The McLaren Speedtail Has 308 HP Of Electric Power And A 746 HP V8

A number of additional details about the McLaren Speedtail have been announced before the hypercar makes its public debut at the Geneva Motor Show.

Road & Track reports that prior to the show getting underway, McLaren vehicle line boss for the Ultimate Series, Andy Palmer, revealed to select members of the motoring press some tidbits about the second three-seater, after the iconic F1, in the company’s history.

Let’s start with the powertrain. McLaren previously announced the Speedtail had 1035 hp and 848 lb-ft (1149 Nm) from a hybrid system. Now, we have learned that its twin-turbo 4.0-liter V8 provides 746 hp and 590 lb-ft (799 Nm) while a powerful electric motor offers up an additional 308 hp and 256 lb-ft (347 Nm). The internal combustion engine and electric motor provide peak power at different points, which is why the combined figure isn’t 1054 hp.

The 4.0-liiter twin-turbo V8 found beneath the sleek bodywork of the Speedtail is related to the unit found in the 720S and Senna, but it’s been modified to accommodate the electric motor.

This electric motor acts directly on the input shaft of the seven-speed Graziano dual-clutch transmission, meaning the Speedtail can’t be driven in EV-only mode like the McLaren P1. Powering the electric motor is a 115 lb (52 kg) battery located beneath the fuel tank, while a wireless charger is also found on the underside of the front bumper.

The Speedtail has an impressively low dry weight of 3,153 lbs (1,430 kg), making it heavier than the 720S (2,829 lbs / 1,283 kg) but lighter than the 3,197 lb (1,450 kg) P1.

Production of the McLaren Speedtail will start at the end of 2019. Prices started at £1.75 million ($2.3 million) and all 106 cars bound for production have already been spoken for.
