marstaff1tiguanOur Escape model is the off-road version of the Tiguan and therefore comes in at a smidgeon over £2000 more than the standard model. Both are equipped with VW’s 4MOTION intelligent four-wheel drive that kicks in when the system detects poor traction. I have always been a bit sceptical about these so-called ‘intelligent’ systems as they are reactive, i.e., you need your wheels to experience a bit of a problem before the electronics suss it out and then react accordingly and switch power delivery to a more even split between the axles.

I prefer a vehicle that lets me lock into four-wheel drive when I say so; which is why I will always be a bit wary of the intelligent SUVs that are swamping our 4×4 market these days. Yes, regular readers know that I am an old fashioned gal who loves a nice big transfer lever that you thrust into four low and know damn well that it is locked in and off you go into the wilderness.

Locking diffsLooking for better traction and more suspension control? Summit Racing has a variety of new products to offer just that, including the Yukon Gear and Zip Locker, which allows you to go from an open differential to fully lockable by flipping a switch. These lockers are built for both on and off-road use and work using air pressure to offer a variable locking action. If you are looking for this kind of diff control, check out the Summit Racing website, but beware – you’ll be bewitched by the enormous variety of performance products on show!

Varra tuning modulesAt the end of last year we heard about Varra, a British company with a new range of ‘plug in’ tuning modules. With offices in Australia, India and Russia, Varra has a website offering full details of suitable applications for the UK Market.  The company claims to have tuning modules available for around 3000 diesel vehicles, with a petrol version being launched later this spring. These modules work by altering the fuelling at certain rpm levels, thereby changing the power delivery; either for more power, or better economy. The Varra module can be manually adjusted, and fitted can be a DIY process, although fitting agents are available. Products have a two-year warranty. For more details about whether your vehicle is suitable, call 0845 838 1417 or you can email them on [email protected]

Five-month over-land tour We heard from retired businessman Les Carvell over a year ago now. He was proposing an overland trip and wondered if we would be interested in a feature. To be honest, emails like that are regular in the 4×4 Magazine office, often despite replying in a positive manner, we never hear another thing. In this case, Les Carvell was talking about a drive in Suzuki Jimnys around the ‘top of the world’ and we decided that it sounded very promising so we put in a word with Suzuki UK’s Head of Press and PR Alun Parry about it. Fast forward many months and it’s all about to happen! Les is joined with four other retired ‘avid Suzuki fans’ to begin a 28,000 fundraising tour around the world in aid of Save the Children and the Oakhaven Hospice in Lymington, Hampshire. The trip will start at Trafalgar Square on 31st March, and is planned to last for five months. All the participants are in their 70s, which is why they devised the whole project under the strapline: Heaven can wait, I’m busy!

Twisted new engine options for Defender Intriguing to hear that for 2013, the amazing bespoke modified Twisted model Land Rover Defenders will be available with thumping great General Motors V8 power, or a five-cylinder Ford turbo diesel unit, in place of the model’s usual 2.2-litre unit. While fitting the larger V8 unit seems a logical option, you wonder why Twisted didn’t consider the Range Rover option. As Twisted’s Charles Fawcett explains: “We’re continually asked whether petrol and diesel Range Rover V8s can be dropped into a Defender; while it is possible, it’s a matter of re-engineering the software to work standalone without all the modules and controls that the Range Rover has, but we don’t consider that to be the best solution. We’ve researched and experimented, and established that the GM V8 is a more suitable standalone fitment – and its character suits the Twisted Defender perfectly.”

Twisted was originally a Land Rover tuning specialist, but the business has evolved to produce highly distinctive and bespoke vehicles. Each model is unique and so the ability to offer a variety of engine options is an intrinsic part of why customers go to Twisted. The company plans to have the first new Ford turbodiesel demonstrator available later this month, with the 430bhp GM V8 ready to go in April – one customer V8 is already in the planning stage.

HYBRID SLOTS BETWEEN TIGUAN AND TOUAREGProving that perhaps you can keep slicing the cake smaller and smaller, and creating a niche of a niche, Volkswagen unveiled the new CrossBlue concept vehicle at this year’s North American Auto Show this January. This is a diesel-electric hybrid, which uses the company’s excellent TDI engine with two electric motors, DSG transmission to create an electric 4×4 system, which the boffins have dubbed ‘propshaft by wire’. Ignoring that for a moment, the six-seater vehicle is said to have a fuel consumption capacity of 134.5mpg.

