Audi RS Q3 vs Audi Q7

What's the difference?

The Audi RS Q3 Sportback edition 10 years is dynamically brilliant, beautifully finished and surprisingly civilised on day-to-day duty. A polished compact performance package that even in this special 'get-it-while-you-can' guise offers compelling value relative to its direct competitors.

The Q7 was at risk of irrelevancy due to the unfortunate timing of its rivals' life cycles, but Audi made sure that wasn't going to be the case.

As far as mid-life facelifts go, Audi has knocked it out of the park with the Q7, so much so that the case can be made it's now the class leader.

In many ways this Q7 feels like an all-new model, which is quite something. More importantly, the positives well and truly outweigh the negatives.

There's a lot going on with the RS Q3's exterior design; a mix of jagged lights, hard character lines, broad haunches and multiple vents surrounding the brand's signature, six-sided grille up front.

The big 21-inch rims fill the arches nicely and the rear features a deep diffuser with fat exhaust finishers poking out either side.

It's a purposeful, macho look and the Sportback edition 10 years is defined by a black package which adds gloss black to the side window trim, front spoiler blade, side blades, rear diffuser and exterior mirrors.

The limited edition is available in two colours, 'Chronos Grey metallic', which is unique to this model and 'Dew Silver matte' which will now be added to the broader RS Q3 colour palette.

Premium performance feels like the dominant theme inside with a typically Audi tech-focused approach including high-quality brushed metal elements, matt carbon inserts and quilted leather trim on the heavily bolstered front seats.

A meticulous attention to detail is obvious and the bottom line is it's all about the driver. A grippy, flat-bottom, leather-trimmed steering wheel looks as good as it feels, sleek screens enhance the racy vibe and the mix of physical and digital controls is sensible.

Good on Audi for throwing the kitchen sink at the second-generation Q7. As far as mid-life facelifts go, this is a really good one.

Up front, the headlights, 'Singleframe' grille and bumper have all been redesigned to ensure the Q7 isn't out of place in Audi's new-generation line-up. Either way, this is a large SUV with presence in spades.

Changes around the side are less drastic, limited to new sills and fresh sets of alloy wheels, including the 20-inch items seen here, which we reckon are pretty unexciting.

The rear end is the best angle thanks to the redesigned tail-lights and rear diffuser, both of which look great. We particularly like the former's segmented design, shared with the headlights.

That said, the real story is happening inside, where Audi has well and truly flipped the script. The old cabin was ageing well in some regards, but not others, and that was reason enough for a complete overhaul.

If the new interior design looks familiar, it's because it is, having been lifted from the much newer – and mechanically related – Q8 large SUV.

Needless to say, it's a technological tour de force, with not one, not two, but three large display screens dominating the cockpit.

Of course, Audi's much-loved version of a 12.3-inch digital instrument cluster is one of them, although it's running new software now.

What is completely new, however, is the pair of stacked central touchscreens, with the top unit measuring 10.1 inches in diameter and the lower item checking in at 8.6 inches apiece.

Both are powered by Audi's latest-generation multimedia system, with the former handling most functions, while the latter is responsible for the climate controls.

Aside from being a fingerprint magnet, this set-up works pretty damn well. Yes, some functions require a few too many taps to get to, but the acoustic and haptic feedback bring some unexpected tactility to what is a largely buttonless system.

Look past the obvious, though, as it's more or less business as usual for the Q7, which is chock full of lovely materials, including the 'Cricket' leather upholstery seen here.

Take for instance the soft-touch plastics used on the upper dashboard and door shoulders. Even the hard plastics found lower down look and feel suspiciously good!

Metallic trims are used throughout to brighten up the interior, while gloss-black finishes are liberally applied to the dashboard and centre console. Frankly, we could do without them as they are fingerprint magnets. Yep, keep a microfibre cloth in the glove box.

Snug but spacious enough, the RS Q3 Sportback's driver and front passenger are provided with plenty of breathing room without upsetting the intimate, performance car feel. Just be prepared for a bit of head-ducking physical origami when folding yourself into either of the heavily bolstered front seats.

Storage includes door bins with room for bottles, two generous cupholders in the centre console, a lidded tray in front of the gearshift (which doubles as the wireless device charging bay), a storage compartment and owners manual holder under the front seats, a modest glove box and an adjustable front centre armrest with storage compartment.

Given this car measures just over 4.5m end-to-end, a close to 2.7m wheelbase is significant  and rear room is generous given the Q3's overall footprint. Plenty of head and legroom (for me at 183cm) with enough width for three adults on short journeys. A trio of up to teenage kids will be fine.

