Introduced mid-year in 1992 as a 1993 model. Displacement was increased again to 5.4 liters yielding the most powerful 928 engine from Porsche - 345HP. Recall that the original 928 engine was designed back in 1971 to accomodate 5.5 liters from the factory - so at model year 1993 there still remained one more displacement increase. If only production had not stopped in 1995! 

The 928 GTS is essentially a further hotted-up version of the '91 - '92 928 GT (note 1), however the shock valving was softened up to provide a more compliant ride. Both the manual and automatic transaxles were refined to handle the GTS' increased power outputs. Rear fenders had integrated flares for a 2.7" wider track (note 1) as the wheel size was now 17 x 9 inches running 255/40 ZR 17's (fronts 225/45 ZR 17's).

A reflective strip was mounted between the tailights which visually reduced the size of the rear fascia as well as provided for an extra safety margain in visibilty for following drivers. 

The Porsche electronically controlled limited-slip continues, as well the ABS option. Brakes were upgraded to a massive 12.68 inches vs. 11.97 previously. Brembo 4-piston calipers squeeze those rotors with authority and the entire setup is coined 'GTS brakes' by enthusiasts - many of whom are busy upgrading their earlier cars to this standard. 

The 928 GTS represents the pinnacle of the 928 series and garners respect in automotive circles worldwide. Price: $80,920.00 (note 1)
