The big news from an EV front is that from 2016, the 3 Series range will also include the 330e plug-in hybrid, designed to rival the Mercedes hybrid option offers on the C-Class. According to BMW, the maximum output of the 330e’s hybrid drivetrain is pegged at 185 kW (252 hp). Both Mercedes and BMW claim fuel economy of 2.1 l/100km (112 mpg) for their hybrids, while the BMW will travel 35 km (22 miles) on battery power alone – 4 km (2.5 miles) more than the C350 plug-in hybrid can manage.
It’s expected the model will use the new four-cylinder-based drivetrain that was shown in the concept X5 EDrive shown at last September’s Frankfurt show. This means the car will primarily be powered by a four-cylinder turbocharged petrol engine, in conjunction with a 95bhp electric motor and lithium-ion battery pack.
Judging by the claims BMW has made for the rather larger and heavier X5 plug-in, the new 3-series should be able to cover over 25 miles on pure battery power at speeds of up to 75mph. This 3-series is likely to be given an official consumption figure of over 80mpg when it undergoes EU fuel consumption tests.
The car will have switchable driving modes, and will default into EcoPro mode when the car starts up. BMW says this offers “intelligent hybrid functionality, whereby the energy management system tailors the interplay of combustion engine and electric drive system to most efficient effect.” A fully charged battery pack can also be put into ‘hold’ mode, so drivers can utilise emissions-free driving, for example, at their city-centre destination.
BMW says the new plug-in drivetrain means that “drivers can also enjoy the services of the hybrid-specific Proactive Driving Assistant, which teams up with the navigation system to incorporate factors such as route profile, speed restrictions and the traffic situation into the driving mode selection”.
We are looking forward to our test drive and expect the fact that BMW is introducing a Plug In in the extremely popular 3 series is a big plus for the EV world.
