SL/R232: R231 SL63 vs R232 SL63




You keep conflating the issue of range with fuel economy — not sure why.
I also happen to own a few cars (fourteen); and since there are some that are not suitable for road trips due to their poor range, range is an issue to which I pay attention. If range doesn’t mean anything to you, well that’s just fine. But more people than you might think care about range. Simply put, whether you care about it or not, it doesn’t make much sense that a new generation car which grew in size and weight, was given all-wheel drive, and happens to have worse fuel economy — ends up having a smaller gas tank.
By the way: a little trivia.
Which brand of passenger cars has consistently produced cars with the largest fuel tanks of all cars?
Answer: Ferrari

After 1800 miles, my range on a full tank is 218 miles which works out to about 11.7 mpg. Around town I get about 8 mpg. Obviously I’m enjoying the car tremendously and doing the opposite of hypermiling. Years ago, I had a Range Rover Supercharged that had vanity plates that read “12-mpg”, so I don’t care about mileage or range either.



This is what RENNtech quoted for the R231 SL63
Rated by RENNtech: 605 HP @ 5,500rpm; 646 LB-FT @2,800-3,900rpm
So the HP and Torque in the R231 SL63 is definitely BELOW the new SL63 according to the dyno

Probably not; but you’ll be hanging out at the gas station much more often in an R232 SL.
Avid sports car enthusiasts (such as myself) often care about range — how often it’s necessary to go to the gas station — rather than fuel economy per se. If an excellent car has poor fuel economy, that’s okay with me as long as the gas tank is sufficiently sized. When a car is very powerful and has an extended range, that’s a very big bonus.
2. Avid sports car enthusiasts don’t consider SLs sports cars in the first place. I never did, and still don’t. But I’m really enjoying my ‘22 SL55.

If somebody says to me that so and so is rude, I will usually ask what is it that he or she says or does that you call rude. Actual behavior is understandable, measurable, and alterable, but the word “rude” can mean so many things to so many people that unless it is clarified, it is hard to deal with. Similarly, what a real sports car is can be difficult to understand often unless there is some measurable behavior or data. And certainly in one sense since the definitions we would find are all over the place then I guess it could be said whatever one considers a real sports car is one. It’s a little like art or beauty. Beauty is in the eye of the beholder, no?




In the old days
, there was Luxury Cars, Grand Tourers and Sports Cars. As a non Porsche example, there was no question MG’s, Triumph’s and e-type Jag’s were sports cars not a grand tourer or luxury car. Over the years things have become muddled. Probably because todays cars are so capable, but the terms “GT” and “Sports Car” have become freely interchangeable marketing buzz words contributing to the blurring of categories.
