Gordon Murray Design has announced that the projected emissions for its electric T.27 City Car will be 48 g/km CO2 for the combined cycle, based on using electricity from a mixed UK energy supply.
Emissions will be 28 g/km CO2 for the urban cycle, although they will obviously be zero at the point of use. Full lifecycle CO2 damage will be 42% less than the average UK car.
The T.27 City Car is a pure electric drive vehicle designed to fully optimise packaging, weight and performance.
The marks a leap forward in efficiency for electric vehicles. Working closely with its powertrain partner Zytek Automotive, a brand new, innovative, lightweight and fully integrated electric motor, control system and battery will be designed to ensure that maximum efficiency is achieved.
The T.27 will have a 12kWh lithium-ion battery, with a 25kW electric motor. A key element of the overall car is its light weight, which will be just 680 Kg (including battery). It’s expected to have a top speed of around 65 mph with a range of 80-100 miles.
The T.27 vehicle concept closely follows the layout and geometry of Gordon Murray Design’s T.25 city car, an MPV with 6 possible internal layouts.
The efficiency in cost, weight and performance comes in part from the ‘clean sheet of paper’ approach, part from the full integration of the powertrain, and also from the low energy manufacturing system developed by Gordon Murray Design called iStream.
iStream massively reduces the capital investment required to produce the vehicle and also the energy required for manufacture. The flexibility of the iStream process would also allow the petrol powered T.25 and the T.27 to be manufactured at the same plant.
The 16 month programme started in November 2009 with a running prototype scheduled for completion in April 2011. It is supported with a 50% investment from the Technology Strategy Board. The next phase in the programme will include a push to secure partners and funding for UK manufacture. A UK partner or consortium to produce the city cars in the UK would keep the technology at home and could create 6,000 jobs.
