New McLaren Senna hypercar will hit 0-62mph in 2.8 seconds

By Paul Connolly

McLaren has released eagerly-awaited new technical data about its Senna hypercar, revealing the track-focused monster can hit 62mph from a standing start in 2.8 seconds.

Ahead of its 6 March launch at the Geneva Motor Show, the UK-based manufacturer has laid out a wealth of performance and other data for the car, inspired by F1 legend Ayrton Senna.

The Senna combines low vehicle weight, extreme power, aerodynamic excellence and a revolutionary, active suspension system to deliver what is being trumpeted as the “most responsive and engaging road car experience to date” from the British luxury sportscar and supercar maker.

Amongst the new details revealed are:

  • Maximum speed of 211mph (340km/h)
  • 0-62mph in 2.8 seconds
  • Body design, rear wing and active aero front and rear are key to generating 800kg of downforce at 155mph
  • Acceleration from 0-200kmh (124mph) in 6.8 seconds
  • Weight: 1,198kg
  • Power-to-weight ratio of 668PS (659bhp) per tonne
  • Production limited to 500 units, all hand-assembled at the McLaren centre in Woking in a 300-hour process

The 2.8 seconds time for 0-62mph makes the Senna one of the world’s quickest cars.

The world’s fastest petrol engine production car is said to be the Bugatti Chiron with a 0-62mph speed of 2.5 seconds, according to manufacturer data.

The world’s fastest car (also as measured by manufacturer data) is the Tesla Model S P100D with Ludicrous+ update; it has an official 0-62mph time of 2.4 seconds.

Anyone with £750,000 who wants to buy a McLaren Senna will be disappointed: they are already all sold.

Key to the lightness of the car is the carbon fibre Monocage III chassis and carbon fibre body panels integral, which make it the lightest road car McLaren has built since the iconic F1.

The Senna is driven by a 4.0-litre, twin-turbocharged V8 – McLaren’ s most powerful-ever internal combustion engine in a road car.

McLaren boss Mike Flewitt said: “The McLaren Senna is a car like no other: the personification of McLaren’s motorsport DNA, legalised for road use but designed and developed from the outset to excel on a circuit.

“Every element of this new Ultimate Series McLaren has an uncompromised performance focus, honed to ensure the purest possible connection between driver and machine and deliver the ultimate track driving experience in the way that only a McLaren can.”

McLaren also revealed the twin-turbocharged V8 engine, which is coded M840TR, features a flat-plane crankshaft, race-inspired dry sump lubrication and lightweight connecting rods and pistons that reduce mass in the powertrain.

Ultra-low inertia twin-scroll turbochargers and electronically-controlled wastegates give an immediate sense of retardation, enhancing engine responsiveness.

Lightweight camshafts and pistons unique to the McLaren Senna and externally repositioned dump valves are among other Senna-specific components. 

Stats unveiled show the engine produces 700Nm (516lb ft) from just 3,000rpm, with peak torque of 800Nm (590lb ft) available from 5,500-6,700rpm. 800PS (789bhp) peak power comes at 7,250rpm.

A dual-clutch, seven-speed gearbox delivers power to the rear wheels.

The default transmission mode is fully automatic, but a McLaren Senna driver can select full manual control of gear shifts via the Active Dynamics Panel located within the centrally-mounted screen and change gear using elongated, carbon fibre paddles mounted on a rocker behind the steering wheel.  The paddles are optimised to be used both with or without racing gloves.

Ayrton Senna’s nephew Bruno Senna, also a racing driver, said: “The McLaren Senna honours my uncle because it is so utterly focused upon the driver, and their absolute connection with the vehicle.

“This engagement, these sensory cues that the driver responds to and relies upon, the whole immersive experience, has been at the heart of the development from the very start.”
