A further refinement to the facelift range was via the two GX models, with a 3 mm wider bore in the throttle body (increased from 60 mm to 63 mm and mated to the plenum bore), helping to provide the additional 10 PS over the earlier GR model engine. Whilst the GR model continued to offer only 4-speed auto and 5-speed manual into the "facelift" era, the GX Sport and GX Sport Aero upgrade came either as 5-speed manual or 5-speed auto. On the GS and GR models aircon operation became manual from Feb 1997.
