BMW X Models vs Audi RS Q3

What's the difference?

If a BMW X3 is for you, then we have no quarrels with that. It’s a better all-round vehicle than the one it replaces and represents better value. And even though BMW mandates a hybrid driveline, there are still some significant choices within that framework.

By all means buy the M50 if you crave the rush of acceleration that almost 300kW can provide. And if efficiency is your altar of choice, then the plug-in 30e makes a lot of sense, too.

But even if you can afford either of those two more expensive variants, whatever you do, don’t dismiss the entry-level 20 model. At least drive it alongside the others and then make a decision based on all the facts, and not the assumption that entry-level equals the car you afford rather than the car you want.

It might be cheaper, but there’s absolutely no doubt that the 20 model is the one that shines and arguably makes the most of the opportunities BMW’s latest tech offers.

Sometimes less really is more.

Note: CarsGuide attended this event as a guest of the manufacturer, with accommodation and meals provided.

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.

It might be badged an X3, but this is no small vehicle. In fact, it’s bigger than the original BMW X5 (which set the tone for this entire market segment) with a length of 4755mm (4667mm for the first X5) and a width of 1920mm (1872mm). That said, it’s 25mm lower than the outgoing X3 in a move to emphasise its sportiness. Shorter it may be, but it’s also 16mm wider on the front track and 45mm wider on the rear than the outgoing model.

BMWs latest styling cues also appear in the new car, including the large, split-kidney grille that, for Australian-delivered cars, is also lit around its edges. The short overhangs that characterised the original X5 (and soon characterised this whole BMW genre) remain, and the T-graphic LED tail-lights round out the stylistic touches.

The other thing we noticed (and we’ve seen it on other cars recently) is a panoramic sunroof that doesn’t actually open.

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.

Cabin space is plentiful in the X3 with loads of room in the front, possibly thanks to the dashboard that is pulled back from you with only the twin screens and steering column offering themselves up to the driver. Even the air-vents are somewhat hidden. There’s good vision out and the seats themselves are lovely. The step into the cabin feels to be at just the right height, too; not too high, not too low.

Rear seating is good, too, although the X3 will always be better as a four seater than five thanks to the shape of the rear bench, but the glass roof opens the space up and there’s plenty of charging points and storage nooks. The sun blinds on the rear-side windows of the more expensive versions should be standard kit on every car sold in Australia.

We’ll take exception to the new gear-selector which doesn’t have a defined Park position and instead relies on applying the park-brake to engage Park. But the ambient light and contrasting cabin colours are a bit of a breath of fresh air.

There are levers in the cargo area to quickly fold the rear seats (60:40) at which point luggage space jumps from 570 litres in the mild hybrid cars to 1700 litres. The battery-pack of the 30e model means that luggage space starts at 460 litres and can be expanded to 1600 litres.

The latest version of BMW’s sometimes controversial iDrive operating system is simpler and easier to use than before and supported by a new operating system, but there’s still some familiarisation necessary. One improvement has been the addition of QuickSelect which works somewhat like the old favourites button system and gets around the need to drill into menus to access the functions you want.

A head-up display is a terrific addition, although where some displays are more tolerant of polarised sunglasses, the HUD in the BMW didn’t like mine and went dark at the most inconvenient angles.

None of the X3 variants feature a spare tyre of any sort. The 19-inch tyres on the base grade are run-flats, while everything else gets a repair kit for roadside emergencies.

If you want to tow, the good news is that all X3 variants can do so. But you will need to purchase the $2200 towing package which enables the X3 to haul a trailer weighing up to 2000kg with a maximum tow-ball down-weight of 200kg.

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...

The Audi RS Q3 Sportback edition 10 years is priced at $102,900, before on-road costs, which is a $3800 premium over the standard issue version.

For those extra dollars the car is upgraded with specific 21-inch black alloy rims, black badging and brake calipers as well as (three-stage heated) 'RS' Nappa leather-trimmed sports front seats with contrast 'Copper Honeycomb' stitching.

The fancy stitching extends to the Alcantara-trimmed steering wheel and gear lever, the RS floor mats also feature copper highlights and the door downlighting projects a unique rhombus design.

At that money the RS Q3 lines up against BMW's firecracker X3 M40i ($126,800), the ferocious Mercedes-AMG GLA45 S ($121,900) with the Jaguar E-Pace 300 Sport AWD ($84,500) the only other similarly pitched compact performance SUV within $20K of the Audi.

And as well as the performance and safety tech covered later in the review, the RS Q3's standard features list includes, three-zone climate control, adaptive cruise control, keyless entry and start, Nappa leather trim, ambient lighting (with 30 colour choices), an RS sport contour leather-trimmed steering wheel, 12.3-inch digital instrument cluster, 10.1-inch multimedia display (with text and voice control), (wired) Android Auto and Apple CarPlay, sat nav and wireless device charging.

There's also a Bang & Olufsen '3D Sound System' (15-speaker with 680-watt, 16-channel amp), digital radio, 21-inch alloys, electronically-controlled adaptive dampers, auto Matrix LED headlights (with RS-specific darkened trim) and a hands-free power tailgate. And it's worth noting metallic and pearl effect paint finishes are offered at no extra cost.

Pretty impressive. Especially when you consider even this special edition RS Q3 is $20,000 cheaper than its primary BMW and Merc-AMG rivals.

Hybrid tech across the board is the key phrase here, with the base-model 20 xDrive fitted with a mild hybrid electric motor and battery pack that works in conjunction with the 2.0-litre, turbocharged petrol four-cylinder engine. Power is 140kW and torque 310Nm. Like most mild hybrids, the electric motor offers power regeneration during braking, a mellow (by EV standards) kick in the pants during take-off and acceleration and also acts as the car’s starter motor.

