WOLFSBURG For 2007, Volkswagen has added 0.4 liter–little more than a twelve-ounce soda can–to the displacement of the base Touareg’s 3.2-liter V-6. The extra piston displacement bumps output to 276 hp and 266 lb-ft (increases of 36 hp and 37 lb-ft), while the addition of direct fuel injection helps return essentially identical fuel mileage. The V-6 Touareg is now about a second quicker to 60 mph, but it’s still no lightning bolt. Max power arrives later (6200 rpm versus 6000) and throttle response remains indifferent. But, in the end, who can argue with a little more pop?
