The 1000 was the first 4 cylinder NSU, and it had a slightly longer sibling with which it shared body and drivetrain (with minor differences) from the A-Pillar and back - the Typ110 (1.1 litre engine), which later became the 1200 (1.2 litre). Sport-racing versions of the 1000 included the TT (1.2 litre engine of the 1200) and TTS (tuned 1.0 litre engine with double the output of the base 1000).
All had a rear-mounted transverse 4 cylinder, air cooled, chain-driven single overhead camshaft engine. Front suspension was double wishbone with coil springs and rear suspension was semi-trailing arms with coil springs.
Rear suspension was common for all models, front suspension in the Typ110 and 1200 was improved with more travel and better ride. 1000 had a shorter wheelbase and front "boot" and less legroom up front.
Probably the best handling and most sporty rear engined sedans of the period, as well as having the best packaging (usable space vs. overall size). Most common reliability problems were tendency to burn valves under prolonged hard running, and 6 volt electrical system in the 1000.
