What's the difference?
Chevrolet’s Corvette Z06 supercar is an all-American answer to European rivals Lamborghini and Ferrari, but it’s not just this that makes it so appealing.
Spending a week with the most potent Corvette you can get in Australia has left me with a list of notes on this beast I want to hand over to you. Maybe it will help make your mind up about it or change your mind.
What makes the Z06 the flagship of the Australian Corvette range isn’t little luxuries, but seriously upgraded mechanical hardware, much of it track focussed.
Our test car was also fitted with the Z07 Performance package which adds a carbon-fibre aero kit to pin the Corvette down at high speed while also drawing everybody’s attention to it.
Oh, and then there’s the sound of the largest flatplane crank V8 ever to go into a production car… and look out for your ankles - let me explain…
It can be easy to dismiss electric cars as an imperfect solution to the world’s problems. But that would be missing one big point - they’re really, really fast.
Carmakers twigged that not everyone was enamoured with the environmental credentials of electric vehicles (EVs), especially luxury brands, and thus pivoted to the new sales tacit of performance and prestige.
Which is why Audi’s current performance flagship vehicle is not a mid-engined V10-powered replacement for the R8, but rather the all-electric RS e-tron GT. And for the new model year they have not only updated the range, bringing (you guessed it) more power, but also added a new hero model - the RS e-tron GT Performance.
It leads a new three-pronged line-up for the four rings brand, with the RS e-tron GT Performance sitting above the RS e-tron GT and the new S e-tron GT; the latter effectively replacing the previous ‘entry-grade’ model known only as the e-tron GT.
These arrive as part of a mid-life update for the model, with some minor styling tweaks (inside and out) along with enhancements to the battery and changes to the specifications.
The new range has just arrived in Australia and Audi will be hoping it can turn around the sales performance, which saw the outgoing e-tron GT and RS e-tron GT find just 84 customers in 2024. That was a decline of 75 per cent on 2023 sales, and nearly 200 less than the closely related Porsche Taycan.
The Chevrolet Corvette Z06 is truly a supercar offering outstanding dynamics for a lot less money being asked by European rivals - just make sure it's not your only car for those times when you're in a hurry.
While it may be a very different beast to the R8 supercar, it’s hard to argue that the e-tron GT offers performance that isn’t equal to anything Audi has previously produced. The immense acceleration and power, coupled with the brilliant and clever handling make this updated range, especially the RS pair, feel like something special.The fact that it will save you visiting a petrol bowser and might help cut harmful emissions is just a bonus.
Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.
We’re talking about the closest thing to a real-life Hot Wheels car here. See, while Ferraris look elegant to me like expensive jewellery, Lambourghinis like cheese graters and McLaren’s look like slippery alien spacecraft, the Corvette Z06 looks exactly like an American supercar should - an unapologetic, ludicrous beast. And I love that.
Dialing up the wild is that enormous carbon wing and front splitter with dive planes thanks to the Z07 package. Just a word of warning, though, the front splitter and dive planes stick out not just visually, but in the sense that I walked into them often and my ankles still have the scars.
I can’t recall the last time I drove a car with carbon-fibre wheels either - these are the biggest rims fitted to a Corvette and they’re wrapped in Michelin Pilot Sport Cup 2R ultra performance tyres (275/30ZR20 front and 345/25ZR21 rear) that they look like oil drums on their sides.
The best angle? The rear - straight on. Those headlights.
Wait, no, it’s from above - so you can see the V8 through the glass hatch.
Or it could be front-on looking like a giant shovel..
OK, there are no bad angles..
The Corvette Z06 is long at 4734mm end-to-end, broad at 2024mm wide and its height is a both a sitting-on-the-road-low and numerically pleasing 1234mm.
The plainness of the cabin might be a let down to some people after all the exterior wildness. Ferraris and Lambourghis offer extravagant and exotic interiors, but the Corvette’s innards are almost completely void of flare.
The media screen is small (8.0 inches), switches and controls for windows and air vents are basic, and the huge dividing ‘wall’ between the pilot and passenger might be a bit much for some.
That ‘wall’ is dotted with buttons and while it may look very 'fighter jet cockpit', they’re just climate control switches. Sitting in the passenger seat is a lonely place with no screen visibility nor easy access to controls - I'd actually call this out as a bit of a fail compared to the interiors from Porsche, Audi and Lamborghini with their screen-filled cabins offering co-pilots something to do.
Yes, it feels a bit premium with the Nappa leather and the sports seats, but it could feel more special.
All of this plainness, however, is saved from boredom by the glass window behind the seats allowing you to peer into the engine bay at the V8 like at a reptile enclosure at the zoo.