The concept show vehicle had three rows of two seats, but it is expected that should this go into production, the second row would have a three seat option, making the vehicle a full seven seater. Obviously, and especially relevant for the US, the fuel economy figure was highlighted, but it is equally impressive to check out some of the other performance figures. For example, it is claimed that the hybrid engine has a power output of 305PS, and a significant torque figure of some 700Nm (516lb ft) thanks to those electric motors. This results in a top speed of some 127mph and a sprint from 0-60mph in a sprightly 7.0 seconds.

Hils BlogAfter all the excitement of this year’s Dakar Rally, isn’t it time that we had some more decent off-road racing on the TV?

Don’t know about you, but I have been glued to the British Eurosport TV coverage of this year’s Dakar Rally. It’s been especially interesting for us Brits and 4×4 lovers, as the Race2Recovery team of disabled British and US servicemen has been taking part.

You are, no doubt, well aware of this amazing challenge that the R2R team set itself and you may also be aware of the heartache and pain that has gone hand in hand with the team: the early retirement of team leader Capt Tony Harris’s Wildcat, the subsequent retirement of two others due to mechanical failure and a nasty roll that hit previous Dakar competitor Ben Gott (who was driving for the R2Rteam), and the horrific road traffic accident in which two Peruvians died and three R2R members were airlifted to hospital.

Pinzgauer 6x6If four-wheel drive is good, then does that mean six is better? We take a trip in a recently restored Steyr-Puch Pinzgauer 6×6 to find out. Now this is a real man’s off-roader!

I’m standing halfway down a very rocky hill, one I’ve had to winch up in the wet before now, and even competition trucks take a second look in the dry. The line, shown by recent tyre marks, zigzags out to one side, around the worst of the rocks that protrude high from the track. I’m waiting for Peter “Professor Pinz” Farrer to come along in his Steyr-Puch Pinzgauer, and I reckon as he curves the vehicle around those rocks I’ve got my shot.

Except he doesn’t. The Pinny comes straight down the track. Right over those rocks, under complete control, with just the barest of scrapes. I quickly reposition myself and shoot anyway. As the Pinny passes, I turn back to what it just drove over and take another look. Yep, it really did just drive over rocks that Jeeps and Nissans on 37inch tyres couldn’t handle. Takes a bit to impress me after all the years of off-roading, but I’m standing here in appreciation. And you know what? This is a completely standard vehicle.

ECU upgrades

The ECU (electronic control unit) on most engines controls the fuelling and ignition timing, which are essential for regulating the amount of performance produced. However, the settings for fuelling and ignition and timing often have potential for improvement, as they are intended to maximise fuel economy and keep emissions low. They also have to cater for a wider range of climates, so tweaking these settings can often result in better performance and better fuel economy.

There are a number of approaches to upgrading the engine’s ECU. One of the most straightforward is to fit a control unit between the ECU and the fuelling. This is known as a tuning box or tuning module. We assessed Tunit’s tuning module for diesel engines in the January 2013 issue (see pages 77-80), examining how to fit the equipment, how settings can be analysed and modified and whether this upgrade actually makes a difference. Such tuning modules provide a map (settings for fuelling) applicable to the engine that it is intended to be fitted to, which can be further fine-tuned using a dial on the side. Fitting is very straightforward in the case of common rail diesel engines, consisting of a plug connector that sits between the standard connection to the fuel injector rail. This helps to alter the signal to the fuel injection system without causing an error at the ECU.

March 2013 Issue of 4×4 Magazine

March CoverThere’s never a better time to own a 4×4 than when the entire country is blanketed in snow and ice – as it was a couple of weeks ago. I’m actually not a great fan – too cold for me – but it does certainly make me value my 4×4. A recent drive across East Anglia during the worst of the winter weather and my Hilux showed it was minus 9degC, yet I felt safe.

You’re not invincible in a 4×4, of course, and it’s stupid to think so, but driven properly you’re in a much better place. Not surprising then that used car website – motors.co.uk – was claiming that searches for 4x4s were up 24 per cent, with individual searches up even more for; Range Rover, Volvo XC90 and BMW X5s. Of course, if you’re looking for a second-hand 4×4 you should be checking our back issues for expert tips and advice! In the March issue, on shelves now, you’ll find a comprehensive buyers’ guide focusing on second-hand pick-ups……

Keep safe, and enjoy the issue.
