Lotus Ethos

The Lotus Ethos is a fully plug-in hybrid concept car that was unveiled at the 2010 Paris Motor Show as the "Lotus CityCar". The vehicle was developed by Lotus Engineering, a separate division from Lotus Cars. The CityCar has a lithium battery pack with an all-electric range of 60 km, and after the battery is depleted the 1.2-litre petrol engine kicks in to help with charging, allowing the car to run more than 500 km. The concept car is designed for flex-fuel operation on ethanol, or methanol as well as regular petrol.

Specifications
The Ethos concept is an urban electric car with a 14.8 kWh lithium battery pack that delivers a range of up to 37 mi in electric-only mode. The internal combustion engine is a flex-fuel-capable 47 hp, 1.2-litre three-cylinder petrol engine that acts as a generator charging the battery pack up to 310 mi. The concept car weighs less than 1400 kg, and Lotus claims it will reach 62 mph from rest in 9 seconds. Top speed is 170 km/h, with a charge-sustaining top speed of 120 km/h and the drivetrain has CO2 emissions rating below of 60 g/km on the ECE-R101 test.

Naming and production plans
In 2011 Lotus named the concept the Lotus Ethos. It is based on the EMAS from its parent company Proton and was to be assembled in Malaysia alongside the EMAS for an estimated cost in the UK of "£30,000 plus" but never entered production.
