With production due to begin next month ahead of the first customer deliveries in June, BMW has finalised the specifications for its new i8.
The car’s eDrive plug-in hybrid system is rated at 356 bhp (266 kW / 362 PS) overall and it consists of three elements. Firstly, there’s a 1.5 litre, three-cylinder, turbocharged petrol engine that produces 228 bhp (170 kW / 231 PS) with 320 Nm (236 lb/ft) of torque. Its output is sent to the rear wheels via a six-speed automatic transmission.
Powering the front wheels is a synchronous electric motor which develops up to 128 bhp (96 kW / 131 PS) and 250 Nm (184 lb/ft). The third component is a 5.2 kWh lithium-ion battery pack that can be recharged to 80% capacity in less than two hours using a 3.7 kW / 230V supply.
Running on electric power only, the four-seat i8 is capable of travelling up to 23 miles (37 kilometres). It’s restricted to 75 mph (120 km/h) in this mode, though.
Using all of the available power sources, the top speed rises to an electronically-limited 155 mph (250 km/h) while the 0-62 mph (100 km/h) sprint takes just 4.4 seconds. More importantly, overtaking should be easy as the 50-75 mph (80-120 km/h) increment can be achieved in a mere 2.6 seconds. Such impressive performance partly results from an unladen kerb weight of only 1,485 kg (3,274 lbs) together with a low 0.26 drag coefficient.
The official EU test cycle yields a fuel consumption figure of 134.5 mpg (2.1 l/100 km) with carbon dioxide emissions of 49 g/km. However, given the battery pack’s capability BMW is managing expectations by pointing out that on longer, higher-speed journeys owners should realistically expect to see around 35 mpg (8 l/100km).
In the UK the BMW i8 is priced from £99,895, so it’s definitely not going to be the cheapest route to fuel-efficient motoring.
