Review and road test of the Audi A4
Audi's A4 has sharpened up its act a little in the face of tough competition from BMW's 3 Series, Mercedes' C-Class and the Jaguar XE in the image-conscious compact executive sector. Jonathan Crouch takes a look.
Ten Second Review of the Audi A4
This fifth generation Audi A4 now features a sharper look and continues to claim to be class-leading in nearly all the areas that really matter to business buyers in the compact executive segment. That means efficiency, cabin quality, practicality and technology. As a result, it'll be hard to ignore if you're looking for a car of this kind.
Audi knows a thing or two about mid-sized family cars with a prestigious feel, compact executive contenders like this A4. This model, along with BMW's 3 Series, has driven huge growth in that compact executive segment, vanquishing Mercedes' C-Class in the process. Today though, things are different. The C-Class has been rejuvenated into a much stronger proposition, the 3 Series range has been usefully improved and a very accomplished class rival has arrived in the form of Jaguar's XE. This MK5 model A4 is Audi's response.
What we have here is a car that's lighter, sleeker and cleverer than it's ever been. As a result, this Audi is inevitably more efficient too, with a tax-beating sub-115g/km of CO2 WLTP-rated figure now promised on the most frugal diesel models. Inside, we're promised the classiest cabin in the segment - and one of the most technologically advanced. Plus, as usual, there's the option of quattro 4WD and either saloon or Avant estate bodystyles.
The A4 has always struck an appealing balance between handling and comfort and with this MK5 model, the Ingolstadt engineers sought to improve its credentials still further by developing a new five-link suspension system. Optional adjustable shock absorbers with 'sports' and 'comfort' modes will enable owners to get the most from this and a dynamic steering system is another extra cost feature that'll reward those you like their driving. Both features can be controlled through the standard Audi drive select driving-dynamics system, which alters throttle response and auto gearshift timings in its most basic form. Talking of auto gearshifts, the old CVT automatic gearbox has gone, replaced by a seven speed dual clutch 'S tronic' unit that claims to be able to improve both performance and fuel consumption.
As before, the A4 differs from its BMW 3 Series rival in its use of front wheel drive for most models. Also as before though, quattro 4WD is optional - and standard on the top V6 variants. The most powerful of these models even has the option of a sports differential for the rear axle to maximise traction. Refreshingly in a segment dominated by cars fueling themselves from the black pump, TFSI petrol models are still very much part of the mainstream A4 range, a 150PS 1.4-litre '35 TFSI' unit offered alongside a pokey '40 TFSI' 2.0-litre powerplant offering either 190PS or 245PS. There's also a 354PS 3.0-litre TFSI sporting S4 model near the top of the range. And a 450PS 2.9-litre V6 RS 4 Avant model beyond that. Most A4 buyers though, will continue to want a diesel, probably the 2.0 TDI 150PS '35 TDI' variant, which gets to 62mph from rest in a brisk 8.6s. If you want more diesel power, then a 190PS '40 TDI' version of this unit is also available, plus there's a 286PS 3.0 TDI V6 '50 TDI' model further up the range.
Design and Build
The external changes made to this fifth generation A4 are relatively slight. The volume 'SE' and 'Sport' versions get a revised front and rear bumper design, more pronounced side skirts, a special finish for the Singleframe and side air inlet grilles, a roof edge spoiler in Avant versions and a rear diffuser flanked by new look trapezoidal tailpipes. The 'SE' versions retain wheels of the same 17-inch diameter as before but in a new design, while 'Sport' models upgrade to a smarter, larger 18-inch wheel. The top 'S line' and 'Black Edition' models get a more striking 3D-look finish for the Singleframe front grille, plus 'S line' variants get new 19-inch wheels and a re-designed rear diffuser.
Otherwise, it's as you were, which - to remind you - sees this MK5 model A4 riding on a light, stiff MLB platform and boasting the lowest drag coefficient in its class. As ever, there's a choice of either saloon or Avant estate bodystyles, the latter offering 505-litre boot - or 1,510-litres with the rear seats folded.
