The McLaren 765LT is a high-performance, limited-production supercar that represents the ultimate evolution of McLaren’s Super Series lineup. It is an extreme, track-focused version of the McLaren 720S, with the "LT" standing for Longtail—a nod to McLaren’s racing heritage and its focus on weight reduction, increased power, enhanced aerodynamics, and track performance.
1. Overview
Class: Supercar.
Production: Limited to 765 units.
Body Styles: Available in coupe and spider (convertible) versions.
Inspiration: The "Longtail" designation comes from the McLaren F1 GTR Longtail, which competed in endurance racing in the 1990s, emphasizing aerodynamics, lighter weight, and increased performance.
2. Engine and Performance
Engine:
The McLaren 765LT is powered by a 4.0-liter twin-turbocharged V8 engine (M840T), which is an enhanced version of the engine found in the 720S.
Power Output: 755 horsepower (765 PS) and 800 Nm (590 lb-ft) of torque.
Performance:
0-100 km/h (0-62 mph): 2.8 seconds.
0-200 km/h (0-124 mph): 7.0 seconds.
Top Speed: Approximately 330 km/h (205 mph).
Transmission:
The car features a 7-speed dual-clutch transmission that delivers lightning-fast gear shifts, optimized for high-speed performance on both the track and the road.
Weight Reduction:
The 765LT benefits from extensive weight-saving measures, making it 80 kg (176 lbs) lighter than the already lightweight 720S. The dry weight is around 1,229 kg (2,709 lbs).
The weight savings come from extensive use of carbon fiber, a lighter exhaust system, thinner glass, and the removal of some non-essential features.
3. Aerodynamics
Longtail Design:
The “Longtail” name comes from the extended rear section, which is designed to improve aerodynamics and high-speed stability.
The active rear wing is larger and more functional than the one on the 720S, offering improved downforce, especially under braking and at high speeds.
Enhanced Downforce:
The front splitter, rear diffuser, and side skirts are all optimized for increased downforce and improved airflow around the car.
Overall, the 765LT generates 25% more downforce than the 720S, enhancing grip and cornering speeds, particularly on the track.
4. Chassis and Suspension
Race-Tuned Suspension:
The suspension system on the 765LT is derived from McLaren’s experience in motorsport and features recalibrated Proactive Chassis Control II. This system monitors the car's dynamics and continuously adjusts the suspension to provide optimal performance on both track and road.
Brakes:
The car is equipped with carbon-ceramic brakes as standard, offering extreme stopping power and endurance for track use. The Formula 1-inspired calipers are lighter and more heat-resistant.
For even better braking performance, an optional MSO-defined Senna brake upgrade is available, offering the highest performance braking system McLaren offers.
Tires:
The 765LT comes with Pirelli P-Zero Trofeo R tires, which are semi-slick and designed for optimal grip and performance on both road and track.
5. Interior
Minimalist Approach:
Inside, the cabin is focused on performance, with weight savings being a priority. Alcantara and carbon-fiber dominate the interior materials.
Carbon-fiber racing seats are standard, offering minimal padding but maximum support for high-speed driving and cornering.
Driver-Focused Controls:
The 765LT features McLaren’s active dynamics panel, allowing the driver to fine-tune the handling, suspension, and powertrain settings via Comfort, Sport, and Track modes.
The digital instrument display provides essential driving information with an option to show critical data like gear selection and RPM in track mode for a more focused driving experience.
Sound System:
To save weight, the car comes without a traditional sound system or air conditioning as standard, but both can be added as options at no additional cost for those who desire more comfort.
6. Exhaust System
Titanium Exhaust:
One of the highlights of the 765LT is its titanium exhaust system with quad-exit pipes. The exhaust is designed to be lightweight and to produce a more aggressive and louder sound than the 720S.
The tone of the exhaust changes based on the rev range, offering a unique, high-pitched sound as the revs climb, which enhances the driving experience.
7. Track Focus
While the 765LT is street-legal, it is heavily optimized for track performance. Every aspect of the car is designed to improve lap times and provide a more engaging, visceral driving experience.
Weight-to-power ratio, advanced aerodynamics, and precise handling make it a formidable weapon on any race track.
8. Limited Production and Exclusivity
Only 765 units of the McLaren 765LT will be produced worldwide, making it highly exclusive and desirable.
Each car can be further customized through McLaren Special Operations (MSO), allowing buyers to add bespoke features and finishes to their 765LT.
