The Lotus Ethos will be based on the same platform as the Proton EMAS Concept, featuring a distinctive Lotus body in tune with the latest Lotus design language - expected to showcase a similar layout to the City Car Concept, pictured.
Lotus spokesman Alastair Florance says the Ethos will not simply be a re-badged Proton:
"We’ll work extensively on the engineering – the Lotus version will be very much a Lotus. But I believe there will be a Proton version."
Like the Proton EMAS, the Ethos will be just 3.5 metres in length, which will make it slightly larger than its main rivals such as the Aston Martin Cygnet and Toyota iQ.
The Ethos will likely be powered by a similar powertrain to the City Car Concept. This means it will use a 1.2-litre three-cylinder range-extending petrol engine matched to an electric system.
The Ethos will reportedly be capable of driving on electricity alone, providing a range of up to 60km. Using the range-extending engine, the Ethos is said to be capable of 500km.
The Lotus Ethos is scheduled to hit the market sometime in 2013.
