Audi Q4 E-Tron vs Subaru Solterra

What's the difference?

Audi is famous for sticking doggedly to front-wheel drive and quattro AWD, but clearly, when it puts its mind to it, the few RWD machines it has produced over its 116 years have been exceptional.

While not as exciting as the R8 or as supersonic as the e-tron GT, the Q4 e-tron is an impressive machine. Thoroughly engineered and thoughtfully designed to be a friendly, refined, comfortable, safe and capable family SUV, it deserves to be on your shortlist.

With a couple of choice option packages, the base 45 seems remarkably complete, but there’s plenty to enjoy in the hot-shot 55 quattro as well. Either way, Audi seems to be on a winner.

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

The updated Subaru Solterra is now good enough to compete with rivals such as the Tesla Model Y and Zeekr 7X. The price is right as are the driving range and motor outputs.

There's room for improvement in terms of cabin packaging. The car doesn’t cater for taller, larger people up front, with the steering wheel placement and wide centre console. Cabin storage could also be much better.

Still, the Solterra is superb to drive. One of the best EVs I’ve piloted at this price.

Whether talking about the SUV or Sportback, the Q4 e-tron is an excellent example of Audi’s recent design prowess.

Beautiful proportions, crisp surfaces, exquisite detailing and undeniable elegance are all present in spades. And the Sportback is a rare example of a graceful-looking coupe SUV, though it is not in the otherworldly Polestar 4’s league aesthetically.

However, where is the originality? You’d never know these are rear-motored and predominantly RWD vehicles. Yes, the Single Frame grille execution is amongst the best-yet from the brand, while the wheelarch ‘blisters’ are an (albeit questionable) homage to the seminal Ur-Quattro of the 1980s, but the Q4 e-tron could be any contemporary Audi SUV from the Q3 up. Its design is the opposite of daring.

Still, maybe the Q4 e-tron’s classy, relatable conservatism explains why the Brits made this car their second-best selling EV of 2024, representing everything that the number one Model Y is not.

Plus, with current global automotive interiors stalling behind over-illuminated and oversized screens full of greasy fingerprints, glitchy electronics and reflections of their frustrated operators, a bit of old-school Audi cabin presentation knowhow can only be a good thing, right?

The Solterra is a mid-sized SUV with sporty coupe-like styling and this update has seen the front of the car receive a new look which to my eyes is better than the previous face. 

The rest of the car’s exterior remains mainly unchanged in the design.

If you aren’t a fan of the Solterra’s look then check out Toyota’s bZ4X, which is its twin and has slightly more conservative styling, and while I do like the Subaru’s face, I think Toyota’s tail-light treatment is cleaner.

The cabin is modern with a large central media screen, a high-placed instrument display and a wide centre console with dual phone chargers. But the squareish steering wheel steals the show, completing the futuristic vibe.

This update has seen the centre console re-designed with the dual chargers added and the gear-shifter moved backwards away from the media display.

The cabin doesn’t have much in the way of glitzy touches, with dark materials dominating throughout. Hard plastics abound, but the interior still looks and feels premium.

Unlike most of its German competitors (and the Volvo EX40), the Q4 e-tron is built on a dedicated EV platform known as MEB, and shared with other Volkswagen Group models, like the Skoda Enyaq and Volkswagen ID.4.

Consequently, the Audi feels a wee-bit narrow inside, as the MEB SUV family are on the smallish side for medium-sized SUVs. This is not a criticism, just an observation.

And there is no lack of interior space, either. Entry/egress is easy via large doors, there’s plenty of space for heads and shoulders and legroom is generous. All are an upshot of the EV-only platform.

Despite some obvious packaging links with the other VW MEB interiors, the dashboard is very Audi-esque in styling, layout, functionality and quality.

From the ‘Virtual Cockpit’ electronic instruments and crisp multimedia screen, to the feel of the buttons and logical, easy locations of the controls, the Q4 e-tron is completely and utterly on-brand. And that means high standards. Looks posh. Works well. Nice to touch. No bewildering endless screen-menu search and rescue frustration here.

