Porsche 911 Turbo was launched 40 years ago and over the years the model has stayed true to the concept, evolving with the time, offering more and more power, along with the latest technology, safety and luxury features.

The first 911 Turbo generations were known for loosing control quite easily, but that has changed and today the 911 Turbo handles so well thanks to all the technology and all-wheel drive. Also the new standard 911 Turbo packs an impressive 513bhp and 486 lb-ft of torque.

One of the odd-balls of the 911 Turbo models is the 1989 911 Turbo flatnose convertible, packing 326bhp and 347 lb-ft of torque. Not bad for a car at that time. It is unmistakably Porsche, though the front-end is something you either like or don’t.

So how does it compare against the new 991 series Turbo Cabriolet and what has changed over the last 25 years. In the video below you can see the progress has been amazing and even though, Autocar calls it the “Battle of the Porsche 911 Turbo cabriolets”, it is more of a comparison.

The 1989 911 flatnose convertible is a very unique car and today there are just eight remaining in UK. Hit play to see the evolution of the 911 Turbo and how things have changed over the last 25 years.
