Some Interesting Porsche 928 GTS Facts

Final Evolution of the Porsche 928
The Porsche 928 GTS, produced from 1992 to 1995, was the last and most powerful version of the 928 grand tourer, which originally debuted in 1977.
Most Powerful 928 Model
It was powered by a 5.4-liter naturally aspirated V8, producing 350 horsepower (257 kW) and 500 Nm (369 lb-ft) of torque, making it the most powerful factory 928 ever built.
Front-Engine V8 Grand Tourer
Unlike most Porsches, the 928 GTS had a front-mounted V8, paired with a rear-mounted transaxle for perfect 50/50 weight distribution, improving handling.
Available with a Manual or Automatic Transmission
The 928 GTS was offered with either a 5-speed manual gearbox or a 4-speed automatic, though the majority were sold with the automatic.
Distinctive Wide-Body Design
The GTS featured wider rear fenders, giving it a more aggressive stance compared to earlier 928 models.
Signature Rear Light Bar
The continuous rear light strip, connecting the taillights, became a signature design element that influenced future Porsche models like the 992-generation 911.
One of the Most Expensive Porsches of its Time
The 928 GTS was more expensive than a 911 in the early 1990s, making it a high-end luxury GT car rather than a lightweight sports car.
Highly Comfortable and Technologically Advanced
The 928 GTS featured luxury touches like power-adjustable leather seats, an advanced climate control system, and improved sound insulation, making it a true grand tourer.
Originally Designed to Replace the 911
Porsche originally intended the 928 to replace the 911, believing that front-engine V8 cars would be the future, but the 911’s popularity ensured its survival.
Now a Highly Collectible Classic
Due to its low production numbers, final edition status, and naturally aspirated V8, the 928 GTS has become a highly sought-after collector’s car, with values rising significantly in recent years.