The back seat is able to slide for extra legroom (and slightly less boot space), while backrest angle is also adjustable.

Storage runs to small bins in the doors, a fold-down centre armrest (with two pop-up cupholders) and storage nets on the back of the front seats. Directional and temperature control in the rear for the ventilation system is a big plus.

Power and connectivity options run to a 12V outlet and two USB sockets in the front (Type A and C), another two Type C sockets in the back and a second 12-volt jack in the boot.

Speaking of which, cargo volume with all seats up is a handy 530 litres, enough to swallow CarsGuide's three-piece luggage set or large pram (the latter with room to spare) and 1400 litres with the 40/20/40 split-folding rear seat lowered.

The loading lip is low, a stainless steel sill protector helps minimise scuffs and scratches and the hands-free power tailgate is welcome.

If you're keen to hook up the boat or horse float the RS Q3 is able to tow a braked trailer up to 1900kg (750kg unbraked), but don't bother looking for a spare of any description, a repair/inflator kit is your only option. Boo...

Measuring 5063mm long, 1970mm wide and 1741mm tall in facelifted form, the Q7 is large for a large SUV, which goes some way to explaining why it's only available with seven seats.

That said, the third row is more of temporary solution than a permanent one, even for kids.

Granted I'm an adult that's 184cm tall, and therefore not the target audience here, it's still tight back there, albeit up with the best in class.

With the second slid all the way forward, I manage to have my knees pressed up against the seat backrest, while headroom is severely limited.

Footwell space is okay, and so too is toe-room. Again, children will cope, but only on shorter journeys.

Ingress and egress to the third row is made easier by the 40/20/40 split-fold middle bench, which can tumble forward easily with the pull of a tab and then a latch. It's not glamorous, but it's doable.

Conversely, the second row is spacious and easy to get in and out of, even when set up to make the rear occupants as comfortable as possible.

Behind our driving position, around 10cm of legroom is available, depending on the positioning of the bench. No matter what, though, there's plenty of toe-room, and two inches of headroom is on offer, despite the panoramic sunroof.

Indeed, this is one of very few SUVs that can accommodate three adults abreast in relative comfort, even with the transmission tunnel reducing footwell space.

For reference, top-tether and ISOFIX child-seat anchorage points are spread across the second and third rows.

Cargo capacity with the power-folding third row stowed is generous, at 865L, and can be expanded up to 2050L with the middle bench stowed. An undisclosed amount of space is available with all seven seats in use. Either way, it's more than enough for the weekly shop (as you can see in our pics).

The boot is made more useful thanks to the inclusion of four tie-down points and one side storage net, while the lack of a load lip makes dealing with bulkier items a lot easier.

The only real issue we had was where to store the load cover when not in use. There's no false floor to gobble it up, meaning it'll annoyingly live at home when you've got six or more people on board.

That's not to say the Q7 doesn't have other storage options; it's got plenty of them, such as the useful storage nets on the back of the front seat backrests.

The glove box is pleasingly large, although the central storage bin is not, with most of its space taken up by the wireless smartphone charger.

The door bins are simply massive, with the front items capable of accommodating a large bottle and two regular ones, while their rear siblings can take one of each.

Two cupholders are located between the driver and front passenger, while another pair is hidden in the middle row's fold-down armrest. Rear occupants are treated to two smaller items.

Connectivity-wise, in an old-school twist, four USB-A ports are split between the first and second rows. In both instances, a 12-volt power outlet is found nearby.

The former's input options are located in the central storage bin alongside SD and SIM card readers, while the latter's reside at the rear of the centre console, below the central air vents and climate controls.

The entry-level 45 TDI variant kicks off the new Q7 line-up from $101,900, plus on-road costs – $4100 higher than its direct predecessor, although Audi claims more than $15,000 of value has been added.

Meanwhile, the mid-range 50 TDI version tested here costs $6000 more than before, at $112,900, in exchange for more than $20,000 of added value. It can also be had in S line guise for an $11,000 premium.

Standard equipment not already mentioned in the 50 TDI includes matrix LED headlights, dusk-sensing lights, rain-sensing wipers, 285/45 tyres, a tyre repair kit, auto-folding side mirrors (with heating and auto-dimming), and a hands-free power-operated tailgate.

Inside there's, satellite navigation (with live traffic updates), Android Auto and wireless Apple CarPlay support, digital radio, a windshield-projected head-up display, keyless entry and start, power-adjustable front seats with heating, four-zone climate control, a power-adjustable steering column, an auto-dimming rearview mirror and ambient lighting.

Not only are the rivalling BMW X5 xDrive30d ($117,900) and Mercedes-Benz GLE400d ($124,400) more expensive, but neither matches the Q7 50 TDI on value-for-money.

