Engine. This is the FIRE 1000 engine with the power output raised from 45 to 50 bhp at 5500 rpm. The maximum torque is 8 MKG at 3000 rpm with the very flat torque curve desirable for 4x4 driving. The ignition is of the electronic breakerless type.

Gear Ratios. The selection of the correct gear ratio is vital for a car that has to operate as a 4x4 and tackle difficult road conditions. The Y10 4WD has a shorter final drive than the front wheel drive Y10 Fire (5.455:1 as against 3.733:1) while 5th gear is longer (0.73:1 as against 0.78:1), the remaining gear ratios being unchanged. This makes for improved pick up in 1st gear, extra sparkle in the middle ratios and a top speed of 145 kph (as with the Y10 Fire) but achieved in 5th rather than 4th gear.

Suspension. The classic Y10 Omega suspension has been replaced by a rigid rear axle with longitudinal leaf springs in order to accept the four wheel drive components.
