Oohhh! I just love this type of weird and wonderful vehicles.
" In 1971, production of three-wheeled cars stopped, and the company switched to production of a four-wheeler, the “Model 435-0”, which featured the Jawa 350 type 572 - 04 engine. Problems in design and manufacturing, as well as the inability to compete with higher-category cars (including the cheap Trabants), made the four-wheeler a commercial failure, and its production was stopped in 1973."
“higher-category cars (including the cheap Trabants)”
You really know your place in the relative hierarchy or luxury cars when a Trabant is higher up the ladder than yourself.
Shiver in fear ye Maseratis, Lamborghinis, Ferraris and other toys for the rich because here I come, packing a whopping handful of horsepowers. I’ll chase y’all down the highways at the lightning speeds of 30 km/h (18.64 mph)
For reference, the Trabant could reach a whopping 105 km/h (65 mph), 3.5 times faster than the Velorex 3-wheeler, the four wheel Trabant killer could hit 80 km/h (49.7 mph)
so it was only 25 km/h (15.5 mph) slower than the Trabant.
