Cadillac Lyriq vs Audi Q8 E-Tron

What's the difference?

The Lyriq Luxury combines handsome styling and luxurious appointments with responsive yet supple ride quality, the choice of relaxed driving or exhilarating performance as desired and a decent driving range. Its lack of towing ability may be a deal breaker for some, but it's certainly worthy of consideration by prestige SUV buyers with a penchant for electric power and (for now at least) sub-$100K drive-away pricing.

The Audi Q8 e-tron ushers in welcome improvements to an already likeable and capable large luxury SUV.

But it is also feeling dated compared to newer and fresher rivals like the BMW iX, isn’t as good to drive as the best, offers disappointing range for the size of the new battery, and prices are creeping up for what is essentially a half-decade-old EV.

The name change isn’t enough. What the Q8 e-tron really needs is a massive leap in its Vorsprung durch Technik in a rapidly evolving electrified landscape.

 Very good… but far from great.

The Lyriq has a generous 3095mm wheelbase, is more than five metres long (5005mm) and almost two metres wide (1977mm, including mirrors). Its 1620mm roof height is relatively low for a large SUV, resulting in a sleek and sporty profile combined with a muscular surefooted stance fronted by a finely-etched solid grille.

It rides on five-link independent suspension with GM’s ‘passive plus’ dampers, plus there’s electric power-assisted steering and big Brembo disc brakes in each corner featuring classy Cadillac scripts on the calipers. Turning circle is 12.1 metres, which is to be expected for a car of this size.

The interior design is an elegant blend of soft-touch materials and discreetly textured surface finishes with an emphasis on chrome and satin chrome highlights. It’s also spacious as you’d expect, with the panoramic sunroof creating a bright and airy feel.

We applaud Cadillac’s adherence to tradition with physical buttons and knurled dials and knobs for controlling key cabin and driving functions, in preference to annoying and distracting touchscreen menus. There’s also nice attention to detail with small jewel-like Cadillac emblems and scripts contributing to its prestige look and feel.

The Q8 e-tron looks smaller than it actually is, with the SUV wagon’s length/width/height/wheelbase numbers measuring in at 4915/1937/1633mm/2928mm, respectively.

The Sportback version is slightly lower at 1619mm.

You’ll need a keen eye to spot the difference between the old e-tron and new Q8 e-tron, with almost all of the visual changes reserved for the front end.

For starters, there’s a new, two-dimensional four-ring logo that looks larger and flatter than before, sitting within a sleeker and slimmer grille treatment that now takes in the restyled headlights. Along with the redesigned bumper, the effect serves to broaden the SUV’s stance.

The effect also suggests improved aerodynamics, aided by small air foils near the wheel arches and a fully-clad underbody section.  

Otherwise, aside from the odd inclusion of the make-model name on the B-pillar and minor trim updates out back, the Q8 e-tron keeps the same, contemporary appearance of its predecessor. Which is no bad thing. 

And there are even fewer changes inside.

The Lyriq’s 2687kg kerb weight (largely due to its hefty propulsion battery) and 3200kg GVM results in a modest 513kg load capacity, which could easily be used up by five large adults before you could think about loading their luggage. It’s also not rated for towing in Australia which limits its appeal as a recreational vehicle.

Driver and front passenger enjoy palatial space and comfort plus ample storage with a bottle-holder and bin in each door. There's also a large glove box, pop-out drawer in the dash and a ‘floating’ centre console equipped with a lower tray, three USB-C ports, a 12V socket, wireless phone charging and a felt-lined box at the back with padded lid that doubles as an elbow rest.

The rear doors open wide for easy entry to the rear bench seat which even for tall people (I’m 186cm) offers ample room for knees and feet, enhanced by a flat floor with no transmission tunnel for centre passengers to straddle.

However, the top of my head brushes the roof lining and the unusually high floor height (we assume caused by the underfloor battery) results in raised thigh angles that concentrate more weight on the lower back.

Given the rounded lower backrest cushions, which integrate with the ISOFIX child seat anchorages in the outer seating positions, also protrude into a passenger's lower back region, the rear seat provides less than ideal comfort for tall passengers in contrast to the sublime luxury up front.

Even so, rear passenger storage is well catered for with a bottle-holder in each door, pockets on both front seat backrests and two cupholders in the fold-down centre armrest. The rear of the centre console offers two more USB-C ports, adjustable air vents and adjustments for numerous comfort settings.

