Honda already announced that it will resume F1 partnership with McLaren in 2015, when the Japanese manufacturer will provide engines to the British team. However, it appears that the collaboration will be limited to the motorsport world as Jolyon Nash a.k.a. McLaren’s director for global sales and marketing said that we will see no Honda engines on McLaren’s road cars.
Nash also added that McLaren is an independent company and that they don’t need to go into a partnership with another manufacturer. Former McLaren designer Gordon Murray asked Honda to provide power for the McLaren F1, before choosing the 6.1-liter V12 built by BMW.
Moreover, the McLaren-Mercedes SLR featured a V8 engine built by Mercedes-Benz. Currently, McLaren uses the same 3.8-liter twin-turbo V8 engine on all of its models and as expected, the most powerful version is found on the P1 hypercar.
On the McLaren P1, the 3.8-liter twin-turbo V8 engine delivers 737 hp and 720 Nm of torque, but it is also helped by an electric motor producing 179 hp and 260 Nm.
The total output delivered by the hybrid system is 916 hp and as a result, the P1 is able to accelerate from 0 to 100 km/h (62 mph) in less than 3 seconds, to 200 km/h (124 mph) in under 7 seconds and to 300 km/h (62 mph) in no more than 17 seconds. Top speed is limited at 350 km/h or 217 mph. [source: drive.com.au]
