Apart from the awesome five Lotus unveiled at the start of this year's Paris Motor Show, the "boutique automaker" has now introduced a City Car concept that caters to urban driving and eco friendliness.
The 3-door 4-seater compact car weighs in at a very un-Lotus like 1,400kg, and is fitted with a front-mounted petrol engine coupled to a rear-mounted electric motor that powers the rear axle. The battery for the motor is fitted underneath the passenger compartment.
Though the continuos power figure is a modest 70hp, the total power output from the hybrid system stands at a very impressive 218hp and 240Nm of torque. The electric motor provided a range of 60km on electric power alone while the 44hp 1.2-liter range extending engine takes the figure up to 500km. The engine is a flex-fuel power plant that is able to run on ethanol and methanol and produces power for the electric motor alone and does not drive the car on its own, making this City Concept a rear wheel drive unit.
The rear wheel drive layout could provide for plenty of fun, but the 0-100km/h sprint stands at 9 seconds, fairly reasonable for a car that is made for city driving rather than spending time going sideways through bends. And just to help keep your conscious clear, the car emits zero emissions when running on EV and exactly, and a very green, 60 g/km of CO2.
Malaysian car fans may be familiar with the design of the car, first previewed as the Proton Emas, and features a glass roof, cabin wrapped in typical Lotus green and yellow tartan fabric, as well as some leather and carbon fiber touches.
Lotus Chief Engineer, Wolf Zimmerman, has said that Lotus wants a city car similar to the Aston Martin Cygnet and is looking for a strategic partner to produce the city car for a 2014 launch.
"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 that is posted below for you to refer to for more information.
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."
