External design of the two vans will show more Aerodynamics side glass, new tail lamp cluster, new chrome side trim, and a new front end of the latest corporate front grille and new lighting design to see the new Golf and Polo. Inside, the people mover Campervan Caravelle and California has added a new three-spoke steering wheel, new instrument, a gear indicator, and the latest audio equipment and navigation touch screen interface, a hard-drive storage, and USB connection. In terms of safety, the new generation Electronic Stabilization Program hill-start assist and emergency brake light function is added, the system Side Assist lane change and Tire Monitor Display.

Powertrain options including a new set of four diesel engines based on the Common-rail 2.0-liter inline-four, and available in 83, 101, 138, or 178 horsepower. Their latest changes, which provides diesel engines fewer greenhouse gases and enhanced features fuel economy of about 10 percent across the board. Available later in the year 2010 is Volkswagen’s seven-speed DSG automatic transmission mated with the 4Motion all-wheel-drive system on the new fourth generation Haldex coupling.

Although Volkswagen’s best selling diesel in the country lately, expect the US-spec or sports Caravelle California gasoline engine models in the next one oil stove, if offered. Price and full details of the new cars are expected closer to launch.

Volkswagen Touareg V6 TDI

The way Volkswagen talks up the $42,800 Touareg V6 TDI, you'd almost think it was the ninja of SUVs: a single package with so many highly developed capabilities that its gas-engined foes are annihilated and left on the side of the road with ninja 
shuriken lodged in their tailgates before they even realize they've been outdone. The engine alone promises reduced fuel consumption, fewer emissions, more power, more torque, better responsiveness and quiet progress. The only questions then are: Does it deliver and will anyone buy it? We took it for a spin to find out. Follow the jump for the story.

The diesel Touareg is essentially unchanged from the gas Touareg, so the sole story here is the engine. Volkswagen has done a Manhattan Project on its oil burner, going over everything that could make it more appealing to customers. It's a three-horse race in the non-gasoline powerplant derby, and diesels, hybrids and electric vehicles are fighting for share. VW and Audi have thrown their bets on the filly called Oil Burner, and the next couple of years will inform us whether it can win more than 5% of the market. 



To the engine, then. Sounding like something they got from the lab that created Wolverine, the compact engine block with a 90-degree V angle is made of high-strength vermicular graphite iron. Being 15% lighter than cast iron and not even 1.5 feet long, it has been fitted with aluminum alloy cylinder heads and weights 498.2 pounds. 

Within that block, the common-rail fuel injection system has been thoroughly refined. Electronically-controlled piezo fuel injectors permit injection pressures of 2,000 bar (29,000 psi) and spray through eight-holed nozzles for a finer fuel mist and better, more efficient combustion. Those injectors are also lighter and have fewer moving parts, and so can move at twice the speed of previous solenoid-valve injectors. With all of that, the number of injection processes per cycle can be varied and optimized as needed. 



The turbocharger, served by two intercoolers, has variable turbine geometry, with vane angles controlled by an electric servo motor. And get this: it's ribbed. The engine block has fluting to diminish vibration, and "all pathways on the engine mounts that could transmit vibrations to the interior have been eliminated." Finally, to aid engine packaging, the ancillaries and camshafts are driven by maintenance free chains mounted in back of the engine.

So, what's all that get you? A torquey little V6 that grinds out 221 hp and 407 lb-ft. That latter number comes as soon as 1,750 rpm, obviating the need for much footwork with the pedal on the right when it's time to git 'er done. 0-60 miles-per-hour is estimated at 8.5 seconds, which isn't all that bad for what is probably a 5,000-plus-pound vehicle (VW hasn't divulged its weight yet, but the Touareg V10 TDI rocked the scales at 5,800 pounds). 



It's not a sprinter, obviously, although neither is it a laggard. It is the marathon – or perhaps, the ultramarathon – where this car makes its name. VW says you'll get from Kokomo to the Poconos on one tank, which is 600+ miles for those of us who have nothing to do with either locale. Strictly by the numbers, you could go 660 miles if you used every drop of diesel in the truck: the Touareg is rated at 
25 miles-per-gallon on the highway, and has a 26.4-gallon tank.

In reality, you might be able to go even further. On a recent drive in the similarly-engined 
Audi Q7 on Audi's mileage marathon, we drove from San Francisco to Los Angeles, about 352 miles, and had a half tank left when we got home – and we weren't being kind with the footwork. 



In that Q7, we never got any worse than 21 mpg and we were doing some serious speeds through some serious mountains. The Audi Q7 diesel was billed as getting 33.1 mpg on the highway, so if you're a little kinder than we were to Mr. Throttle, we're sure he and his friend Mr. Gas Mileage will be a little kinder to you.

