The McLaren 788HS debuted at Goodwood Festival of Speed on July 9, 2026. Two hundred cars, split 100 coupe and 100 Spider, all built on the same 4.0-litre twin-turbo V8 that has been in the Super Series since the 720S launched in 2017.
What McLaren changed
- Engine: 4.0-litre M840T twin-turbo V8, 788 PS (777 hp), 800 Nm. Uprated turbos, revised intake, new titanium exhaust.
- Weight: roughly 30 kg lighter than a 750S through a carbon roof, forged wheels, thinner glass and reduced sound-deadening
- Aero: larger front splitter, active rear wing tuned for higher downforce at the expense of top speed
- Suspension: stiffer springs, revised damper tune, hydraulic anti-roll retuned for the added downforce
- Transmission: 7-speed dual-clutch (unchanged), RWD only
- Production: 200 total (100 coupe + 100 Spider), all allocated
The 788HS is not faster to 100 km/h than a 750S in any meaningful way. It is faster around a lap. That's what the "HS" is telling you.
The end of an era for McLaren's Super Series
McLaren's Super Series has been the M840T's home for nine years. Every 720S, 720S Spider, 750S, 750S Spider, and now 788HS shares the same engine block, same head, same displacement. The next Super Series car will not.
McLaren has confirmed the W1 uses a new MHP-8 twin-turbo V8 with a hybrid assist system. Whatever replaces the 750S below the W1 will follow that architecture. That makes the 788HS the last McLaren Super Series car with a combustion-only powertrain, and the last car to run the M840T. Both facts will matter to collectors before they matter to drivers.
At 200 units, this is neither a real limited edition (Sabre / Elva / Solus GT territory, all sub-100 cars) nor a proper production run. It is exactly enough to reward the customers who bought a 720S at launch and stayed for the follow-up. If that group is who you are, the 788HS is the send-off. If not, this car is going straight from delivery to Sotheby's.
See where it lands against the current supercar field on our fastest cars list.