Plus, the Audi is practical. We’ve already talked about ample room, but even the standard, non-sports seats cosseted and supported over a few hours of testing; different and unexpected levels of storage (including a nifty bottle holder ahead of the forward door jam – brilliant); superb ventilation and, especially in the Sportback 55 e-tron quattro sampled, a banging audio system, complete a suave and sophisticated interior experience.

Issues? No too many, really.

There is quite a lot of quality plastic material visible, which might offend some sensitive souls. There is some road-noise intrusion over coarse surfaces, perhaps reminding owners of the Q4 e-tron’s shared architecture; and rear vision in the Sportback is hampered by fat pillars and slim back glass.  

However, no spare wheel exists. Nada. Just the occasionally ineffective and always-infernal tyre inflation kit, that renders the tyre and kit useless afterwards and so makes for expensive replacements. And just because almost everybody else does it, this is not good enough for Australia.

The corollary of that is quite generous luggage capacity, with the Sportback’s 535 litres somehow beating the more-upright SUV’s 520L VDA capacity, though with the rear seatbacks folded that switches to 1460L and 1490L respectively. Both are gorgeously lush and quite practically shaped.

And what about the storage compartment up front?

The steering wheel’s square design is like that for a reason - it’s designed to provide the driver with a clearer view of the instrument cluster. But as noted in the past with other vehicles that choose this set up, the ergonomics don’t work for everybody - especially if you’re tall like me (I’m 189cm).

In my case the top of the steering wheel obstructs my visibility of the display, which shows vehicle speed among other crucial info. 

There’s also a problem with the clearance of the steering wheel and my legs. This is caused by a combination of my height, the low steering wheel and the limitations of how much it can be raised, the low-hip point in the seating position and the shape of the wheel. 

Add an overly wide centre console and space for larger and taller drives becomes even more cramped.

Moving the shifter back in this update also makes it more difficult to use for me and the mechanism is quite clunky.

Second row space is a much better story, with a flat floor, good headroom and lots of legroom even for me behind my driving position. The rear door aperture isn’t great and this has made installing child car seats and the corresponding child difficult.

Cabin storage could also be better. There’s no glove box, but there is space under the centre console, although this is now where the large driver’s manual lives. There’s a large centre console bin, big door pockets and four cupholders (two up front and two in the second row).

The second row has directional air vents and USB ports. There are USB ports up front, too.

Boot capacity isn't enormous at 421 litres in the entry-grade and 410 litres in the Touring. There’s no front boot, either. Under the bonnet is the Solterra’s front motor and electrical hardware.    

The Solterra is a five seater SUV, so no third row here.

The updated Solterra is offered in two grades. An entry-grade model, simply called Solterra, lists for $63,990 and above that is the Solterra Touring for $69,990. That’s up to seven thousand dollars more affordable than pre-update.

We tested the top-of-the-range Touring, which comes loaded with standard features, the only option being leather seats.

If you were wondering if you needed to spend the extra money on the Touring you might be pleased to know both grades have exactly the same powertrain and the entry-grade comes with plenty of standard features.

Coming standard on the entry grade Solterra are 18-inch alloy wheels, LED headlights and LED tail-lights, power mirrors, puddle lamps, a powered tailgate with kick-sensor (new with the update) and roof rails. 

There’s also synthetic leather seat trim, heated and eight-way power-adjustable front seats, a heated leather steering wheel, heated second row seats, dual-zone climate control, a 14-inch multimedia touchscreen (new) and 7.0-inch driver display, wireless Android Auto and Apple CarPlay, dual wireless phone chargers (new) and a six-speaker sound system.

The Solterra Touring comes standard with all this but adds 20-inch alloy wheels, a panoramic sun roof, ventilated front seats (new) and a 10-speaker Harman Kardon sound system.

The Touring also features a 220V vehicle-to-load (V2L) power outlet.