The performance flagship, the M50 xDrive taps into the same technical philosophy with a mild hybrid augmenting the turbocharged six-cylinder inline petrol engine. In this case, however, peak power is a hefty 293kW and torque maxes out at 580Nm.

The most technically adventurous X3 is the 30e xDrive which uses plug-in hybrid tech to offer a claimed 91km of electric driving, about twice that offered by the original X3 PHEV it replaces. When the same 2.0-litre four-cylinder petrol as fitted to the 20 xDrive, and the electric motor are humming along together, there’s 220kW of power and 450Nm for the taking. The PHEV X3 can run in purely electric mode at up to a claimed 140km/h.

All variants use BMW’s familiar eight-speed automatic transmission and in each case, drive is sent to all four wheels on a permanent basis. Interestingly, the 30e and M50 versions package their electric motor as part of the engine-transmission combination. The 20, meanwhile, places its electric motor externally, as part of the drive-belt rotating assembly.

The M50 model has an M button that unleashes the full performance with one touch, and features an electronically locking rear differential in the interests of high-speed turn-in.

Adaptive suspension that varies the degree of damping is also part of the package on each X3 variant.

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.

As you might expect, the PHEV 30e model is the efficiency superstar of the X3 line-up with an official combined test figure of just 1.6 litres per 100km and 38 grams of CO2 per kilometre. The four-cylinder 20 xDrive is not bad for its size at 7.5L/100km (and 171g), yet the bruising six-cylinder M50 version with all that performance is not too far behind with an official figure of 8.2L/100km (187g).

The 30e PHEV features a selectable battery-saving mode as well as the option of forcing EV-only running. It features a 19.7kWh battery and BMW claims it can charge using a three-phase, 11kW socket from empty to full in two hours, 15 minutes. It does not make use of fast-chargers.

Exactly how far you’ll travel in the PHEV model will depend hugely on how and where you drive. On long, open road journeys, fuel consumption won’t be much different to the others, but with just a 50-litre fuel tank, it’s range won’t be stellar. But in urban running where the batteries are being recharged for free as you brake, the difference will be significant. Meanwhile, with a 65-litre fuel tank in the mild hybrid grades, the theoretical range (based on the official fuel number) is 865km and 765km for the 20 and M50 respectively.

While BMW recommends premium fuel for maximum efficiency, it also says that each X3 variant will not be harmed by the use of standard ULP if that’s all you can get hold of.

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.

Big heavy SUVS like this one haven’t always been too dainty on their feet. The extra bulk and height mean suspension has to be firmer, the big wheels and subsequent loss of tyre sidewall depth plays against ride quality and before you know it, the compromises have piled up and the driving experience has gone to hell.

This time, however, BMW’s claim that the X3 was designed from the start as an SUV and not converted from a sedan platform seems to hold water. There’s an overall greater sense of cohesion in the way the car steers and flows through corners and faster bends. The steering feel and feedback are a big part of that, too, and the whole seems at least as great as its parts.

The M50 is, predictably, a rocket with loads of accessible acceleration and a great noise while you’re enjoying it. That said, the 21-inch wheels and tyres don’t do anything for ride quality, but it remains an entertaining performance car in a familiar, ICE kind of way.

The plug-in is also perky with its 220kW on tap, but it’s less old-school and more techy. And while you can’t pick the point at which ICE hands over to electric and vice-versa, sensitive drivers will absolutely know that there’s a big dollop of electrical assistance when your right foot starts asking the tough questions. It definitely feels more overtly hybrid, though that shouldn’t be any kind of surprise, purely because that’s precisely the case.

Which brings us to the 20 entry-level grade. And while it’s going to be a controversial statement, this emerges as the most cohesive, rounded variant of the new X3. There’s something in the way the fizzy, bubbly (but very smooth) 2.0-litre four-cylinder provides more than enough urge, but never threatens to dominate the dynamics.

With less weight over the front wheels than the M50, and less weight overall than the PHEV, the 20 corners flatter, steers more intuitively and is simply more fun more of the time. Even on the optional 20-inch tyres, it rides better than the others, too, and might even be better again with the standard 19s other than the fact that those are run flats and we didn’t get try them.

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.

Although the Audi Q3 received a maximum five-star ANCAP score in 2019, the RS Q3 was specifically excluded from the assessment, so it's officially untested.

But the car boasts an extensive active (crash-avoidance) safety suite including, auto emergency braking (AEB) (5.0km/h to 85km/h for pedestrians and cyclists and up to 250km/h for vehicles), adaptive cruise control (with stop-go function and active lane assist), lane change warning and lane departure warning (with lane keeping assist).

There's also 'Attention Assist' (warning tone and visual signal if the system determines the driver's attention may be lapsing), front and rear parking sensors, a reversing camera with 360-degree view, rear cross-traffic alert, tyre pressure monitoring, 'Hill hold assist' and hill descent control.

If, despite all that, a crash is unavoidable there are six airbags on-board (front and side for the driver and front passenger as well as full-length curtains). The RS Q3's showing its (10-year) age here because additional rear side and front centre bags are close to the norm now.

Nice to see a first aid kit and warning triangle included and there are three top tethers and two ISOFIX anchor points for securing baby capsules and child seats across the second row.

BMW’s warranty on the X3 is the company’s usual five-year/unlimited kilometre deal. But in this case, there’s also a six-year/100,000km warranty on the high-voltage battery.

Also typical for BMW is the service interval which is not a set time or distance and instead is determined by how the car has been used. It’s called condition-based servicing and it’s nothing new at BMW.

There’s also capped-price servicing available. For the X3, the five-year/80,000km service package is $2475.

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.
