OPEL TWIN Gasoline or Propulsion Design Study

At the 1992 Geneva Motor Opel has introduced the TWIN, a new concept for a compact vehicle of the This Corsa-sized model is for a variety of technical innovations. A feature of the Opel TWIN interchangeable drive module engine/motors, transmission and rear

The whole drive-train is combined in a interchangeable module. There are two modules that can be installed at the of the car in just a few minutes, enabling the to select the propulsion method is most economical and environmentally-compatible for his journey. The selection include a 34 kW three cylinder gasoline with transmission and fuel or an electric module with two 10 hp motors and storage batteries.

This innovative modular makes a completely new automobile possible with a “passenger providing and original seating the driver seat occupies an and central position while a seat is available for three passengers. The luggage space this bench has the same as that of a conventional car of this

The original Opel TWIN is a model for demonstration of the project. intended to test the public’s to this new vehicle concept. plan was to examine any noteworthy put forward by members of the public and develop a road-going prototype of design study.

As of today, only the scale-model is to exist.


The TWIN is an example of how engineers are working on reducing consumption and carbon dioxide The gasoline engine module is for a consumption of 3,5 litre per 100 km. It combines an 800 cc. cylinder engine with valves per cylinder fitted a six-speed automatic transmission.

The low objective was to be achieved by using materials as well as optimized efficiency and low rolling resistance tyres.

The gasoline engine is on its side in the drive module to height to a minimum.

An automatic system helps to cut fuel in urban traffic.

With this drive acceleration from 0 to 100 kph (62 mph) is in 20 seconds and the maximum speed is for 140 kph (87 mph); The TWIN can travel an distance of 571 kilometres (354

When designing the interchangeable module for the TWIN, Opel were able to draw on of experience in developing electrically-driven such as Impuls I and Impuls II were essentially production converted to electric propulsion. In the they aim to use wheel-hub motors of compact design. This with additional drive such as the differential and half-shafts: of the two motors drives its wheel at a constant ratio of 7:1.

An electronic power system, comprising two components, controls the driveline.

Each three-phase motor develops 10 kW/14 hp. torque is 24 Newton-meters. The electric accelerates from 0 to 50 kph in seven and reaches a maximum speed of 120 kph.

Energy consumption at a speed of 90 kph is calculated in the region of kWh per 100 kilometres.

The 250 kilogram battery is the of the electric module. Opel plan to use a new kind of “cold” battery which was under and was expected to be available for series by the mid-1990s. This battery on a lithium-carbon base with an density around 200 watt per litre.

The energy store for use in the electric module of TWIN vehicle measures 145 litres in and weighs 290 kilograms. Its energy is equal to 29 kilowatt hours, makes this electric average range about 250

When designing the interior of the Opel attached the greatest to ride comfort and operating To make it easy for the driver to get in and out of the seat position, the single seat is moved forwards and to the by electric motors. It also so that the driver can turn to the rear seat passengers the car is stationary.

Passengers are carried in on a well upholstered rear seat, the outside sections of are fitted with fold-down

The scale model demonstration design study was unfortunately not officially by a running prototype. make it so that most and performances figures are calculated values.
