McLaren 788HS Revealed: Specs, Power, and Everything We Know

Saudi Arabia: McLaren has just revealed the 788HS, the hardest version of the 720S family. With only 200 units (100 coupe/100 convertible), no hybrid compromise, and a lightweight V8, it is the final send-off for the iconic McLaren 720S/750S platform. It makes 788 PS (777 hp) from a 4.0-litre twin-turbo petrol V8 and weighs just 1,265 kg dry. 

Power and Performance Specs

The engine is a reworked version of McLaren's 4.0-litre twin-turbocharged M840T V8. This is the most powerful production version of that engine ever fitted to a Super Series car.

Aerodynamics Borrowed From Formula 1

With the carbon-fibre aero package, the 788HS generates 10 percent more downforce than the 765LT. Here are thekey  aero hardware details:

• Multi-zone carbon-fibre front splitter
• S-Duct bonnet
• Raised active rear spoiler
• Louvred under-wing panel
• Formula 1-inspired rear diffuser
• Optional full Visual Carbon Fibre body in gloss or satin
• Gloss black roof scoop, standard on Coupe

Chassis, Brakes and Wheels

The 788HS uses a bespoke tune of McLaren's Proactive Chassis Control III linked-hydraulic suspension. The front ride height sits 5 mm lower than the 750S, sharpening turn-in and making the nose feel more responsive.

The brakes are carbon ceramic discs taken from the McLaren Senna and paired with six-piston forged aluminium front calipers and dedicated cooling ducts. Carbon ceramics help it resist heat fade. That is a very practical addition for the Saudi summer track days and mountain roads as well. It is the first car in the family to get the Centre-lock wheels that sit above the Super Lightweight forged alloys. The Centre-locks hold the wheel firmly and save the weight over conventional five-bolt hubs. 

Inside the Cabin

The 788HS 2026 features an ultra-lightweight, driver-focused cockpit. The centre console is made from lightweight carbon-fibre and comes with HS badging, a unique seat perforation pattern and a numbered plaque. McLaren Infotainment System II is standard. Powertrain and Handling mode controls are on the steering wheel, so you can change the driving character without even moving your hands from the steering wheel. This is built for drivers who want to feel the road surface through the seat. 

The Verdict for Saudi Buyers

Here are the three things that define the new McLaren 788HS. First, this is the most powerful Super Series car McLaren has built. Second, this has the best power-to-weight ratio of any car on this platform. And last, only 200 will be built. It is not for daily drivers; for those, the brand is expanding into Beyond Supercars: SUVs and Luxury Sedans Incoming. This is built for the buyers who want to add a statement piece to their supercar garage.