The interior is of course typically Audi and a very classy place to be. Everything is well laid out with high grade materials in all areas you'll interact with regularly. There's the option of getting an 8.3" touchscreen mounted on top of the dashboard but even if you stick with the standard centre dash infotainment screen, you'll get an up-to-the-minute set-up able to support the latest Apple CarPlay and Android Auto connectivity.
Overall, you wouldn't call the appearance of this A4's cabin exciting but it would certainly be a soothing environment for long journeys. It's surely clever, a key option being the neat 'Audi virtual cockpit' we first saw on the TT sportscar. This replaces all the dials in front of the driver with a 12.3-inch high resolution LCD screen.
Market and Model
Prices have inevitably risen slightly, but still occupy much the same bracket as before, so expect to be paying somewhere between £29,000 and £40,000 for most models, with a premium of £1,400 for the Avant estate bodystyle. You get four trim levels - 'SE', 'Sport', 'S line' and 'Black Edition'. And there's a choice of three transmission options, a six-speed manual gearbox, plus two auto set-ups, a seven-speed dual-clutch S tronic and an older-tech eight-speed tiptronic.
At least standard equipment is pretty complete across the line-up. All trim levels include alloy wheels of at least 17-inches in size, Xenon headlights with LED daytime running lights, the 'Audi smartphone' interface, the 'Audi drive select' driving dynamics system, three-zone climate control and a 7-inch colour MMI infotainment monitor. We'd want to look at a couple of key options. The 'Audi phone box' connects smartphones to the on-board antenna and charges them. Meanwhile, for discerning hi-fi fans, a Bang & Olufsen 3D Sound System with innovative 3D sound is available.
As for safety, well along with the usual airbags and electronic safety nets such as ABS and stability control, there's optional active lane assist, a rear cross traffic alert, collision avoidance assist plus a cruise control system that assists with tiresome traffic-jams.
Cost of Ownership
Running costs are of course a vital consideration in this segment and this A4 offers some impressive WLTP-rated numbers thanks to this generation model's weight reductions and that sleeker shape. The volume 2.0 TDI 150PS '35 TDI' diesel variant delivers best-in-class readings of up to 65.7mpg on the combined cycle and CO2 emissions of 114g/km. Opt for the pokier 2.0 TDI 190PS '40 TDI' variant and the figures become up to 62.8mpg and 118g/km, so there's no huge penalty for the extra performance. The 1.4-litre 150PS '35 TFSI' petrol engine manages up to 48.7mpg on the combined cycle and up to 133g/km of CO2. Also deserving of a special mention is the 2.0-litre '40 TFSI' petrol engine with 190PS. It manages up to 47.9mpg and slashes CO2 output to as little as 136g/km through the use of a smart combustion process developed using the familiar Miller cycle as its basis, and will be notable for its ability to deliver optimal response across the entire engine speed range.
All A4s come with a three year 60,000 mile warranty which can be extended to four years/75,000 miles or five years/90,000 miles for a fee. Audi residuals are some of the best in the business, assuming you pick a desirable engine and trim combination. Some restraint on the all too tempting options list will help too.
Audi has spent nearly a quarter of a century perfecting its A4 - and that really shows in this fifth generation model. It's a spacious, classy car that's very composed to drive and is fully conversant with the kind of hi-tech design and faultless cabin quality that its target junior executive market likes to expect. So it stacks up in the showroom just as well as it does on the balance sheet, with running cost returns that with most engines will make it your company accountant's go-to choice.
Even more than before, this A4 feels like a car that's been lovingly and very carefully considered. The depth of engineering and the thought that's gone into the tiniest details combine to further enhance the warm fuzzy feeling that's charmed Audi customers for years. If you're one of those people, then you'll like this car very much. And even if you're not, you'll find it hard not to be impressed by way it systematically ticks almost every box on the compact executive market wish list. It's very thorough. And very Audi.
