Lotus Ethos "CityCar" Concept
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 kilometres (37 mi), and after the battery is depleted the 1.2-liter petrol engine kicks in to help with charging, allowing the car to run more than 500 kilometres (310 mi). The concept car is designed for flex-fuel operation on ethanol, or methanol as well as regular petrol.
The Ethos concept is an urban electric car with a 14.8-kWh lithium battery pack that delivers a range of up to 37 miles (60 km) in electric-only mode. The internal combustion engine is a flex-fuel-capable 47 hp, 1.2 liter three-cylinder petrol engine that acts as a generator charging the battery pack up to 310 miles (500 km) miles. The concept car weighs less than 1400 kg and Lotus claims it will reach 62 miles per hour (100 km/h) from rest in 9 seconds. Top speed is 170 kilometres per hour (110 mph), with a charge-sustaining top speed of 120 kilometres per hour (75 mph) and the drivetrain has CO2 emissions rating below of 60 g/km on the ECE-R101 test.
