The behemoth Audi Q7 SUV has been replaced by a car that's smaller on the outside but, Audi claims, bigger on the inside. It's also way lighter. Jonathan Crouch takes a look.
Ten Second Review
The Audi Q7 used to be a bit of a whale, but the latest version loses the blubber, delivers some pin-sharp engines, yet somehow manages to offer more space inside. It's a car that now works smarter rather than harder and is right back into contention.
The launch of the original Audi Q7 back in 2006 was one of those moments that remains etched in the memory. When we first clapped eyes on the thing, it was like a friend showing you a spectacularly ungainly baby. "Well, he's certainly a bonny lad. What a bruiser," you felt like saying. Let's just say the Q7 wasn't about to win many beauty contests. We ran one for a while and grew to respect its build quality, practicality and ruggedness, but weren't so keen on the 4.2-litre V8's prodigious fuel thirst. In replacing the Q7, Audi have gone somewhere few manufacturers dare to go. They've made the car quite radically smaller. More than a foot has been lopped off the length of the Q7 and it's also a bit narrower and lower to boot. That seems a bit of a strange action in a sector where sheer presence counts for a great deal, but in doing so, Audi has also subjected the Q7 to the most radical weight loss plan we've seen in a production car.
Ever wondered why there was no S or RS version of the old Q7? Because it would have been like trying to turbocharge a continental plate. The thing was so big and lumbering that encouraging drivers to make it go faster would have been a recipe for disaster. The latest car doesn't go down that road either, but with all that weight excised from the chassis, it's a far nimbler thing. That tells in Audi's engine selection too. There's no hulking great V8 installed at launch. Instead we get a pair of far more efficient turbocharged 3.0-litre units. One drinks diesel, and the other petrol. The diesel's going to be the one getting the most play with UK buyers and it's a good 'un. With 270PS at its elbow and almost 600Nm of torque, it gives this lighter Q7 enough about it to be able to mix it with the class best. In fact, 6.3 seconds to 62mph wouldn't be bad for a hot hatch. Alternatively there's a supercharged 3.0-litre TFSI petrol unit which packs 330PS. This has seriously upped the ante over its predecessor. Where that car got to 62mph in 7.9 seconds, the sprint will now detain you for just 6.1 seconds. That'll be five point something to 60mph in old money. The Q7 rides on a steel springs as standard, although buyers can opt for air suspension. Another interesting option is a rear wheel steer function. At lower speeds, it counter steers the rear wheels for better manoeuvrability, while at higher speeds it steers them by up to five degrees in the same direction as the fronts to improve handling agility. All very Porsche 911 Turbo.
Design and Build
If you didn't have the two cars parked side by side, you'd probably never guess that the latest Q7 is so much smaller. The styling theme is evolutionary, although the car seems to sit lower on its springs, almost like a beefed up Audi super-estate than a typical SUV, an impression compounded by the aggressively raked windscreen. The chassis on which the Q7 sits will also form the basis for forthcoming Porsche Cayenne and Volkswagen Touareg variants, with proposed Lamborghini and Bentley SUVs also using a version. An increased reliance on aluminium has shed weight, with 100kg coming out of the suspension, 71kg out of the body and a massive 24kg from the doors alone. Despite being 370mm shorter, Audi has only reduced the wheelbase of this Q7 by 10mm, so the amount of room available for passengers is still vast. In fact, Audi claims an extra 21mm of kneeroom in the second row. Even the third row gets more space, with 24mm more headroom and an additional 20mm of shoulder width. This third row of seats are now dubbed 'Group 3 child seats,' and are electrically operated, popping up from the boot floor at the flick of a switch. With all seven seats occupied, you get 295-litres of boot space. In five-seat mode there's even more space than in the old model; fully 890-litres to the tonneau cover. The instrument binnacle features Audi's clever 1440 x 550 pixel Virtual Cockpit where you can configure the fascia display as a giant screen in a number of modes.
Market and Model
You'll want a decent specification from a luxury SUV requiring a £50,000 budget - and this Q7 doesn't disappoint. Included as standard is a fully revised two-zone air conditioning system. The operating concept uses fewer buttons and controls. Animated symbols in the display, the TFT display and the capacitive toggle switches allow intuitive operation of the air conditioning. There's a whole host of clever options available for the car, but we particularly liked the optional Audi tablets for the rear seats. One (or optionally two) Audi tablets with 10.1 inch screens serve as rear seat monitors. They're connected to the 'MMI navigation plus' system via WiFi, thus gaining access to the radio, media, navigation and car functions of the Audi Q7. Rear seat passengers can surf the Internet via the WiFi connection. Android-based, the system gives access to the huge number of applications, games, movies, music and eBooks in the Google Play Store. At the end of the trip, the Audi tablet can be removed from its mount and used offline or on any external WiFi network. It features a full HD camera, 32 GB of internal storage and an additional Bluetooth and NFC interface for connecting headphones, for example.
Cost of Ownership
Improving the aerodynamics, stripping all that weight out of the car and fitting even cleaner Euro6-compliant engines has had massive improvements in overall efficiency. To give an idea of how much better, consider this. The old Q7 3.0-litre TDI could get 38.2 miles from a gallon of diesel, whereas the latest version manages 49.6mpg. Emissions improve to 149g/km. Going for the 3.0-litre TFSI petrol engine sees fuel economy shift from 26.4mpg in its predecessor to 36.7mpg in this latest car. Think about that for a moment. The MK2 petrol model is almost as fuel-efficient as the outgoing diesel. The old TFSI unit emitted 249g/km, the new 179g/km. If this still isn't enough, you might want to wait for the 373PS Q7 e-tron quattro; a plug-in hybrid with a six-cylinder diesel and all-wheel drive. Audi claims 166mpg for this one, with a CO2 equivalent of less than 50 grams per kilometre. The lithium-ion batteries store 17.3 kWh of energy, enabling a range of up to 34.8 miles in pure electric mode.
Audi worked and worked on the old Q7, but all the polish in the world couldn't bring it up to the pace of the class best. Something radical was needed and something radical just happened. Significantly smaller, lighter and more agile but, thanks to smarter packaging, bigger in the passenger cell, the latest Q7 offers efficiency measures that are night and day compared to its Panzer-like predecessor. Even the shape subtly morphs into something more estate car-like. It'll be interesting to see whether the Q7's blend of talents can convince a market where many buyers choose according to predetermined brand loyalty. Can it bring customers back to a model that was never a front-runner? We wouldn't bet against it. The Audi Q7 has turned from a blunt implement to one of the sharpest vehicles in its sector. Who knows, it might even have pioneered a new niche on the sly. We can't help but have a sneaking admiration for what Audi has done here.
