Audi RS7 vs Holden Spark

What's the difference?

The new-generation RS 7 Sportback heralds the further evolution of this large majestic beast, with more features, a beautifully finished cabin and with more grunt with the looks to match. You’d be hard-pressed to find a better combination of power, dynamics and comfort in the Audi range – apart from in the RS 6 Avant of course.

The marvels of local engineering strike again: the Spark LT definitely feels a cut above some of its budget competition from behind the wheel. It is well-equipped, too, and packed with connectivity and technology features. In short, it could be just the spark Australia's city-car segment needs.

The big news is the RS 7 Sportback now comes with five seats. The previous generation car had just two seats in the second row. I'll talk more on practicality below but for now let's examine the new styling.

This RS 7 Sportback has new broad, black mesh grille, flanked by gigantic side air intakes, narrow headlights, and a thin upper air inlet which is a hat tip to early racing Audis.

While that new angrier, more angular and menacing face is a showstopper, everything about the new RS 7 Sportback seems to be accentuated further.

Look at the wheels. The previous generation came with 21-inch rims, now the new normal for the RS 7 are 22-inches – they're huge. Those wheel guards also flare out 20mm more than a regular A7's and the rear haunches have bulked up massively.

Come to the back of the car and the diffuser and bumper have also been beefed up. Nobody sitting behind you in traffic is going to think this is just a regular A7.

Don't expect the RS 7 Sportback's insides to be just as hardcore as its exterior. The cabin is almost identical to a regular A7's. It's a stunning cockpit dominated by a dash which protrudes back towards the passengers and houses the media screen. Anther display for climate is set into the big centre console which divides the driver and co-pilot into almost cocooned cells.

The cabin isn't without its RS touches though – there's the sports seats with honeycomb stitching, fully digital instrument cluster with RS specific meters, the RS steering wheel, the Nappa leather on the dashboard and the doors, the aluminium inlays. The level of fit and finish is up there with the best that I've seen on any production car.

The RS 7 Avant is 5009mm long, 1424mm tall and 1950mm across for a wide planted stance.

There's only so much that can be done with a car in this bracket (there's hardly an abundance of surface metal to play with), but Holden's Korean design team have done an admirable job of inserting some excitement into what is traditionally a fairly bland category.

More youth appeal arrives courtesy of a huge array of personalisation options.

A powerful front end, with two fog lights sitting below the headlights, is dominated by a vaguely Kia-esque grille. And when viewed side on, the Spark looks to be sitting low, courtesy of standard 15-inch alloys that fill the wheel arches and tarmac-kissing side skirting that runs front to back. Two fairly heavy body creases also break up the metal monotony, running along the front and rear doors.

It's an energetic-looking package, and even more youth appeal arrives courtesy of a huge array of personalisation options, with Holden promising 33 different changes a buyer can make, including the wheel inserts, wing mirror caps and roof rails.

Inside, the focus is more on connectivity than luxury, so you can expect fake leather, hard plastics and fairly ordinary seat cushioning, but it's all nicely put together, and the basic feel is broken up by some well-placed style elements, like the coloured insert that runs the length of the dash.

The previous RS 7 Sportback was a four-seater, now it has five seats. That's right, a middle seat has been added to the second row, but, as you'd expect, it's not the best place be in the RS 7 Sportback, straddling the large driveshaft and ducking under the low roof-line.

That fastback profile does mean headroom in the second row is nowhere near as good as the RS 6 Avant's, but legroom is the same and, at 191cm tall, I can just fit behind my driving position with about 10mm to spare.

Up front it's not as spacious as you might think. That stepped dash protrudes into the passenger's space, the door pockets are thin and the centre console storage under the armrest is small.

Sportbacks are more practical sedans thanks the large opening offered by the hatch. The boot's 535-litre cargo capacity is great and only about 30 litres less than what you have in the RS 6 Avant.

For phones there's a wireless charger and two USB ports in the centre console storage box, while back seat passengers have two USB ports and a 12V outlets. There's also directional air vents and dual-zone climate control in the rear, too.

Nope. This is a pocket-sized car, namely because it has the same cargo capacity as your pocket.

Holden has stretched the space between the wheels to maximise passenger space, and as a result there's actually plenty of room in either row. But to add space somewhere, you need to take it from somewhere else, and that somewhere else is the boot, where you'll find a mere 185-litres of luggage space. The situation is improved by dropping the 60:40 split rear seats, but you'll be forever choosing between passengers and luggage.

Front seat passengers share a pair of cupholders, but rear seat passengers get none. They don't get room for bottles in their door pockets. Or door pockets at all, for that matter. The backseat does, however, get two ISOFIX attachment points, one in each window seat.

While the cheap and cheerful entry-level Spark, the $13,990 LS, plays smack-bang in the middle of the micro-car segment, the top-spec LT has bigger, and considerably more expensive, shoes to fill. At $18,990, the LT sails perilously close to its bigger and equally well-equipped competition.

For that money, the Spark needs to arrive wanting for little, and in most respects it does exactly that. For a start, a CVT automatic is standard, and is joined by some stand-out features in this segment, like cruise control, keyless entry with proximity unlocking, push-button start and a fake leather trim that Holden calls Sportec.

While navigation isn't standard, the Spark LT's seven-inch touchscreen is both Android Auto and Apple Car Play equipped, so phone maps fill the blank with ease.

The RS 7 may look like a large, well-mannered business class car, but think of it as a thug in a suit because this thing is a monster with a 441kW/800Nm twin-turbo petrol 4.0-litre V8.

