In true Porsche GTS spirit, the output of the 2.5-litre, four-cylinder flat ‘boxer’ engine has been increased to 360 bhp courtesy of a new intake system and an optimized turbocharger. These improvements generate 15bhp more power compared with the 718 S model, and up to 35 bhp more power than the prior GTS models. A manual six-speed gearbox is standard, with the Porsche PDK available as an option. Standard equipment includes the Sport Chrono Package, Porsche Torque Vectoring (PTV) with a mechanical rear axle limited slip differential and Porsche Active Suspension Management (PASM).
Porsche 911 Carrera 2 Targa (964) (1990 - 1993)
Like the Carrera 4, the Carrera 2 was available as a coupé, Targa or Cabriolet. This was the last generation Targa with traditional removable Targa roof (till 991). It sold ok, with 3,534 units sold over its lifetime. The engine was the 3.6 liter unit which produced 250 horsepower and a maximum speed of 162 mph while the 0 to 60 mph acceleration was made in about 5.6 seconds. Performance was on par with the coupe and it is the looker in the 964 range.
Porsche 911 Carrera 4 Targa (964) (1990 - 1993)
This was the last generation Targa with traditional removable Targa roof (till 991). The Carrera 4 Targa outsold the Carrera 2 Targa by 2x, making the 4 Targa much rarer and more collectible. In all, only 1,329 units were made. Overall, the Carrera 4 packed almost the same technical specifications as the Carrera 2 model. The Targa top was quite a project to take off (compared to the simple and fast cabriolet process) so be prepared to garage it all the time or spend 20 minutes every time you want to enjoy open top fun.
Porsche added the rear wheel drive Carrera 2 variant to the range in 1990. It was developed alongside the 964 Carrera 4, Porsche waited a year to release the Carrera 2 as a 1990 model year car. Like the Carrera 4, the Carrera 2 was available as a coupé, Targa or Cabriolet. Think of the cabriolet as a C2 coupe but with a fabric roof and more fun and you are right on the money. It was popular amongst buyers, particularly in the United States, with a total of 11,013 units sold, making it the third most popular 964 model.

Porsche added the rear wheel drive Carrera 2 variant to the range in 1990. It was developed alongside the 964 Carrera 4, Porsche waited a year to release the Carrera 2 as a 1990 model year car. Like the Carrera 4, the Carrera 2 was available as a coupé, Targa or Cabriolet. Overall, the Carrera 2 packed almost the same technical specifications as the Carrera 4 model. The engine was the same 3.6 liter unit which produced 250 horsepower and a maximum speed of 162 mph. Looked like C4 but was 200 lb lighter and more fun to drive.
Porsche is the most successful marque in the 24 Hours of Le Mans and British drivers have played an important role in delivering these historical achievements, and in celebration of this success a special limited edition model – the 911 Carrera 4 GTS British Legends Edition was created. Designed by the drivers who took wins in the 24 Hours of Le Mans for the factory team – Richard Attwood (winner 1970), Derek Bell MBE (winner 1981, 1982, 1986, 1987) and Nick Tandy (winner 2015) – this model was developed by Porsche Cars GB and Porsche Exclusive Manufaktur.
A year after the Cayman S and the second generation of the Boxster were unveiled, Porsche released the non-S version of its mid-engine sport-coupe vehicle. The “regular” Cayman was still a sports car that could top a 0 to 100 kph (0-62 mph) in 6.1 seconds so it couldn't be called a “slow” car. It was slower than its brother S, but it was still a daily-driver sports-car. The Cayman was built to be not only a fast and nimble car but a practical vehicle as well.
While the first generation Boxster S was received with mixed feelings, the second generation was praised. With the introduction of the 718 Boxster, the car-maker showed a special commitment to the smallest member of the Porsche family and it arguably become the best sports car in the world. The Boxster S featured a 2.5-liter flat-four engine. It was turbocharged and with direct fuel injection and was good for 345 hp. Performance was up a lot, especially in the midrange, now that torque was 310 ft lbs. It helped rocket the Boxster S from zero to 60 mph in just 4.0 seconds and onto a top speed of 177mph.
Welcome to the four generation Boxster. The base Boxster was powered by a twin-turbo 2.0-liter direct-injection gasoline unit. It offered a total output of 300 hp and it was paired as standard with a 6-speed manual, while a 7-speed automatic (PDK – dual-clutch) was on the options list. In terms of design, it gets a more modern look and feel and the interior is upgraded. More tech, more power and more speed. The only downside is the loss of the aural pleasure of a flat 6 engine that is naturally aspirated and loves to rev to the sky.
