The transfer gearbox in the AWD models — the same as used in the Vauxhall Cavalier AWD—was somewhat on the flimsy side, liable to suffer damage from conditions such as minor differences in tyre wear or tyre pressure between front and rear axles. Since front and rear tyres would naturally wear at different rates in normal driving, it was necessary to swap front with rear tyres every 15,000 miles (24,000 km).
We’ll come back to that in a minute, but first – what is a Crossland X and why is it here? It’s actually Opel’s new small crossover, and also a replacement for the old Meriva MPV, and it shares a chassis and some major mechanical bits with the Peugeot 2008 and Citroen C3 Aircross. Ah, so you’ll assume, this must be the first fruits of the much-bandied-about buyout of Opel by the PSA Group that owns Peugeot and Citroen. Well, not quite. The three car brands actually began collaborating on new chassis and engines some time ago, and the forthcoming Grandland X (Opel’s rival for the Nissan Qashqai) will share its chassis with the Peugeot 3008 and the Citroen C5 Aircross.
The GSi's engine mapping had been carried out by Opel tuning specialists Irmscher. A model with the 82 PS (60 kW) 1.4 L multi point fuel injected engine, which was otherwise mechanically identical to the GSi, also became available as the Nova SRi in the United Kingdom. In January 1988, a turbocharged version of the Isuzu diesel engine was introduced, with power increased to 67 PS (49 kW).
