Evening, there are great power differences between the SL350 (245hp) and the SL500 (306hp) BJ 2004-2006? The 350, as I got with the 500er only with 2 cut-off cylinders. From the data sheet the vehicles separate nevertheless almost 2 sec. from 0-100 km/h. Because this hardly occurs actually irrelevant. Do both engines have the 5th gear transmission? Unfortunately I only know the 350er, because my father has an S350 L 4-M. With this car I find the engine in some speed ranges too sluggish. Thanks already in advance. Greetings Mondi
