 Lotus City Car Concept revealed - aims to reduce fleet CO2 emissions
Lotus City Car Concept 05.10.2010

Total power output on the City Car is a hefty 162 kW (220 PS) and 240 Nm of torque

Lotus has introduced the City Car concept with which the boutique automaker hopes to gain some urban-driving/planet-friendly credibility.

The Lotus City Car is a 1,400 kg (3,086 lb), 3-door, 4-seat compact car with a front-mounted, range-extending gasoline engine and a rear-mounted electric motor powering the rear axle. The battery is fitted underneath the passenger compartment.

Total power output on the City Car is a hefty 162 kW (220 PS) and 240 Nm of torque - although the continuous power figure is a more modest 54 kW (73 PS). Range on electric power alone is 60 km (37 mi) while the range-extending 34 kW (46 PS) 1.2 liter petrol/gasoline engine, which is a flex-fuel power plant that can also run on ethanol and methanol, takes that figure to a sounder 500 km (311 mi). The engine produces power for the electric motor alone and doesn't drive the car on its own.

The 0 to 100 km/h sprint takes a reasonable 9 seconds. For city driving, which these plug-in hybrids are made for, the 0 to 50 km/h (31 mph) figure is often cited and for the Lotus City car it's exactly half - 4.5 seconds. CO2 emissions are a very green 60 g/km on the total cycle but are zero if the car is run solely as city-prowling EV.

Design-wise the City Car features a glass roof, cabin upholstery in a prime green and yellow tartan fabric, as well as leather and carbon fiber touches.

Wolf Zimmerman, Lotus' chief engineer, told Autocar that Lotus is looking for a partner to produce the city car for a 2014 launch. Zimmerman also said the company wanted to have a city car similar to the Aston Martin Cygnet.

"Lotus Design has created a vehicle that condenses the essence of Lotus into a low carbon city car, with many inspired design touches," said Dany Bahar, Group Lotus CEO, in a company press release.

Making its debut at the Paris Motorshow 2010, the Lotus City Car concept expertly blends the latest Lotus Engineering series hybrid drivetrain technology with Lotus Design sophistication.

The Lotus City Car concept provides a showcase for Lotus Engineering's Electrical and Electronic Integration and Efficient Performance competencies, featuring an advanced series hybrid drivetrain with the Lotus Range Extender engine. This innovative concept car highlights the adaptability of the drivetrain technology and the exceptional capability of Lotus Design.

Advanced hybrid technology from Lotus Engineering

The City Car concept features a Lotus Engineering designed and integrated series hybrid drivetrain, with a single-speed transmission that delivers low emissions, optimised performance and electric-only operating range for city use.

The drivetrain provides the vehicle with an EV range of 60 km to cover the majority of daily journeys operating as a plug-in EV, with the Range Extender engine enabling longer trips and alleviating "range anxiety". Using Range Extender technology allows the vehicle to be specified with a smaller, lighter and less expensive battery pack than a regular EV.

The 500 km full range and quick refuelling capability of the range extended City Car concept highlight the flexibility of this technology for use beyond the city environment. The City Car concept draws on Lotus Engineering's established core competencies of Electrical and Electronic Integration and Efficient Performance to optimise the highly complex integration of the series hybrid drivetrain.

With a total vehicle weight of less than 1400 kg and 240 Nm of torque instantly available, the Lotus City Car concept has class leading acceleration; 0 - 50 km/h in only 4.5 seconds and 0 - 100 km/h in 9 seconds, when operating as an EV under battery power. The top speed of the Lotus City Car concept is 170 km/h, with a charge sustaining top speed of 120 km/h and all this performance is achieved by a drivetrain that returns CO2 emissions of 60 g/km on the ECE-R101 test schedule.

The 1.2 litre, 3 cylinder Lotus Range Extender engine, specifically designed for hybrid vehicle applications, drives a 240 Nm, 54 kW continuous (162 kW peak) generator. The Lotus City Car concept boasts zero emission capability when running in EV mode and in keeping with Lotus Engineering's focus on sustainable transport, the Range Extender engine is designed for flex-fuel operation on ethanol and methanol as well as regular gasoline.

Exclusive Lotus Design

This stunning concept car created by Lotus Design brings Lotus exclusivity and brand character to a concept vehicle that revels in the city environment. It is beautifully sculptured, possessing a solid, purposeful sportscar stance, while offering features that maximise functionality in the city.
With its chic body and overtly sporty nature, the Lotus City Car concept exudes style and sophistication. The distinctive Lotus mouth and diffuser give the car purpose, with the wide track, low ride height and big wheels reinforcing the sportcar styling.

The design features an impressive use of space with very efficient packaging constrained within the compact vehicle dimensions. The Lotus City Car concept provides enhanced visibility for the driver and low emissions to optimise use in urban life.

A dramatic glass roof is incorporated into the design to further increase visibility; under the glass roof the interior is upholstered in a luxuriant green and yellow tartan fabric and immaculately finished with a technologically advanced Lotus steering wheel. The high specification of the Lotus City Car concept is emphasised by the mix of carbon fibre, sumptuous leather and high quality equipment.

Dany Bahar, Chief Executive Officer of Group Lotus said, "Lotus Design has created a vehicle that condenses the essence of Lotus into a low carbon city car, with many inspired design touches. The progressive technology from Lotus Engineering gives the car an advanced drivetrain that can be operated in Zero Emissions EV mode or run on its flex-fuel engine."

Adding "As you would expect from Lotus, the City Car concept is an exquisitely designed, highly efficient vehicle with class leading performance - in this concept car, Lotus Design and Lotus Engineering have provided the perfect solution for life in the contemporary city environment."

Lotus new business direction just keeps getting better and better. It is quite heavy at 1.4 tonnes, but at least it has alot of power, so I'm happy with it.

Love this car! Hoping it's priced well below ?20k and makes production. And since was Lotus only known for the Elise? Never heard of the Seven, Elan, Esprit or three F1 constructors championships?

First we see 5 cars that completely ignore the basic foundation of Lotus, and now this heavy, uninteresting citybox. Why did it all have to go so wrong so quickly Lotus? Why?

I like Lotus' new direction. I always wanted to like Lotus, I just didn't agree with their no compromise lightweight philosophy. They can keep making that Elise and Exige and what have you, but now I can walk into a Lotus dealership knowing I can drive out with something more for me.

I'm on your side Mikeado. I understand the need for Lotus to produce cars more focused to the streets, and the current Evora is already soft enough, striking a good balance on comfort and Colin Chapman's lightweight principle, but cars like the concept above just went a little too far in my opinion. I really do wish to see ultra-light city cars, possibly still with a hybrid drivetrain, but using capacitors instead of batteries to cut weight and to suit the quick charge-and-discharge drivings around cities. Anyway, no offence to Lotus.

That box has 1.5T of weight. At least 66g/km for electricity in our plugs + combustion engine at least 90g/km +... so buy a BMW.
