McLaren Automotive has unveiled the 788HS at the 2026 Goodwood Festival of Speed, marking the final iteration of its 720S-based supercar lineage. Featuring a 777bhp twin-turbocharged V8, the model incorporates advanced aerodynamics and a lightweight 1265kg dry weight, establishing a power-to-weight ratio of 623PS per tonne—the highest in the series, according to McLaren.
Engineering the Final 720S Evolution
The 788HS serves as the third road-legal vehicle to earn the “High Sport” designation, following the MP4-12C HS and the MSO HS. Under the rear deck, the M840T 4.0-litre twin-turbo V8 has been tuned to deliver 777bhp at 7500rpm and 590lb ft of torque at 5500rpm. McLaren reports the engine reaches an 8500rpm redline, supported by lightweight forged pistons and twin fuel pumps.
Performance Metrics and Aerodynamic Gains
The 788HS achieves a 0-62mph sprint in 2.8 seconds and hits 124mph in 7.0 seconds, with a top speed of 205mph. To manage this output, McLaren engineers developed an aerodynamic package that generates ten percent more downforce than the 765LT. Key components include an S-Duct bonnet, a raised active rear spoiler, and a Formula 1-inspired rear diffuser.
Thermal management is integrated into the aero design; the under-wing louvres are specifically engineered to extract heat from the powertrain. For road feedback, the manufacturer introduced a unique engine-mount calibration designed to increase vibration transmission to the driver without compromising comfort on longer journeys.
Chassis and Interior Refinements
While maintaining the Proactive Chassis Control III hydraulic suspension, the 788HS features model-specific spring and damper geometry. The front ride height sits 5mm lower than the 750S. Stopping power is provided by carbon-ceramic discs sourced from the McLaren Senna, paired with six-piston forged aluminium calipers.
Inside the cabin, the focus remains on weight reduction. The interior features a carbon-fibre centre console and a steering column-mounted instrument display. According to Henrik Wilhelmsmeyer, McLaren Automotive chief commercial officer, the vehicle was designed with a “singular focus” on balancing performance, sound, and individuality to conclude the series that began with the 720S.
Pro Tip: The Value of “High Sport”
Collectors often track these models for their specific chassis tuning and MSO (McLaren Special Operations) personalization options, such as the full exposed carbon-fibre bodywork offered for the 788HS.