Unlike the Model Y, there's no storage up front. That space is instead reserved for auxiliaries and, in the 55 quattro versions, the second electric motor that drives the front axle for AWD.

In all versions, a permanently excited synchronous motor sits on the rear axle driving the rear wheels via a single-speed transmission.

Tipping the scales at 2145kg, the 45s produce 210kW of power, to offer a power-to-weight ratio of 98kW per tonne, while the 2235kg 55s’ 250kW output ups that to 112kW/tonne. Both Q4 e-trons deliver a healthy 545Nm of torque.

No slouch, the 45s manage the 0-100km/h sprint in a rapid 6.7s, while the 55 quattro’s extra motor chimes in when extra traction is required, shaving another 1.3s off that, for a 5.4s time. Top speed in both is limited to 180km/h.

Adding a bit more driver involvement, the 55s have variable ratio steering, while MacPherson-style struts up front and a four-link independent rear suspension setup out back help keep everything under control.

The Solterra has two electric motors and as before there is one driving the front wheels, and one driving the rear wheels for all-wheel drive. Toyota’s bZ4X twin can be had in two-wheel drive and AWD.

The big news is the motors are now more powerful. Much more powerful. Combined output is 252KW (up from 160kW). That’s a huge increase but power is still less than the output of a Model Y or Zeekr 7X.

The front motor now makes 167kW/268Nm, while the rear motor produces 88kW/169Nm. Acceleration from 0-100km/h is about five seconds and that’s almost two seconds faster than the old version. 

Built on a 400V architecture, the Q4 e-tron uses an 82kWh Lithium-ion battery pack, offering a useable capacity of 77kWh. It only charges to 80 per cent full to help preserve battery life.

Now, driving most of the available versions over a 200km launch route from Adelaide airport to wine country, we averaged between 17.5 and 19.5kWh/100km, with the lighter RWDs obviously being the more economical of the drivetrains.

In ascending order, the official combined average figures are 16.9kWh/100km (Sportback 45), 17.4kWh/100km (45 SUV), 17.5kWh/100km (Sportback 55 quattro) and 18.1kWh/100km (55 quattro SUV).

Despite weighing about the same, the Sportback uses around 0.5kWh/100km less electricity than the SUV version, due to better aerodynamics.

That translates to about 15km of extra distance, with the Sportback 45 going the furthest, delivering a WLTP range of 540km. That’s followed by the 45 SUV, Sportback 55 quattro and 55 quattro SUV with 524km, 503km and 488km respectively.

To aid with recharging, the driver has three modes of battery energy recuperation via steering-wheel paddle shifters.

Plugged in at home, the battery needs about 40 hours to completely recharge, or over 12 hours using an optional 7kWh Wallbox. Maximum AC charging capacity is 11kW.

With a maximum of between 135kW (RWD) and 175kW (AWD) of DC charging capacity, however, 10-80 per cent charge using a 50kW DC public charger needs fewer than 70 minutes, or just 40 minutes if you find a 100kW station.

The updated Soltera’s battery size has increased to 74.7kWh. That’s up from 71.4kWh and means driving range has increased. 

The new, larger lithium ion battery delivers a range of 566km (WLTP) in the entry-grade Solterra (up from 414km). That addresses a big concern about the old car. The Touring has a range of 517km and any range above 500km is acceptable in my book.

Also big news is the increase in maximum AC charging capacity from 11kW to 22kW. DC charging capacity is the same at 150kW with 0-80 per cent charge in about 30 minutes.

Consumption officially ranges from about 14.6kWh/100km in the entry-grade Solterra to 16.0kW/100km in the Touring. The Touring we tested was reporting 17.0kW/100km according to the trip computer after 163km of testing in mainly urban conditions. 

Audi might be late to the affordable electric SUV party, but it’s certainly been worth the wait from behind the wheel, because the Q4 e-tron drives exactly how you would expect an Audi to.