The power tailgate provides access to the fully carpeted rear luggage area, which offers up to 793 litres (almost 0.8 cubic metres) of load volume with the rear seats upright and up to 1722 litres (almost 1.8 cubic metres) with the seats power-folded flat. This provides a versatile space for carrying everything from a mountain bike to flatpack furniture.

The luggage area also has four tie-down hooks, a 12V socket and a hinged floor section which when opened reveals an underfloor bin ideal for storing charging cables (see image).

More than merely good enough.

Entry and egress are easy thanks to a lofty ride height and wide-opening doors. Once sat, you’ll discover Audi has not changed anything much inside compared to the old e-tron. Frankly, very little needed to.

You’ll still find a strikingly stylish and upmarket cabin offering sufficient space for five people, a commanding driving position, superbly supportive front seats that are a boon when long-distance driving, plenty of storage options, ample ventilation and suitably moody lighting.

While not the most modern dash on the market when contrasted to the vast ‘hyper’ screens of some rivals, the Q8 e-tron’s remains very architectural in appearance and presentation.

Trim and material quality are certainly up to brand expectations. Practicality remains a priority, with lots of storage areas within the dash, console and door cards.

There are no fewer than three screens – a 12.3-inch digital instrument cluster Audi calls 'Virtual Cockpit', a 10.1-inch central multimedia display with haptic feedback and an 8.6-inch unit for climate control.

While they may seem daunting at first, a little familiarisation means most users will find them easy to operate.

Kudos, too, to the super-clear markings in the instrumentation, as well as the very satisfying tactile sensations of using the quality switchgear and controls. Typical Audi thoroughness here.

The same applies to the Q8 e-tron’s roomy and pleasantly-presented back seat area, with intelligently designed seating offering a nicely angled backrest as well as supportive cushion.

Three people can fit across without too much pain, though two is better, as the folding centre armrest and other amenities like air vents and climate control systems can be better-accessed and enjoyed.

You can see, smell and feel where your money’s gone inside. This is a quiet, isolated and cocooning experience, whether cruising on the motorway or stuck in heavy urban traffic. As you’d expect from a luxury SUV.

About the only real jarring aspect are the $3500 virtual exterior mirrors, created to improve aero performance. Their door-mounted screens are set low, outside the natural visual eyeline of the driver, creating confusion and adding precious extra seconds of eyes not on the road ahead. They’re irritating to the point of frustration.

Otherwise, the Q8 e-tron gets the job done inside, with cargo capacity at a reasonable 569 litres in the SUV wagon and 528L in the Sportback. And there’s even a 62L tub in the frunk up front to store the cables that also come standard with the EV.

Audi interior and packaging expertise strikes again.

First thing’s first. The Q8 e-tron has very little in common with the existing Q8 petrol, diesel and SQ8 high-performance models.

These, along with the larger Q7, have internal combustion engines.

However, keep in mind all leverage variations of the same 'MLB Evo' architecture that first saw the light of day all the way back in 2015. So, no spring chickens here.

But as it currently also serves Bentley, Lamborghini and Porsche SUVs, we’re talking about a classy set of components, anyway. Plus, the pre-facelift model was only rolled out on the world market in 2019.

For now, only a single variant is here, known as the Q8 e-tron 55, meaning the previous, smaller-battery 50 and flagship SQ8 aren’t here yet. That will happen sometime during 2024.

As before, there’s the choice of a traditional SUV wagon or more-popular BMW X6-style Sportback SUV coupe.

Prices start at $153,900 (all prices are before on-road costs) for the former and $165,900 for the latter, and that’s a jump of nearly $8K and $9K respectively over their old e-tron-as-a-noun-rather-than-an-adjective predecessors.

At least the Q8 e-tron is well equipped.

On the safety front, you’ll find about 40 driver assistance systems, backed up by a plethora of cameras, radar sensors and ultrasonic sensors to help keep the SUV as secure as possible.

These include a 360-degree camera system, adaptive cruise control, lane-support systems, rear cross-traffic assist and Autonomous Emergency Braking (AEB).

More on safety further down below.

All models also include adaptive air suspension with a variable ride height range of 76mm, a drive-mode selector that switches between normal and sport settings, LED headlights with auto high beams, keyless entry/start, front and rear climate control, heated and powered front seats and adjustable regenerative braking paddles on the steering wheel.

