Car and Driver said "It isn't really a coupe, but this 541-hp fastback SUV is the same awesome Cayenne Turbo underneath—with a sexier backside". We agree. Here's what you need to know. With its 541-hp twin-turbo 4.0-liter V-8, eight-speed automatic transmission, and all-wheel drive, the new fastback version of Porsche's largest SUV is mechanically identical to the conventional Cayenne Turbo SUV, and the two vehicles feel exactly the same from behind the wheel.
Its top model was the Cayenne Turbo, with 550 hp under the hood. The third generation came to fix what its predecessor was criticized for: the exterior design. While the second generation featured some details that could remind of a Hyundai, the third generation was completely new from tip to toe. Under the hood, the Cayenne Turbo featured a 4.0-liter V8 unit with two turbochargers. It was mated as standard to an eight-speed automatic transmission.
The second generation of the Porsche Cayenne was launched at the 2010 Geneva Motor Show. It was a big improvement over its predecessor and featured an evolved design. For the engine, the Cayenne Turbo featured a 4.8-liter V8 unit which offered 500 hp. For the transmission, the 2010 Cayenne lost the low-range transfer case. The standard transmission was an 8-speed Tiptronic gearbox. All-wheel drive was installed standard as well. Other new improvements led to a decrease in the overall weight by 180 kg (400 lbs).
The Cayenne Turbo facelift was introduced in 2014 as a 2015 MY. Think of it as an enhanced version of the non-facelifted version. It offered the same torque as the non-facelifted Cayenne Turbo S, but less power. Under the hood, the revised engine offered 20 hp more than its predecessor. The exterior of the 2015 Cayenne was enhanced with a sharper design and clear lines. The front fenders, the grille, and the headlights were entirely new, with LEDs.
The facelift for the first generation of the Cayenne was introduced in 2007. More powerful in every respect - that is how the new generation of the Porsche Cayenne entered the market. New striking face upfront on a wide and muscular body, with headlights in brand-new design, and with broader, even more powerful-looking wheel arches. The Turbo model 957, featuring a larger 4.8-L engine with 49 hp more power, 0–60 mph time of just 4.9 seconds.
The first-generation Cayenne Turbo 955 has 450 PS (331 kW), and can accelerate from 0–100 km/h (62 mph) in 5.3 seconds. Under the hood, the Cayenne Turbo was fitted with a turbocharged 4.5-liter V8 unit mated to a standard 6-speed automatic. Thanks to the standard air-suspension, the Turbo version could get up to 28 cm (11”) of ground clearance. The German brand needed a car to sell in volumes and save them from a foreseeable financial collapse. The Cayenne Turbo did just that.