While there are some big changes underneath, on the surface the design tweaks are quite subtle.
There are some tweaks to the front grille, headlights, lower bumper and air intakes, but overall the look isn’t dramatically different. The more noticeable styling change is between the S and RS models, with the latter looking more sporty and dynamic thanks to a unique lower bumper design and the larger alloy wheels, which have a sportier look.
The biggest design changes are arguably the introduction of the switchable transparency roof on the RS and the option to use matt carbon camouflage.
The former is another shared element between the RS e-tron GT and Taycan, and it uses a special glass that can switch between being clear or opaque depending on whether you put a current through it. Cleverly, Audi is offering the option to have individual sections alternate between the two states, so you can customise it to your preference.
As for the grandly named matte carbon camouflage, it wasn’t highlighted in Audi’s presentation, but it’s the same material the Lamborghini developed over a decade ago and calls ‘forged carbon’ instead.
Unlike traditional carbon-fibre, which is made from injecting resin into sheets of fabric-like carbon fibre weave, forged composite uses a malleable paste of carbon sheets and resin. This technique is quicker to make and easier to shape into complex pieces, but lacks the visual impact of conventional carbon-fibre.
The biggest design change internally is the new steering wheel, which is a not-quote-squared-off rim that feels nice in your hand without being too thick. The RS models feature two new large red buttons - ‘RS’ and ‘Boost’ - which allow you to select the drive modes and activate the short boost function, respectively.
Supercars don’t tend to be built with practicality as a priority but this two-door, two-seat beastie is spacious enough even for me at 185cm tall with plenty of room in the footwell and loads of elbow-, knee-, and headroom.
Cabin storage is limited to a glove box, door pockets, two cupholders, and a wireless phone charger on the bulkhead behind the seats.
As you can see from the images there’s a boot at the rear which will fit smaller bags and a small boot in the front.
I did the school run in the Corvette a few times (I know, lucky kid) and I can tell you a bass guitar in its case and a school bag, plus my own large handbag make for a cramped cabin. A Kia Carnival the Corvette ain’t, but it’s not trying to be one and compared to its rivals it does well for practicality.
Practicality is an important consolidation for the e-tron GT, it may have replaced the two-seater R8 as Audi’s definitive performance hero, but it’s a four-door sedan so it needs to be more family friendly. It’s especially relevant for Audi, as the brand has a history of brilliantly combining family needs with fast cars, namely its iconic wagons, the RS4 and RS6 Avants.
Audi also has a strong reputation for some of the best interior design in the industry, and the e-tron GT is arguably amongst its best work (at least in this reviewer’s opinion). It looks modern and stylish without leaning too far towards being different simply because it’s an electric car.
The new steering wheel fits the new design well, framing the digital driver’s display nicely. The display itself has a new RS-specific display for the higher-end models.
There’s a central infotainment touchscreen, but underneath this particular Audi skips the climate control touchscreen in favour of a digital readout and physical switchgear; a welcome relief for some, no doubt.
As for the seats, all three trim levels get the same style of sports seat trimmed in Nappa leather with a honeycomb stitch pattern. There are different finishes, both black and red leather, and some with contrasting stitching available through the optional design package. The RS performance package gets a unique ‘serpentine green’ stitching to stand out.
Small item storage in the front is adequate but not generous, which does make the e-tron GT feel more like a sports car at least, even if it doesn’t help practicality.
As for the rear, space is surprisingly good given the external dimensions and the nature of it being a low-roof sedan (rather than an SUV) with batteries underneath the floor. That’s largely because Audi has split the battery pack to allow for extra room in the rear for passengers’ feet, combating a common problem with electric sedans.
Headroom is adequate, and will be tight for anyone much taller than 180cm, but it will do the job of transporting the family in relative comfort. It is, by no means, the most spacious or family friendly model in the Audi range, but it does play its role as both a performance car and roomy sedan.
The boot is measured at 405 litres in the S but shrinks to 350L in the RS models, but both have the same 77L space under the bonnet, so space is (again) reasonable without being generous.
Almost never does a car with a list price of almost $400K get full marks, but here we are and I’ll tell you why. The Corvette Z06 in its standard form lists for $336,000 and this is outstanding value compared to its supercar rivals such as the Ferrari F8 Tributo for $484,888, or a McLaren 750S for $585,800 or even an entry-grade Lamborghini Huracan, the EVO, for $383,187.
Australia gets the top 3LZ trim, with the local standard features list for the Corvette Z06 including Nappa leather upholstery, GT2 bucket seats, a 12-inch digital instrument display, a 14-speaker Bose sound system, red seat belts, wireless phone charging, carbon-fibre and suede microfibre trimmed steering wheel, a media system with sat-nav plus wireless Apple CarsPlay and Android Auto, power seats, heated steering wheel, dual-zone climate control, heated and ventilated seats and a head-up display.
