The McLaren 788HS is a limited-production supercar producing 777 BHP, marking the final iteration of the lineage that began with the 720S. Capped at 200 worldwide units, the model delivers a power-to-weight ratio of 618 BHP per tonne and a top speed of 330 kmph, according to McLaren.
Pushing the M840T V8 to its Absolute Limit
McLaren has reworked the 4.0-litre twin-turbocharged M840T V8 to reach a peak output of 777 BHP and 81.6 kgm. The engine hits peak power at 7,500 rpm and sustains pull up to an 8,500 rpm red line.
Weight reduction is the primary driver behind the 788HS’s performance. With a dry weight of 1,265 kg, it achieves the highest power-to-weight ratio in the history of the 720S, 750S, and 765LT family. This allows the car to hit 100 kmph in 2.8 seconds and 200 kmph in 7.0 seconds.
Did you know? Before the 788HS, it appeared only on the MP4-12C HS and the MSO HS.
Aerodynamic Evolution and Downforce Gains
The 788HS introduces the most advanced aerodynamic package ever fitted to this specific platform. McLaren reports a 10% increase in downforce over the 765LT, a model already known for its aggressive track focus.
This gain comes from a new carbon fibre suite including a multi-zone front splitter, an S-Duct bonnet, and a Formula 1-inspired rear diffuser. An active rear spoiler manages stability at high speeds, ensuring the car maintains the balance typical of McLaren road cars.
Chassis Refinement and Senna-Derived Braking
To sharpen handling, McLaren lowered the front ride height by 5 mm compared to the 750S. The Proactive Chassis Control III linked-hydraulic system features bespoke calibration and adaptive dampers for better body control on both circuits and public roads.
Stopping power comes from carbon ceramic brake discs derived from the McLaren Senna. These are paired with six-piston forged aluminium front calipers and integrated cooling ducts to prevent fade during sustained high-speed use.
| Metric | 788HS Specification |

| Max Power | 777 BHP |
| Dry Weight | 1,265 kg |
| 0-100 kmph | 2.8 Seconds |
| Top Speed | 330 kmph |
Driver Engagement and MSO Personalization
The 788HS is the first in its series to feature a centre-lock wheel system with lightweight forged alloy wheels. To improve the sensory experience, McLaren installed a quad-exit titanium exhaust and revised induction symposers to amplify the V8’s character.
Every unit is tailored through McLaren Special Operations (MSO). Owners can choose a full Visual Carbon Fibre body in gloss or satin finishes. Inside, the cabin retains the McLaren Infotainment System II and steering-column-mounted binnacle, but adds unique upholstery perforation and a dedicated HS plaque.
