Automotive icons that have stood the test of time - from the Porsche 356 to the Mercedes SLExamine it! Mercedes SLIt's an automotive icon, with a history that dates back to the 1950s. Now, it's undergone some improvements. The Mercedes SL has a powerful engine, a nine-speed automatic transmission, five dynamic drive programs -- and the suspension is equipped with an Active Curve Tilting feature.The SL has always been a top-of-the-line touring roadster, and the new model continues that tradition. We're going to test an AMG SL 63 that has a power output of 430 kW. Test It! Subaru LevorgA muscular-looking front end and a striking air-scoop are not the sort of accessories you'd expect to find on a station wagon -- but they're a perfect fit with the Subaru Levorg.The name "Levorg" is a combination of the words "Legacy" -- the car it replaced -- plus "revolution" and "touring." The Levorg's design is based on the Subaru Impreza, but it's a cut above that model. The Levorg sells for just under €29,000 -- complete with four-wheel drive and automatic transmission. We take this new Subaru wagon out for a test-drive. Taste it! VW Passat GTEIn all-electric mode, the VW Passat GTE moves off almost without a sound. The 1.4 liter gasoline engine remains off and the vehicle is powered by the electric battery alone. In electric mode, the car has a range of 50 kilometers according to VW.The GTE takes around 2.5 hours to charge up fully if you use a public charging station, or over four hours if you plug in to a normal household socket. Apart from fully electric mode, the GTE also offers the Battery Charge Mode. Here the car is powered by the gasoline engine which charges the electric battery at the same time - useful for longer trips, especially on the freeway. That's the theory at least, Drive it! puts the GTE to the test to find out how it fares in practice.Test it! Opel CorsaIt's proved to be the ultimate bestseller: the Opel Corsa has been on sale for 34 years. In that time, four generations of the Corsa have come and gone, with over 12.4 million vehicles sold. The fifth generation is now on the market. We test out a 1.4 liter gasoline Corsa, boasting 74 kilowatts of power.The car is available both in a sporty 3-door version or the more practical 5-door model for everyday use. Both have an identical length of 4.02 meters. So our car tester wants to know if the cargo space is sufficient in the 5-door version, and decides to climb into the trunk himself. He's 1 meter 80 tall, but finds he's not disappointed. Vintage! Porsche 356 Super 90 ConvertibleIntroduced in 1948, the 356 was the first car to bear the Porsche name. Before then Ferdinand Porsche had developed vehicles for other brands at the design and engineering firm he'd founded in 1931. But the 356 was actually the brainchild of his son Ferry Porsche.The VW Beetle formed the basis for the 356, which underwent constant improvements during the 17 years it remained in production. We take a 1960 Super 90 convertible out for a spin. It features a 1.6-liter engine which generates 90 horsepower -- more than twice as much as the first 356 models.