The 45 in either body shape has ample oomph, as its impressive 6.7s 0-100km/h times prove, providing a decent amount of instant speed the moment you put your foot down. This is a smooth, strong and muscular performer.

The steering is nicely modulated and precise, for easy, flowing handling, even when the speed is taken up a few notches. Note that while it may seem a little light, it can be configured for a more dynamic feel.

However, slightly stronger single pedal braking would be appreciated. The Audi EV’s brakes do a great job stopping the car, but they do feel a bit on/off at first. Maybe even a bit wooden.

All the Q4 e-trons we drove on the launch around the Adelaide hills rode on steel springs. That said, and to our surprise, the suspension is more than comfortable enough, soaking up many of the bumps we encountered without breaking a sweat.

Plus, except on coarse bitumen, there's not much of any type of noise coming through inside the cabin. These are agreeably comfortable and refined cruisers.

Meanwhile, the 55 quattro version is a slightly different proposition, with measurably stronger acceleration across the board and more eager throttle response. Actually, even on bone-dry roads at the height of summer, there’s almost too much torque coursing through the axles, so just be wary of this EV’s considerable power.

Still, the twin-motor Audi feels like a relaxed yet brawny grand touring SUV, with plenty in reserve for fast overtaking and quick getaways. Even the RWD model provides exceptional roadholding and control, but that extra AWD grip when things become a bit slippery would certainly be a bonus.

Plus, kudos to the Germans for delivering user-friendly driver assist safety systems. Nuanced and largely unobtrusive, they keep you safe without driving you to distraction. China and Polestar in particular, are you listening?

On the flip side, you do feel the extra weight of the second electric motor (about 100kg more), and so it doesn't quite have the agility and alacrity of the standard 45 RWD machine.

Indeed, there isn’t quite the athleticism or connection of driver-focused alternatives (like BMW), but the Q4 e-tron rarely puts a foot wrong, either.

Impressively capable and dynamic, Audi’s more-affordable electric SUV has been worth the wait.

The Solterra may slightly lag behind rivals in some areas such as range and power output, but where most rivals can barely touch it is when it comes to driving.

Currently there aren’t many electric vehicles that are good to drive, except for more prestige offerings from brands such as BMW, Mercedes-Benz and Porsche. 

The Solterra is one of the best electric vehicles I have driven at this price point and it’s down to the outstanding platform it shares with the Toyota bZ4X which provides superb ride comfort, great handling and excellent steering.

Acceleration is strong and traction from the all-wheel drive is good.

Sure, while the driving position needs improvement, the car itself is excellent to drive.

Visibility is also good and sound intrusion is minimal. We noticed some materials making noises in the cabin. Although this is common, with no engine to mask it, it becomes more noticeable in EVs. 

The Solterra has been awarded the maximum five-star ANCAP rating - but that was given under 2022 testing criteria and the bar has been raised quite a lot higher since then. 

Still, the level of safety technology is high with AEB, lane keeping assistance, blind spot warning and rear cross traffic alert onboard. 

Front and rear parking sensors are standard on both grades, as is a 360 degree camera view. Auto parking is standard on the Touring.

A digital rear vision mirror is also standard on both grades providing a clear and unobstructed view.

There are seven airbags present, including a front centre bag. And there are three child seat top tether points across the second row with ISOFIX anchors in the two outer positions.

Audi’s warranty remains the same as before, at five years with unlimited kilometres, with the battery covered for eight years or 160,000km. Six years of roadside assistance is also included.

Service intervals are every two years or 30,000km. Nothing special here nowadays.

But the Q4 e-tron owner can buy a six-year service plan for a total of $2050, while gaining 12 months of free electricity at Chargefox stations. They can also purchase a JET Charge home installation charger from $800.

The Solterra is covered by Subaru’s five-year, unlimited-kilometre warranty which is falling behind the seven-year warranty offered by many now. The battery is covered  by an eight-year, 160,000km warranty. 

There is also five years of capped price servicing with each yearly/15,000km service costing between $130-$300. That’s a very reasonable price.
