Porsche is now celebrating 75 years since their first production model the 365 with a 357 Speedster concept car. It follows on from the 357 Concept shown off at the start of 2023 with one key difference, well two. Firstly this is a single seater, open-top car with a tonneau cover over the passenger side of the car. Secondly, the 4.0L Flat 6 engine has been replaced with two electric motors, one positioned on the front axle and the other on the rear.
