Fun different from naturally aspirated Porsche
The Porsche 911 Carrera 3.2 SE is always dense. If the tachometer needle is raised sharply, the volume of the tenor increases, and the coupe with the whale tail on its back suddenly increases its speed. The ride is surprisingly supple. The chassis grips the road.
If you handle it too carefully in corners, it will turn to understeer. If you intentionally give the accelerator pedal an angle, you can enjoy the unique maneuverability of turning from the rear axle. It is sucked into the apex of the corner at high speed and fills the driver with a strong sense of unity.

The same goes for the rear-engined Renault Alpine GTA V6 Turbo. A turbocharger adds power to the 2.5L V6 engine, and the steering is sharp. The suspension is tight and you can trace the line as you aim. However, the characteristics are much stronger than the 911 Carrera 3.2.
The 5-speed manual has a long ratio and is suitable for high-speed driving that utilizes thick torque. In winding where you want to suppress understeer, it is necessary to anticipate the increase in boost pressure. Even with the same RR, there is a different enjoyment from the naturally aspirated Porsche.
As the modern styling by Yves Regal, the designer who also worked on the Renault 5 Turbo, evokes, it runs comfortably on the highway. With a discreet roar from behind the driver.
Air resistance is surprisingly low, with a Cd value of 0.28 for the naturally aspirated GTA. The GTA V6 turbo, which added intake items, increased to 0.30, but the 911 at the same time was 0.39.
Impression that seems to be a junior supercar
The interior was designed by Marcello Gandini. The leather-covered seats are luxurious, and the cassette tape stereo unit has a 5-range equalizer. As a rival of the 911 Carrera 3.2, it is not inferior both inside and outside.
Underneath its sleek exterior hides an updated 1971 coupe A310 chassis. Like the Alpine before it, the FRP body was glued to the steel structure.

Compared to the A310, the engine mounting position is shifted 40mm forward. The front/rear weight distribution was 38.1:61.9, which was slightly improved.
Both the front and rear suspensions are double wishbone suspensions with an anti-dive design, and the dampers are exclusive. The tire size is 195/50 at the front and 225/50 at the rear, giving the impression of a junior supercar.
The PRV V6 engine jointly developed by Peugeot, Renault and Volvo on the rear is also inherited from the previous generation. Even so, Renault proceeded with development with the aim of competing on an equal footing with sports cars such as Porsche, whose performance was advancing.
In fact, the avant-garde looking Alpine GTA V6 Turbo had become an important model for the company, thanks in part to its motorsport achievements and the technical reputation it had built up over the years. Alongside the Renault 25 Turbo, a 5-door hatchback with the same engine.
The Alpine GTA V6 turbo is equipped with an intercooler in the 2.5L PRV unit. The intake and exhaust were originally designed, fuel injection was given, and 18ps and 0.4kg-m were increased from the 25 turbo.
As a 2+2 coupe, a moving experience with little dissatisfaction
