounds over the standard 720S wheel and tires.

As the name suggests, production of the McLaren 765LT is limited to just 765 examples. Pricing and availability haven't been announced yet, but expect it to cost considerably more than the standard McLaren 720S, which starts at $299,000.
