BRITISH HEROES McLAREN P1 GTR Tweaked for speed Centre-lock wheels mount to beefy GT3-style uprights. Wishbones are P1 but suspension ditches rubber bushes for pin bearings, to better cope with the increased cornering loads. Bodywork is stretched over a 30mm wider track. Screen excepted, carbon and polycarbonate replace heavy glass. Full of fluids P1 GTR carries 35 litres of coolant for the engine and electrical systems. P1’s aluminium fuel tank is replaced by a 57-litre bag-type tank in a carbonfibre box, fed by a race-style filler under a hatch in the roof. Still not sold? The clever stuff to help swing the £1.98million decision Formula E power The P1 GTR’s electric motor is an uprated unit closely related to the one used in Formula E’s single-seaters. It boasts improved cooling over the standard P1 motor and reduced frictional losses to deliver a shaft output of 147kW. Crucially the P1 GTR will see off a lesser P1 easily in an E-mode race… A little bit of F1 The interior door release catches are the same as those used in the F1 to open the luggage compartments. Trick transmission Ratios are as per the P1 – ‘It’s got so much torque there was no point changing them,’ explains development engineer James Hebditch. ‘For durability the pinion gear is coated in Balinit C and the gearbox uses a higher-spec lubricant.’ Produced 2014-2015 Price at launch £1.98 million Engine 3799cc twin-turbocharged V8 with 147kW e-motor, 986bhp, 738lb ft Performance 2.7sec 0-62mph (est), 202mph Keeping its cool Coolant is pumped through a honeycomb structure within the batteries. Fed by a low-temperature circuit linked to the vast central radiator in the GTR’s nose, the cells are kept as close as possible to room temperature – difficult when the GTR uses powerhungry Charge mode as a matter of course and is set to run at circuits like Yas Marina. Beyond 50°C power is reduced to save the cells. 986bhp and mighty grip, but the GTR’s biggest win is giving you the confidence to play <strong>September</strong> 2015 | CARMAGAZINE.CO.UK 119