There's also a head-up display, three digital screens including electronic instrumentation and a central touchscreen with haptic feedback, satellite navigation, Android Auto, wireless Apple CarPlay, digital radio, wireless smartphone charging, four USB-C ports, an electric tailgate with gesture control, roof rails and 20-inch alloy wheels – with a space-saver spare wheel to boot.

Plus, an undisclosed number of Launch Edition SUVs from $165,900 are also available, adding Audi’s S line exterior styling touches, 21-inch wheels, sports front seats, a racier steering wheel, electric steering column adjustment and more.

Note that the base Q8 e-tron 55 does not include leather upholstery (it’s synthetic material instead) or a sunroof as standard.

Pricing and spec, then, are generally in-line with the luxury Euro EV SUV competition, which is to say, a bit on the exxy side.

Let’s check out the changes.

The Lyriq features drive units with single-speed transmissions located at the front and rear which provide permanent all-wheel drive. Each is equipped with an electric motor, which combined produce 388kW of power and 610Nm of torque. There are also numerous selectable drive modes. Claimed 0-100km/h acceleration time is a rapid 5.3 seconds.

Tech-overload alert. As per its predecessor, the Q8 e-tron 55 continues with two electric motors – one on each axle – for ‘quattro’ all-wheel drive.

Upgraded internals are said to improve efficiency substantially. Both are induction/asynchronous motors, mated to a single-gear two-stage ratio planetary transmission.

In the 55 model, the dual-motor set-up delivers a combined 300kW of power and 664Nm of torque, for a healthy 0-100km/h sprint-time of 5.6 seconds, on the way to a 200km/h top speed.

That’s impressive, given the lightest Q8 e-tron 55 tips the scales from 2595kg. That said, the Audi’s power-to-weight ratio is an equally strong 116kg/tonne.

Other updates include more direct steering, stiffer front suspension and retuned chassis controls.

Suspension is a five-link arrangement all-around, with adaptive air suspension featuring an electronically controlled with continuously variable adaptive damping system.

GMSV claims official combined consumption of 22.5kWh/100km and up to 530km of driving range from the Lyriq’s 102kW lithium-ion propulsion battery.

When we collected our test vehicle the dash display was showing 100 per cent charge and an estimated driving range of 583km.

We drove 239km over five days and still had 52 per cent charge and 300km of range remaining when we did an overnight charge at home using the supplied AC charger with a domestic three-pin plug.

However, after 15 hours the charge only increased from 52 to 65 per cent for just 76km of extra driving range, so we would recommend installing a dedicated wall box for faster home charging.

In total we covered 297km across our usual mix of suburban, city and highway driving with average energy consumption just under the Cadillac's official figure, so based on our test results a driving range of around 500km per charge is credible.

GMSV claims 7.4kW AC charging can add up to 43km of range per hour, which increases to 94km with 22.1kW charging. And up to 128km of range can be added in just 10 minutes using 190kW DC fast charging.

The good news is that the lithium-ion battery pack size rises from 95kWh to 114kWh, and is accompanied by faster DC charging capability, due to a jump from 150kW to 170kW.

While far from the class best, this cuts down charging times by a considerable margin.

The claimed driving range is 454km, while average consumption is a disappointing 25.6kWh/100km. The Q8 e-tron’s trip computer during our run in it recorded a mid-to-high 20s readout, by the way.

The driving position is supportive and comfortable with multiple power-adjustment of the seat and steering wheel ensuring people of most heights and girths can enjoy luxurious travel.

The low dashboard height ensures vision to the front of the bonnet and its array of physical buttons, knurled dials and knobs minimise touchscreen use, which makes driving far less distracting than having to search through digital menus.

It’s very quiet given its electric drivetrain. Most noise emanates from the tyres but that is also minimised by the audio system’s noise cancellation technology and the cabin’s effective acoustic insulation.

Ride quality and handling are excellent thanks to the Lyriq’s suspension refinement and close to an ideal 50-50 weight distribution mostly influenced by the positioning of its drive battery.

This battery’s considerable heft (we reckon it weighs at least half a tonne) also creates ample sprung weight to assist the suspension in smoothing out bumps and its underfloor location ensures a low centre of gravity for surefooted cornering.

Standing start acceleration is more than impressive for a luxury car weighing almost 2.7 tonnes, with instantaneous torque from its two electric motors helping to propel the Lyriq to a neck-straining 100km/h in about five seconds.

This spirited response creates a sporty and engaging drive that belies the vehicle’s weight, particularly in Sport mode with its sharper throttle response and firmer steering feel.