The RS Q3 Sportback is powered by a 2.5-litre in-line five-cylinder intercooled turbo-petrol engine sending drive to all four wheels via a seven-speed dual-clutch automatic transmission and Audi's quattro permanent all-wheel drive system based on an electronically-controlled multi-plate clutch pack.

Featuring a cast iron block, alloy head, direct-injection as well as variable intake and exhaust cam adjustment, the (EA855) engine features a special firing order (1-2-4-5-3), the odd number of cylinders producing a signature engine sound and exhaust note reminiscent of the 1980s 'Ur' Quattro.

Peak power is 294kW from 5850-7000rpm and maximum torque is 480Nm delivered across a broad plateau from 1950-5850rpm.

The 50 TDI is motivated by a 3.0-litre turbo-diesel V6 engine, producing 210kW of power from 3500-4000rpm and 600Nm of torque from 2250-3250rpm.

For reference, the 45 TDI has the same unit but develops 170kW from 3250-4750rpm and 500Nm from 1750-3250rpm.

The former sprints from a standstill to 100km/h in 7.3 seconds, while the latter is 0.8s quicker, putting it in hot-hatch territory.

Either way, an eight-speed torque-converter automatic transmission sends drive to all four wheels via Audi's signature quattro system.

Both variants also feature a 48-volt mild-hybrid system, which consists of a belt alternator starter (BAS) connected to the crankshaft, and a 10Ah lithium-ion battery pack located under the boot floor.

And for those looking to do a little more than usual with the Q7, maximum braked towing capacity is 3500kg.

Audi's official fuel economy number for the RS Q3 on the combined cycle is 8.9L/100km, the 2.5-litre turbo-petrol five-cylinder engine emitting 204g/km of CO2 in the process. Stop-start is standard.

We covered city, suburban and some freeway running on test, returning an (indicated) average of 9.6L/100km. And that's pretty good, given we pushed on enthusiastically on a reasonably regular basis.

The fuel tank requires 63 litres of 98 RON premium unleaded to fill it which translates to a theoretical range of just over 700km, shrinking to around 650km based on our real-world number.

The 50 TDI's claimed fuel consumption on the combined cycle test (ADR 81/02) is 6.8 litres per 100 kilometres, while carbon dioxide emissions are 180 grams per kilometre.

Audi says the aforementioned 48V mild-hybrid system reduces fuel consumption by 0.7L/100km thanks to its coasting ability, which sees the engine turn off for up to 40 seconds between 55km/h and 160km/h. It also engages idle-stop from 22km/h. In reality, it all works pretty well.

During our week of testing, we averaged 8.9L/100km with limited highway driving, which is a pretty solid result. Naturally, longer journeys will see that figure come closer to the claim, if not exceed it.

It's also worth noting the standard fuel tank takes 75L of diesel, although the optional item accommodates 85L. The 50 TDI also requires AdBlue, with a 24L tank on board.

For reference, the 45 TFSI manages 7.0L/100km and 184g/km.

It still seems counterintuitive when a high-riding SUV is tuned to perform and handle like a low-slung sports car but here we are. And Audi executes this mystifying transformation as expertly as any carmaker in the automotive world.

Audi says the RS Q3 Sportback will blast from 0-100km/h in 4.5 seconds. Anything under 5.0 seconds is properly fast, and there's nothing quite like the deep-throated bellow of a VW Group in-line five to raise the hairs on the back of your neck.

The RS Q3's sport exhaust system is a dual-branch set-up with exhaust flap control, and people of a certain age will instantly imagine themselves matching it with Ari Vatanen, Walter Röhrl and Michèle Mouton on a suburban special stage behind the wheel of a 1980s Group B Sport Quattro rally car (actually, the school drop off at an infinitely more sensible pace).

The car weighs in at a not insubstantial 1775kg, but 480Nm, available all the way from 1950rpm to 5850rpm, means a near instant surge of fierce acceleration is always lurking under your right foot.

And the VW Group is on the pace when it comes to dual-clutch auto transmissions, from Porsche's 'PDK' and VW's 'DSG' to Lambo's 'DCT' and Audi's 'S tronic'.

The RS Q3's seven-speed unit is quick and positive, the wheel-mounted paddles ramping up the engagement factor.

The variable ratio, electrically-assisted steering is capital G Great. Well weighted and precise with reassuring road feel and the Alcantara trimmed wheel is a nice way to access it all.

Suspension is by struts at the front and multi-links (four) at the rear with adaptive dampers on-board.

