BMW i8 uses a plug-in hybrid system consisting of a turbocharged three-cylinder BMW TwinPower Turbo petrol engine and BMW eDrive technology in the form of an electric drive system. The 1.5-liter combustion engine develops 170 kW/231 hp and drives the rear wheels of the BMW i8, while the 96 kW/131 hp electric drive sends its power to the front wheels and allows an all-electric range of up to 35 kilometers (22 miles) and a top speed of 120 km/h (75 mph).
That top speed is using JUST the electric engine, and the total combined power is 360HP. Not sure of the top speed or 0-60 but i'm pretty sure this is supposed to be a sports car so it won't be slow.Looks a bit chav if I am totally honest. But then if it has the performance to match (I have no idea what the performance is) then it can get away with it.
Edit: perhaps not.
If the motor is 131hp, then why can it only go 75mph?
Fair point, I read it as top speed, not top speed before the engine comes on.[TW]Fox;25881071 said:It cant, it can do 155 but 75 is the speed at which the petrol engine kicks in to assist.
Not really the same at all the way I see it, the McLaren system augments the engines torque by adding more directly into the flywheel, this cars electric system is a completely separate drive not even working on the same axle.Fairly sure the electric motor will work in unison with the petrol engine to fill in the torque gaps like the Mclaren video Chris Harris just did, the electric motor will be working almost constantly to help provide seemless torque everywhere.
If the motor is 131hp, then why can it only go 75mph?
Is this a bit like a Lexus GS450h then? A proper engine but with an electric one to assist? Because when that works in that way it makes a silly humming noise at all speeds (so I have been told, can't find one to test drive down here).
Except the BMW gets a 3 cylinder 1.5L engine instead of a 3.5litre v6...
[TW]Fox;25881800 said:BMW's equivilent to the GS450H is the ActiveHybrid5. It gets a 3 litre turbocharged straight six.
Actually the torque converter gets taken out and replaced with a clutch pack either side of the e motor. So it's not quite a 'proper' auto, it will be the 8HP75PH in the X5 I guess. Better than the Lexus /Toyota power split device with the infinite ratio aspect.
