The fact that this car is not very economical, may be recognizable by the (for the time) unusually large tank. This characteristic and its more than average harmful emissions are also a burden to the car until its last day. In the course of the years, NSU is successful in removing its childhood illnesses. A long-lasting sealing between rotary piston and trochoid housing and a better coating of the running surface increase the very low durability of the engine almost to normal values. The engine still does not appreciate a sequence of short distances.

Also the lubricating oil consumption can be regulated. The Wankel engine is lubricated by a mixture of oil and fuel as well as by pressure lubrication. The first series consumes quite a lot of oil. Improved sealing between the internal oil space and the chamber volume also provide for relatively little oil ejection after a longer stand still. Learn more about the engine here.

The car features a modern, beautiful car body which should have yielded a higher number of sales figures. The low engine enables a smoothly rising bonnet. The large and just slightly sloping windscreen is ahead of its time. The interior is relatively limited, though. This holds true also for the road performances and especially the acceleration.

Positively are the external appearance of the car, and the large wheel base, in spite of its longitudinal engine and front-wheel drive. The car drives smoothly and has a high comfort. Why did not they establish this car also with a conventional engine? Enhancing comfort and sport unsuitable is to the semi-automatic. A bit unusual for the front-wheel drive are the rear semi-trailing arms. For increased security requirements, there is a 4x2 dual-circuit brake with two brake hoses to each front wheel.               Top of page               Index
