PH Blog: at home with some range

Riggers falls for a diesel SLK, if only because he doesn't have to get off his backside to fill it up...



Last week I spent the majority of my driving time in a white Mercedes SLK. Powered by a four-cylinder turbodiesel. Now, if that sounds like a truly unholy (and most un-PH) combination of mildly girly boulevardier roadster mated to distinctly unglamorous powertrain, well, it is. But please bear with me.

We'll go into the whys and the wherefores of the diesel SLK in more detail another time, but here we'll just focus on one thing: range. Specifically, how nice it is to actually have some in a car with sporty pretensions.


It's perfectly commonplace these days to find a hairshirt eco-diesel that'll take you 600-700 miles between fill-ups, and fast diesel execs will give you 500 miles at a push, but it's deeply unnerving (in a good way) to find that something like the SLK can do similar numbers.

In a petrol-engined sports car of this sort, you'd often expect to get no more than 275-300 miles of touring range before the fuel gauge dropped sufficiently low for you to search out a fuel pump.

In the SLK 250 CDI I zero'd the trip having brimmed the tank, and the car's electronic brain was still giving me a remaining range of 130miles after 465 miles of driving.

The key to the appeal of this is that it's just so liberating, the opposite of the so-called range anxiety you get with electric cars. Let's call it range confidence - the ability to start pretty much any journey and know you can finish it in one fell swoop.


The SLK diesel seems to relish hard work, too. Part of my week's driving was a trip from Nottingham to Woking that I made using a mix of A-roads B-roads and motorway (I couldn't face the 50mph section of the M1). And the SLK refused to increase its appetite for fuel, the trip computer suggesting fuel consumption in the 40s mpg even during prolonged periods of 'making progress'. I guess you can thank a relatively low kerb weight and a massive wedge of mid-range torque for that.

The diesel SLK is far from perfect, mind - the diesel rattle is genuinely intrusive and rather grates in a car that ought to be about cultured cruising - but it definitely has its appeal, not least in that brilliantly liberating range.

Though perhaps the diesel sports car formula is a little more slickly expressed in the form of the BMW 640d, albeit at almost twice the price...

Makes a lot of sense... all the looks of a sports car, with a big splattering of diesel economy.

Given how few people buy the SLK/Z4/TT to actually drive them hard, you can see why Merc are slotting the oil burner in.

You are lost to us Riggers ..... wink

Let me show you another car capable of 500-600 mile range on a tank. driving

Now what are you going to choose?

2 problems with the Merc.

1. It's a diesel
2. It's a Mercedes
2a. You can buy a proper car for that sort of money.....

An utterly irrefutable argument, Jeremy biggrin

In fairness, I don't particularly like the Merc, I just like the idea of being able to travel a decent distance on a single tank! smile

It has it's merits...

In my old R53 Cooper S that was tweaked up to around 225bhp, my average range on a 10 gallon tank was around 240 miles. This meant for instance if I went to Blackpool, I would just about make it there on the tankful. When I got there, the red light would be on, and quite often I had to splash some more in at Stafford, especially when heavy traffic was a concern.

Now, if I take the diesel Fiesta with its 8 gallon tank, getting there is not a problem, and if I'm sensible, it will get home on the same tank! It's just a nice feeling to be able to drive somewhere (especially if you've not been there before), and not have to worry about hunting for a fuel station.

Yes, it's only a bloody Fiesta, but it balances out the V8s.

It still looks like the previous generation SLK with an 80's grille dumped onto the front!

In a fortnight I'll set sail for the IoM ferry at Heysham, and hope to get there from Sussex just on one tank - in my MR2. Last fill up - better than 41 mpg, 330 miles, current purchase price probably sub £4k.

One day I'll trade up to a diesel exec-barge, but for now I'll make do with C20 technology.

A very worthy pursuit I fully approve of. But you don't need a poncy diesel Merc to travel a decent distance on a single tank wink

Thought this was going to be about a Range Rover with a big thumping V8, find it's about an SLK with a very WRONG engine frown

Riggers, I thought you were older than 19. Would you also put the provate plate on this? wink

Sorry, I couldn't resist. hehe

The hideously ugly R172 made even worse with a rattly diseasel engine.

I can't think of much worse. Even a Trabant had character!

Fer Gawds sake fill up before you get on the ferry. Petrol ain't cheap on the Island. Especially around TT time. Usually goes up a few p in practice week....

...but only with the long range fuel tank I think...my best is about 450 miles on the standard tank

Sorry, but if the diesel rattle is that bad I couldn't accept it. Part of an open top sports car, actually any open top car, is being able to enjoy the sound of the engine, a rattle just won't cut it.

I accept the argument for a longer range though, I'd love not to have to fill up quite so often. At my current average mpg of ~20mpg I'd need a very, very big tank to get 500 miles and really wouldn't fancy dropping £150+ every time I filled up.

I love the idea of a mega-range GT. My in-laws have a house that is about a 650 mile drive from home. Whilst the journey is easily undertaken in a day, I have to stop for fuel at least once, and sometimes twice. Would love something that could do it non-stop cruising at 130kph.

An Alpina D3 will come pretty close to this range/speed combo. Plus the handling & grip is phenomenal.
