GMC Sierra HD All Terrain X

Well why just have a V8 petrol when you could have a 6.6-litre, 910lb ft diesel?

---

Never let it be said that America can't do an imposing pick-up. Even by the standards of the genre, this GMC Sierra 2500HD All Terrain X (to give it its full name) is fantastically OTT. Huge size, huge power, huge presence.

It's in fact the third GMC in the All Terrain X series, suggesting ultimate off-road trucks are proving popular. This Sierra is notable for its sheer size - it looks massive even parked with other pick-ups - but also its new engine. Thought the 435hp of the Audi SQ7 was impressive? Think again. This GMC packs another, er, 10hp. But we all know torque is far more important where diesels are concerned, for dieselly stuff like towing and pulling and lugging trees around. Here the GMC trounces the Audi with 910lb ft of torque against 664lb ft. Unsurprisingly GMC says the 6.6-litre V8 diesel is the most powerful in its class. Transmission testing must have been fun with that.

Now, if you have a truck with twice the torque of an M4 GTS, you're going to want people to know about it. So the All Terrain X gets Goodyear Duratrac off-road tyres with 18-inch wheels, four-inch side steps, a bed-mounted bar (if you want to fit off-road lights, obviously) and one sod-off great exhaust. No mention of any official 'rolling coal' mods or vertical stacks but doubtless the aftermarket will be there if that's your bag. There are a lot of black body accents though, but best spec the other available colour (Summit White) if you want to see those. The standard Z71 off-road package should mean the looks can be matched with ability too.

The Sierra All Terrain X has been launched in Texas, which makes it hard to think of a more perfect vehicle to location launch arrangement. Prices have not been confirmed just yet, but it's probably one to add to the test-drive list for those after the ultimate do-it-all truck.

Big fan of American trucks, this is no exception!

[TurboHatchback]

Oh god yes, I would like one of those.

That would look awesome parked outside waitrose in sevenoaks

[irocfan]

looks like it could be fun

[willbowles]

If your Waitrose is anything like mine then you'll have parking wardens. They'll have a breakdown when you rock up in that and take up 4 spaces!

They're easy to tune as well. A friend of mine has his mildy tuned (exhaust, non-EGR, injectors, intake and remap) and it now has 700whp... utterly ridicilous. Drove it the other week, wheelspin in the dry at 80km/h, the thing weighs 3000kg and hits 100km/h in under 6 seconds... brilliant, and he rigestered it as a commercial truck so road tax, insurance etc. are all low

Nah, only one place in Sevenoaks to park it is here

That's the only man's oasis in a desert of ladies coffee shops and restaurants that keep re-opening under new management every week.

It's even got double width pavement so you can park this big truck up easily, whilst you buy your one shot toilet unblocker and some galvanised screws.

I am seriously looking at importing a Sierra from the States but I don't know much about the whole process. Is there anyone out there that can chime in with some wise words, on everything?

Those wheels are probably 7ft tall but they look tiny!

There are a few companies that can help but I've used ship my car on a few occasions & they've done a good job for me.

Or speak to Clive Sutton, also check out what states have lower taxes compared to where the truck will be shipped from.

[JCWbeast]

Love it. Need a black one to park next to my white Mini on the drive

[twiglove]

I'm running circa 500bhp and 987ft/lbs, can also confirm the tyres fit into one space at waitrose

there's a fair chunk of info on http://www.mocgb.net/ - look up Ron Fenton, lovely bloke and very helpful

The Duramax has the Allison transmission which is the best of the big three. They also have a really nice interior.

If I was to pick one id say I love the RAM simply because of the cummins unit, id consider buying one if they could creatively shoehorn one of those 5-6L diesels into something L200 sized, even if it had a bonnet like a viper

[K974]

buy a rhd one out of Australia!

The new ram 3500 cummins are rumoured to be coming out with 1000ft lbs of torque from the factory. The ram 2500 pulls very hard, definitely takes you by surprise.

In most states you pay sales tax at the point of registration - if you can avoid registering it you should be able to avoid sales tax.
