The S500 is the first of the petrol engines on offer in the new S-Class and for those put off by diesel or seeking the smoothness of a V8 then it's a great choice. Based on a 4.7 litre V8 it produces a creamy smooth delivery of 455 horsepower, enough to send the saloon to 60 mph in just under 4.6 seconds and on to a top speed that is limited to 155 mph for safety. A V8 just feels right in a luxury car like the S-Class and the S500 has been the biggest seller in markets like the US for a long time, and is now gaining popularity in the UK thanks to diesels recent negative publicity and petrol engine resale values do seem to be significantly stronger than diesel at the moment. Fuel economy is down on the 350d as you would expect so the diesel makes sense for those doing 20,000 miles a year or more still, but for those doing lower mileages then the petrol is the way to go.
