For American drivers in 2009 seeking a spacious and opulent SUV without the burden of guilt at the gas pump, the 2009 Audi Q7 3.0 Tdi emerged as a compelling solution. Audi reintroduced its full-size luxury sport utility vehicle to the US market, this time championing a clean diesel powertrain. Let’s explore if this iteration of the Audi Q7 successfully blends performance and luxury with environmental consciousness.
When the Audi Q7 first debuted in 2007, it offered robust gasoline engine options: a 280-horsepower 3.6-liter V6 and a potent 350-horsepower 4.2-liter V8. While these engines delivered ample power, the Q7’s considerable weight, tipping the scales at two and a half tons, resulted in less-than-ideal fuel economy. However, the 2009 Audi Q7 3.0 TDI offered a taste of the European experience, where diesel powertrains are favored for their blend of power and efficiency in large vehicles. This model adopted the same 3.0-liter common-rail direct-injected clean turbodiesel V6 found in the Volkswagen Touareg TDI, incorporating advanced emissions technology to meet stringent 50-state clean diesel standards.
At the heart of this clean diesel system is AdBlue aftertreatment. This technology injects a liquid urea solution into the exhaust stream, dramatically reducing particulate emissions by an impressive 98% compared to earlier TDI engines from 1989. But the 2009 Audi Q7 3.0 TDI isn’t just about being environmentally responsible; it also packs a punch. The engine delivers 225 horsepower and a substantial 406 pound-feet of torque, available just above idle. This torque figure notably surpasses Audi’s own range-topping 4.2-liter gasoline V8 by a significant 81 pound-feet, promising strong and effortless performance.
For those needing to haul, the 2009 Audi Q7 3.0 TDI boasts a hefty trailer capacity of 6,600 pounds when equipped with the optional tow package. A smooth-shifting six-speed Tiptronic automatic transmission comes standard, along with Audi’s renowned quattro all-wheel-drive system. The quattro system further enhances traction with front and rear electronic locking differentials and a center self-locking differential, ensuring confident handling in various conditions.
On the test track, the 2009 Audi Q7 3.0 TDI demonstrated its diesel muscle. Launching strongly, with the engine revving between 3,000 and 4,000 rpm, it achieved a 0-to-60 mph time of 8.6 seconds. This is only a mere 0.7 seconds slower than the gasoline-powered 4.2 V8 model, highlighting the diesel’s capable performance. The quarter-mile was dispatched in 16.6 seconds at just over 82 mph. While the power delivery of the 2009 Audi Q7 3.0 TDI might be characterized as more “on-off” compared to the progressive surge of some competitor’s turbodiesels, the readily available torque provides ample thrust for everyday driving and demanding situations.
Despite standard stability control, and without the optional adjustable suspension available on the 4.2 model, the 2009 Audi Q7 3.0 TDI, weighing in at a substantial 5512 pounds, exhibited noticeable body roll during handling tests through cones. Turn-in was initially responsive, but understeer and the vehicle’s inherent top-heaviness became apparent, influencing overall handling impressions. However, braking performance was commendable. The 2009 Audi Q7 3.0 TDI stopped from 60 to 0 mph in a respectable 129 feet, demonstrating impressive braking stability. The brake pedal, equipped with ABS and Brake Assist, felt firm and offered a nice, short travel.
Out on public roads, the 2009 Audi Q7 3.0 TDI delivered a comfortable and composed ride. The all-independent suspension, featuring a front double-wishbone and rear four-link setup, effectively absorbed road imperfections, providing a plush experience on a variety of surfaces. The Q7 is undeniably a large SUV, riding on a 118.2-inch wheelbase and stretching to an overall length of 200.2 inches.
Its imposing size is complemented by a striking design. The 2009 Audi Q7 3.0 TDI confidently wears Audi’s signature Nuvolari grille. The vehicle’s lines are clean and uncluttered, flowing smoothly from the lidded headlights across taut body sides and pronounced fenders to the wide, hatchet-shaped taillights.
Subtle “TDI” badges are typically the only visual cues indicating the diesel engine beneath the hood. However, the test vehicle featured door decals proudly proclaiming its diesel nature. It was also equipped with “S Line”-exclusive 20-inch wheels fitted with all-season tires, adding to its sporty appeal.
The “S Line” trim package further enhanced the already luxurious cabin of the 2009 Audi Q7 3.0 TDI. Brushed aluminum inlays accentuated the expansive leather surfaces, while shift paddles provided a touch of driver engagement. The top-tier “Prestige” trim level added even more premium features, including navigation, a rearview camera, a Bose surround sound system, and park assist. The test Q7 also included a sunroof. The leather seats are generously sized and comfortable, and the three rows of seating offer ample space, although the third row is best suited for children.
Accessing the cargo area reveals a power-operated tailgate (power open, manual close). With all seats in place, cargo space is a modest 10.9 cubic feet. However, folding down the seats expands the cargo area to a more practical 72.5 cubic feet.
Fuel economy is a key highlight of the 2009 Audi Q7 3.0 TDI. Government EPA ratings are 17 mpg city and 25 mpg highway on diesel fuel. In real-world testing, 20.1 mpg was achieved. While not exceptionally high, this figure represents a significant 25% improvement over the 4.2 gasoline V8 and is comparable to the Chevrolet Tahoe Hybrid, demonstrating the diesel’s efficiency advantage in a large SUV.
The 2009 Audi Q7 3.0 TDI started at a base price of $51,725. While a significant investment, it was only $4,000 more than the gasoline 3.6 V6 model and over $10,000 less than the fuel-thirsty 4.2 V8. The introduction of clean turbodiesel power effectively addresses the primary drawback of the original Q7 – its poor fuel economy. The 2009 Audi Q7 3.0 TDI remains a large, luxurious, and reasonably enjoyable SUV to drive. And while it’s not a fuel sipper, it now stands as a more economically sound option among large SUVs. The Q7 TDI represents a European approach to luxury and efficiency that American consumers seeking large SUVs would be wise to consider.