That's almost 600 horsepower and the supercar acceleration that goes with it is brutal: we're talking 0-100km/h coming in 3.6 seconds. That also matches the RS 6 Avant and it's a tenth of a second faster than the Audi R8 V10 RWD supercar, (and also the previous-gen RS 7 Sportback Performance) and this is a large, four-door, five-seater.

Compared to the previous generation RS 7 Sportback Performance the power is down by 4kW, but torque is up by a whopping 100Nm. Give me torque over power any day.

Shifting gears is an eight-speed automatic transmission, sending the drive to all four wheels.

There's just the one engine available across the Spark range, and that's a 1.4-litre petrol unit that'll generate 73kW and 128Nm.

This is a large, all-wheel drive car with a 600 horsepower V8, but it also has a mild hybrid system in this new generation, which will switch the engine off at let the car coast down hills or at speeds under 22km/h.

Audi says this can save up to 0.8L/100km in real-life driving. That's great news, but consumption is still fairly high with Audi saying that after a combination of open and urban roads the RS 7 Sportback will have used 11.6L/100km.

Spring for the LT, and that's paired with a CVT automatic transmission, with Holden promising that combination will sip a claimed/combined 5.5L/100km (though we recorded a less impressive 8.0 litres on our test).

I've never met an RS model that hasn't been great to drive – these cars are way more than just tough body kits and big wheels. The engineering which separates the RS 7 Sportback from the A7 makes them more distant cousins than siblings.

As I mentioned before the RS 7 Sportback and RS 6 share more than the same twin-turbo V8, there are also the giant brakes in form of 420mm discs at the front with 10 piston calipers and 370mm discs at the rear.

The optional carbon ceramic brakes are the largest ever to be fitted to a production vehicle at 440mm at the front and 370mm at the rear, saving 34kg in mass over the steel brakes.

Now standard for the first time is Audi's Dynamic Package, which adds dynamic steering (a variable ratio) paired with all-wheel steering, a sport differential, and a 280km/h top speed.

Coming standard is adaptive air suspension and for $2850 you can option the Dynamic Ride Control suspension, which is a hydraulically activated adaptive damper system 

At the Australian launch, Audi supplied two RS 7 Sportbacks: one with the air suspension and the other with not only the Dynamic Ride Control system, but also the RS Dynamic Package Plus which adds the ceramic brakes and increases the top speed to 305km/h – this was the car I started off in.

I'm going to say right away that you don't need ceramic brakes for regular road use. Sure it means you can tell people that you have the biggest brakes in the world and they save you almost 35 kilos in weight, and, yes, they're resistant to fading, but they're expensive to replace and the steel ones are incredibly good.

I also feel the Dynamic Ride Control sports suspension isn't necessary in a car like the RS 7 Sportback. This is a Grand Tourer designed to eat up hundreds of miles at lightspeed in comfort.

So, while I found the first RS 7 Sportback with the big brakes and sports suspension sharper and firmer than the standard car, it didn't seem to fit with this vehicle's intent.

The regular RS 7 Sportback still accelerated with the same brutal force and roared at the scenery flashing past. It still handled through the tight corners superbly with excellent turn in, mind-boggling traction and grip, and excellent body control, but all in far more comfort.

This is the point – we covered hundreds of miles at the Australian launch of the RS 7 Sportback in a range of RS models, and sports suspension can go from great to gruelling on Aussie roads with their coarse-chip bitumen and potholes. The RS 7 Sportback, with its air suspension, not only made driving far more comfortable, but easier, too.

Holden's Aussie engineering team say they were able to get their hands all over the new Spark pre-launch, launching lap after lap of the company's proving ground as they tweaked the steering and suspension tune to better suit local conditions. And the results are very good.

The 1.4-litre engine doesn't generate a huge amount of power (though it is good for its class), but it's delivered in a way that makes the Spark feel like it's punching well above its weight, rarely feeling underpowered in everyday situations.

There is a certain skittishness to the way it drives at times.

The Aussie magic sprinkled over the suspension and steering transforms the way the Spark LT drives, both in the city and further afield. The ride nudges the firm side of the spectrum (but not enough to bother you over inner-city ruts and bumps) which translates to a low, flat feeling through corners.

All in all, the little Spark more than holds its own on more challenging roads. The steering, too, helps the Spark outshine the regular city commuters, with a naturally engaging set-up that always feels connected to the road below.

There is a certain skittishness to the way it drives at times, though, with the gearbox wanting to continue lurching forward for a split-second after you take your foot off the accelerator, which takes some getting used to.

Standard safety fare comes courtesy of six airbags, along with hill-hold assist, ABS and ESC, but it does miss out on more advanced technologies like autonomous brakes.

Springing for the LT will add rear parking sensors, a rear-view camera and cruise control as standard fare, though the lot can be added to the entry-level LS as part of Holden's Driver Assistance Pack.

The Spark range scored the maximum five-star ANCAP safety rating when tested early this year.

The RS 7 Sportback is covered by Audi's three-year, unlimited kilometre warranty which not only falls behind in duration compared to mainstream brands but also its direct rival Mercedes-Benz which now has five-year, unlimited kilometre coverage. 

Service intervals are every 12 months or 15,000km with a three-year plan costing $2380 and a five-year plan for $3910.

The Spark range is covered by a three-year, 100,000km warranty and requires servicing every 15,000kms. The Spark range falls under Holden's lifetime capped price servicing scheme, with trips to the dealership capped at $1,145 total for the first five services.