We also like the choices for regenerative braking which include ‘One Pedal Driving’ mode with 'Normal' and 'High' settings, both of which make the quartet of disc brakes largely redundant (the High setting feels like heavy pedal braking) while optimising battery charge. There’s also a small paddle on the steering wheel which increases regenerative braking in response to the amount of finger pressure applied to it.

Our only criticism from a driver’s point of view is the absence of a head-up display (HUD) and traffic sign recognition (TSR), both of which are notable omissions for a prestige vehicle in this price range.

For decades, Audi used the advertising tagline ‘Vorsprung durch Technik’ – which means Progress through Technology in its native German – to highlight how advanced its vehicles are.

So, how has the Q8 e-tron advanced over its predecessor?

Right from the get-go, there’s so much to dig about the electric Audi SUV, especially if you’re new to luxury EVs.

To start with, it’s as quiet as you’d expect, even by luxury brand standards. As the Audi accelerates, the sense of momentum is somewhat masked by how refined and civilised your progress is.

Watch that, though. You could get a speeding fine more easily than you expect!

Anyway, with 664Nm of torque coming on instantly, there’s certainly no shortage of it, backed up by enough muscle for effortless and instantaneous overtaking. This sort of motoring can become highly addictive.

Similarly, a low centre of gravity, combined with a beautifully modulated electric power steering and the quattro AWD set-up, provides pleasing agility combined with reassuring roadholding. Even when you’re pressing on, the Q8 e-tron corners and grip with confidence and control.

So far, so good. Especially considering the air suspension is further cushioning your sense of speed, with excellent bump absorption for an isolated ride.

That’s on the standard 20-inch alloys spec. Riding on the larger wheels, there is a bit more firmness, as well as some road-noise intrusion.

Plus, it doesn’t take long to realise the Q8 e-tron is a very heavy vehicle. Though undeniably quick and athletic, changing directions in a hurry means that the SUV can feel a bit unwieldy.

Throttle response at higher velocities can seem a little muted and, over certain crests and humps when travelling fast, there is a sense that the driver really needs to have their wits about them.

Best to take it a bit easier, then, and enjoy the serenity the Audi EV SUV delivers in more typical and restrained travelling scenarios.

There is so much that the Q8 e-tron brings, and driving it normally really does reveal a sophisticated, comfortable, dependable and high-quality grand-touring experience.

Push a bit harder, though, and some cracks show up.

Tested way back in 2019 but updated in September, 2023, the e-tron/Q8 e-tron range scored a maximum five-star ANCAP crash-test rating.

There is no shortage of safety equipment – with passive and active, driver-assist-heavy technologies designed to avoid an accident, with full surround-view cameras also providing an extra level of security.

Standard kit includes Audi’s 'Pre-Sense front' and 'Pre-Sense rear', offering AEB, cross-traffic alert and active lane-keep assistance tech, as well as adaptive cruise control with full stop/go, eight airbags (dual front as well as side and curtain airbags for all outboard occupants), hill-descent control, anti-lock brakes, electronic brake-force distribution, brake-assist, electronic stability control, traction control and tyre pressure monitors.

The AEB system can detect pedestrians and cyclists between 10km/h and 85km/h, and even at night, while for other motor vehicles that increases to 250km/h (an upper velocity more relevant for the coming SQ8 e-tron). The active lane warning operations is from 65-250km/h.

Both outboard rear seats feature ISOFIX child-seat latches, along with three top tethers for straps.

The Lyriq comes standard with a five-year/unlimited km warranty including five years' of roadside assist, while the propulsion battery is covered by a separate eight-year/160,000km warranty.

Scheduled servicing is every 12 months/12,000km whichever occurs first, with costs for the first five years of scheduled servicing or five scheduled services included in the vehicle’s purchase price. These servicing terms are generous for this segment, although some rivals offer similar enticements like Audi’s six-year ‘complimentary’ servicing for its Q8 e-tron.

GMSV has a national network of 45-50 dealerships across most capital cities and some regional areas but not all offer vehicle servicing.

Audi provides a five-year/unlimited kilometre warranty as well as six-years’ worth of free roadside assistance, which is nothing unusual these days, while the battery warranty is eight years or 160,000km.

The first six years of scheduled servicing is free, too. Intervals are every two years/30,000km (whichever comes first).

Plus, owners also receive six years of complimentary access to Chargefox’s network.
