19 Best Roadsters of All Time

10. 1957 Mercedes-Benz 300SL Roadster

The 1957 Mercedes-Benz 300SL Roadster was first introduced to the public at the 1957 Geneva Motor Show. The popular roadster became known for the first-ever consumer fuel-injection, breaking the world record for fastest speed, and for being a commercial success in the United States. Featuring a top speed of 155 MPH, the 300SL also included a new rear suspension that included a single-point swing axle and an additional coil spring. The car’s engine is rated at 220 horsepower and is 2,996 cc in size and was sold with a four-speed manual transmission. The fuel injection system incorporated into the design of the car allowed it to produce almost 25% more power than the other Grand Prix racing cars of the time.