Despite running on 21-inch rims, shod with high-performance 255/35 Continental PremiumContact 6 rubber, ride comfort is surprisingly good.

Dial in 'Comfort' mode via the 'Drive Select' system and the impact of even substantial bumps is softened off appreciably.

An ideal set-up would be the first 'RS1' short-cut Drive Select button set for Comfort suspension, with throttle, steering and transmission set to maximum attack and the second 'RS2' mode tweaking the suspension to track-day level, too.

Push on through your favourite set of bends and you can feel the electronic wheel-selective torque control system keeping everything under control. This car puts its power down through sweeping sections with fuss-free authority.

The RS-specific menu in the digital instrument cluster provides extra instrumentation in the shape of a power/torque display, G meter and lap timer. Fun!

The brakes are professional grade with big ventilated rotors all around and aluminium fixed calipers at the front.

But beware, the flip side of the RS Q3's quick steering response is a sizeable 11.8m turning circle. Take your time when parking.

The Q7 is a big beast, but it's not as intimidating to drive as you may think.

In fact, it's very easy to live with, if you don't mind managing its size in certain scenarios, such as finding a park in a busy shopping centre.

The SUV's electric power steering is speed-sensitive, which means fewer inputs are required at low speed, making parking and other manoeuvres easier, while stability is improved at high speed.

While not the first word in feel, this system is nicely weighted and surprisingly direct, endearing the Q7 with some sports-car characteristics.

That said, our favourite element is its independent suspension set-up, which consists of multi-link axles with air springs and adaptive dampers.

Needless to say, ride comfort is superb, with the SUV just floating along, even on uneven surfaces.

Introduce a coarse-chip road or a pothole, though, and the Q7 does become unsettled. But this is probably more noticeable because the ride is otherwise so sublime.

Instead, it's through the corners where it's truly exposed, with body control decent but nowhere near class-leading. Yep, it's here that its 2135kg unladen weight (excluding 75kg for driver and luggage) is really felt.

Flick the SUV into its Dynamic drive mode and things noticeably pick up, with extra heft added to the steering and the suspension firming up and hunkering down by up to 40mm. It's an improved experience in the bends, but not a memorable one.

However, our biggest bugbear is the exaggerated turbo lag served up by the 50 TDI's engine. Below 2000rpm, it has absolutely no go. Above it, though, it hammers.

Being a diesel unit, it doesn't have a lot of revolutions to play with, so you find yourself hunting for its upper reaches when accelerating, even around the town.

Making the most of the situation, the 50 TDI's smooth automatic transmission is responsive to kick-downs, but it's not lightning quick, meaning progress is stunted more often than not.

It also doesn't help that the eight-speeder is tuned for economy and therefore likes to keep engine speeds just above idle. This is particularly evident when attempting to power out of a corner.

When playing in the engine's upper reaches, the 50 TDI well and truly comes alive, serving up punchy acceleration, which is easier to access with the aforementioned Dynamic drive mode engaged. It makes shift patterns more aggressive and prompts more consistency.

ANCAP awarded the Q7 range (excluding SQ7) a maximum five-star safety rating in 2015.

Advanced driver-assist systems extend to autonomous emergency braking (with pedestrian detection), lane-keep and steering assist, blind-spot monitoring, rear cross-traffic alert, adaptive cruise control (with stop and go functionality), driver attention alert, hill-descent control, hill-start assist, tyre pressure monitoring, surround-view cameras, and front and rear parking sensors.

Other standard safety equipment includes eight airbags (dual front, front and rear side, and curtain), electronic stability and traction control systems, anti-skid brakes (ABS), brake assist and electronic brake-force distribution, among others.

Audi Australia covers all the models it sells with a five-year/unlimited km warranty with 24-hour roadside assistance included for the duration. Pretty much cost-of-entry in this part of the market.

Paintwork defects are also covered for five years, and the body is warranted against corrosion (to the point of perforation) for no less than 12 years. Nice.

Service intervals are 12 months/15,000km and capped-price servicing is available, a five-year/75,000km plan for the RS Q3 costing $3580, an annual average of $770. Fairly steep.

An 'Audi Advantage' package is also available, adding an extra two years' worth of warranty, scheduled servicing and roadside assistance (to the end of any existing term) for $3800.

All Q7 variants come with a three-year/unlimited-kilometre warranty, which is well short of the premium market's new five-year standard.

Audi also bundles in three years of roadside assistance, although this term can be extended up to nine years if the vehicle is serviced at an authorised dealership, which is nice.

Speaking of which, service intervals are every 12 months or 15,000km, whichever comes first. Capped-price servicing plans are available, costing $2310 for three years or $3190 for five.