The engine has also been designed to be kinder to the environment, thanks to its use of VW's AdBlue system. Exhaust gasses pass through a catalyst where nitrous oxide is measured, and based on that measurement an appropriate amount of AdBlue treatment is injected into a dosing module. AdBlue is 32.5% urea, and mixed with the hot exhaust it breaks down into ammonia and converts the NOx to nitrogen and water. The resultant NOx levels are reduced by about 90%. 

The AdBlue tank is located under the spare tire, and is heated for cold weather climates since it freezes at 12 degrees Fahrenheit. The solution itself is non-toxic, odorless and biodegradable, and the tank holds enough for around 15,000 miles. When it needs to be refilled, that can be done during regular dealer service, and VW mentioned that places like JiffyLube will carry it. 



So here we have a 50-state diesel with an earth-friendly mien. But would you want to actually drive it in any state? In real-world driving, the V6 TDI shares a number of beneficial similarities with its 
V10-powered (former) sibling: it is quiet, powerful and refined.

At a cruise, the engine is as quiet as church just before a service, with only the slightest hum as any aural indication that the car is actually on. It is also steady as a rock: vibrations are essentially non-existent.

The V6 is 90 hp and 146 lb-ft down on the V10, but as we piloted the two-ton-plus SUV around snaking canyon roads, it was evident that VW has done its work to make sure all available power is applied to forward motion. Even on steep uphill grades, you don't worry about losing momentum because the Touareg will pick it right back up again on demand. The ride would be best described as business casual: crisp and smart, it suits all of the sporting situations you could wish to get into in an SUV. 



VW says "The 3.0 TDI produces a quiet, cultivated and harmonious sound. The hard 'knocking' and metallic rattling at partial load is history." That is true... when you're cruising. And that is what makes it all the more jarring when you get hard on the power. It's as if the sound insulation has evaporated with a flick of the accelerator. Engine noise commandeers the cabin. Under mild acceleration the noise is alright. Even under hard acceleration it isn't awful, it is simply unexpected because the contrast is so striking. We found the same thing in the V10 – get on the gas, and you can hear the horses neigh. 

That was the only demerit we gave to this vehicle. The only question is whether buyers will pony up the $3,000 premium for it over the VR6 FSI. The TDI will get you more power and much better gas mileage – 3 mpg more in the city, 5 mpg more on the highway, but these days, you'll pay substantially more for diesel at the pump, and that will likely more than neutralize the extra mileage. As fine a vehicle as it is, then, is it worth it? The best answer we can give to that one right now is probably this: We'll find out.

Volkswagen Finish 1-2 in Dakar

 The Volkswagen team made motorsport history in Argentina today (Sunday), claiming the first diesel-powered victory in the history of the world’s toughest motorsport event, the Dakar Rally. Not only that, but the team’s South African driver, Giniel de Villiers, led home a Volkswagen 1-2.

De Villiers, his German co-driver Dirk von Zitzewitz, and their TDI-engined Race Touareg crossed the Buenos Aires finish line – after more than 5000 km of competitive rallying – nearly nine minutes ahead of the sister Volkswagen of USA/South Africa pairing Mark Miller and Ralph Pitchford. Third place went to American Hummer pilot Robby Gordon, who was more than 100 minutes adrift.

De Villiers, 36, was ecstatic: ‘I am so happy to have clinched it for Volkswagen. This victory is worth more to me than any of the titles I won in touring car racing. The key to our success was the Race Touareg, which ran like a charm throughout, and I want to thank everyone at Volkswagen for that. I won the first Dakar Rally not staged in Africa, and it was the toughest event I have ever contested: definitely a genuine Dakar Rally.’

Kris Nissen, Volkswagen Motorsport Director, added: ‘We did it. We wanted to be the first manufacturer to win the Dakar Rally with diesel power, and we have achieved that, and with a one-two victory at that, beating our strongest rivals Mitsubishi and BMW.’ Carlos Sainz, who took six of Volkswagen’s 10 special stage victories before crashing out of the rally while leading, paid tribute: ‘Giniel and Dirk deserved to win this tough rally. One must never underestimate the Dakar Rally; you must prevail against it to win.’

There was jubilation in the team also that the Race Touareg of German pairing Dieter Depping and Timo Gottschalk made it to the finish; they placed sixth overall, well over eight hours behind, after several setbacks.

Volkswagen’s 2009 Dakar Rally achievement is the second time that the manufacturer has claimed a 1-2: in 1980, Swede Freddy Kotulinsky and Frenchman Patrick Zaniroli raced their Iltis machines to the top two overall. The Volkswagen win brings to a close seven years of domination by Mitsubishi.
