Everything else is, and was, an SL rival. Whereas, the SL, well-- it's always just the SL. So perhaps the best way to understand the new SL is to trace its heritage. So when you're considering the origins of the Mercedes SL and this [INAUDIBLE] lightweight theme that runs through it, it's actually quite hard not to think about the origins of the word super-car. Because I'm sitting a car now-- W198-- from 1957 that has acclaimed top speed of a figure of 150 miles an hour and 225 horse power. To me, that sounds like pretty rampant performance for the day. I mean, what must this car have looked like to people in 1957? It still looks pretty futuristic now. They must have just thought it was the Millennium bloody Falcon. It's an amazing car. A really amazing car. And do you know what? Even though it created a dynasty of ruthless Mercedes Benzes, it is a much more specialized car than anything we have now with an SL badge on it. Not to say they aren't special cars now. They are. But they are much more rounded and much more usable. This is just wonderful. Here we are, roof down in Spain. I'm loving it. It doesn't have much grip. Steering wriggles around through this massive Baker-like rimmed steering wheel. The gear box is just lovely and precise. It just clicks into place. It's an absolute joy. Now, I have no idea what this car is worth, other than the fact that it's a big sum of money, but it's worth every penny. They dials are beautiful. The chrome, the metal, the leather. And that's before we even discuss the noise. Third gear. [CAR ENGINE ROARING] Like a DB5 having its bits fondled. It's just magnificent. But the whole car is completely glorious, and I'm in love. [CAR DRIVING] So what we have here is a W113 Mercedes 230 SL from 1968. To you and I, it's known as the Pagoda. Now, I've never driven one of these things before, so I'm actually pretty excited. I love Mercedes SLs. And I've always looked at this from a distance as a really, really elegant, beautiful piece of design. Sitting in it now, it's a high quality item. These really were premium pearls back in the day. They were furiously, fearsomely expensive cars. You can see why everything is either lovely words, painted metal, or chrome, or actually leather. So it's expensive. I'm wearing no seat-belt and I'm sitting upright, quite close to the screen. And it's impossible to avoid or resist the inclination to just hang an elbow off the door and cruise around. To me, it doesn't feel like a scratching sports car. Compared to a 1968 Porsche 911, this feels much more the cruiser. 2.3-D, just straight six engine, lovely throttle response. But you know what? This great big steering wheel actually gives you very little steering feel. So everyone that goes on about steering feel being lost by modern cars is, in fact, talking codswallop. I suppose this car also infused in me a sense of not wanting to go too fast. Yes, it's a performance car. But if I want to go quickly, this little 2.3 liter six cylinder engine is lovely. Listen to the noise. Here we go. I'll give you some noise. [CAR ENGINE ROARING] Delicious sounds and it's amazing how sharp the response is. But the SL is a car that doesn't want to be hurried. Doesn't want to be hustled. And this is quite a light car. 1,295 kilograms and with that 150 horse power, sweet little inline six. 2.3 liters, remember. It's honey. Very responsive. Mechanical fuel injection. It's a lovely little drivers package. Compared to an equivalent 911 of the era, this is much of a sports car but probably with a much broader appeal. It can scratch and go quite quickly if you want it to. But really it's about just sitting back and having a good time. And enjoying this gear change, which is a little Swiss watch in its operations. It's a short throw, and you feel the cogs meshing together. I love this car. It's really gorgeous. [CAR DRIVING] So in 1971, the cute little Pagoda W113 gave way to what Mercedes internally called the R107. Of course, to you and me it's the Bobby Ewing. I don't know about you, but to me this is the definitive Mercedes SL shape. This car was built for 18 years. That's the longest any Mercedes was ever built. They didn't stop making it until 1988. And the basic shape and styling stayed the same. Even today, it looks fresh. It's an absolute design classic. Now, the funny thing is I've already driven one of these before. And it was a 500SL automatic. That's the classic LA spec, isn't it? A great big bruiser of a car. You just stuck it in D. It went pretty fast. It was a bit wallowy. It wasn't a sports car in the conventional sense. But it was a lovely way of getting around. Today, rubbed my hands. They said, have go in an R 107 and presented me with a red manual 300SL. And I just thought, oh no, this is just rubbish. However, this is a bit of a revelation, this car. I'm loving it. 188 horse power from a three liter straight six. 1,510 kilograms without the hard top on it. It's not that quick. The gearing is a bit too long, but it makes this lovely straight six noise. It's a great place to be. You've got the heavily sprung seat and this enormous steering wheel. I mean, it really does steer with all the precision of a great, big yacht. But other than that, I think it's a lovely, lovely car. [CAR DRIVING] And so this is where all that knowledge and experience culminates, the new R231 Mercedes SL class. First impressions. Well, it's bigger, physically bigger, and longer. But it's lighter. The car now has a twin-turbo V8. This car has 435 horse power, 516 foot pounds of torque, and it weighs 1,785 kilograms. Do some maths, and you have a car that-- despite not being a dedicated AMG performance model-- has nearly the same power to weight ratio as a 2001 SL55. It's a really, really fast car. It absolutely shags it along. Now that's kind of a good thing but also a slightly awkward thing as well. First of all, you have a level of effortless performance that was just missing in the previous SL car. You stroke this thing along in drive, leave the gear box in its economy setting with the stop, start and gage and everything, and it's really, really fast. But it doesn't mean that the temptation is there to go really quite quickly.