Our test car was fitted with plenty of options including the Z07 Performance Package that brings carbon-fibre everything. We’re talking the enormous carbon-fibre rear wing and aero kit with side skirts and a front splitter with dive planes –and there are the carbon-fibre wheels (20-inch at the front and 21-inch at the rear).
The Z07 package also brings a more hardcore suspension tune and carbon ceramic brakes for ridiculously good stopping power.
The Z06 has the most powerful V8 engine in the Corvette range, too, and we'll get to that soon.
The 2025 range begins at $209,900 for the S e-tron GT, steps up to $264,900 for the RS e-tron GT and hits $309,900 for the new RS e-tron GT Performance (all prices exclude on-road costs).
While there is more power and equipment, that’s still a significant leap in price, with the previous e-tron GT starting at $181,784 ($28,116 cheaper) and the RS e-tron GT priced from $250,484 ($14,416 cheaper).
This pushes the Audi close to its most direct rival, the Porsche Taycan. Despite what the brands try to say publicly, the reality is these two are very closely related mechanically. Porsche now has two models cheaper than the S e-tron GT (the $174,500 Taycan RWD and $184,500 Taycan 4), while the Taycan 4S is priced just above it at $215,700.
Porsche’s rival to the RS e-tron GT is the $260,300 Taycan GTS, while it has the $306,900 Taycan Turbo to challenge the new RS e-tron GT Performance - plus the Turbo S and Turbo GT above it for those craving more power.
While the Audi isn’t bad value, it isn’t surprising that people in the market for an electric performance car from Germany are leaning towards the Taycan instead of the e-tron GT given the pricing structure.
In terms of specification difference between the three variants, the S e-tron gets 20-inch alloy wheels, adaptive air suspension, all-wheel steering, HD Matrix LED headlights with Audi laser lights, and a panoramic fixed glass roof.
Moving up to the RS e-tron GT adds unique 21-inch wheel design, a panoramic glass sunroof with a new switchable transparency, performance brakes with a carbide coating, and an RS-specific instrument cluster design.
The RS e-tron GT Performance crowns the range with its own 21-inch alloy wheels, active suspension and a specific RS Performance exterior electric sound system as standard.
There are a range of option packages too for all three models, which bundle extras together. The Sensory package ($6000) and Design package ($3800) are available for the S, the RS can be had with the Gloss carbon exterior styling package ($6000) and RS design package ($4500), and the new RS Performance has the matte carbon camouflage exterior styling package ($10,000) and a unique version of the RS performance design package ($4500).
The 5.5-litre naturally aspirated V8 in the Z06 makes 475kW and 595Nm. That’s a lot more power than the Corvette Stingray’s V8, which produces 369kW. The GT3 racecar version of the Z06 uses a derived version of the 5.5-litre V8, and actually it shares 70 per cent of the engineering components.
Revving to a high 8600rpm the Z06’s V8 lets out a high-pitched scream when pushed hard, much like a Ferrari because like many Ferraris the Z06 has a flatplane crank V8 - actually it’s one of the largest flatplane V8s to go into a production car.
Corvettes are now mid-engined cars and the Z06 has an eight-speed dual-clutch transmission that changes gears quicker than I can blink, sending all that mumbo straight to the rear wheels.
Acceleration comes hard, fast and loud with the Z06 able to boot itself from 0-100km/h in 2.9 seconds. That beautifully linear acceleration with no turbos will pull you all the way towards its top speed of 313km/h.
The key number for the new model is 680kW - that’s what the new RS e-tron GT Performance produces from its dual electric motors. That makes it the most powerful production car Audi has ever offered, which is quite an achievement when you look back at some of the cars this brand has built over the years.
That power upgrade is an extra 205kW over the pre-facelifted RS e-tron GT, and comes with a whopping 1027Nm of torque.
The RS e-tron GT has been upgraded too, now making 630kW/865Nm, a 155kW improvement on the old model. Which is a good thing, because the new S e-tron GT has even more power than the original RS, underlining just how much Audi has focused on power for this mid-life enhancement. The new S packs a 500kW/717Nm punch, compared to the 475kW/830Nm the previous RS offered.
As with practicality, fuel efficiency isn’t the Corvette’s priority and after driving it daily for a week in the suburbs, city and a few dashes out to more open country roads the Z06 was using an average of 23.8L/100km, according to the trip computer.
Luckily the fuel tank is pretty big at 70 litres and with an official combined fuel consumption of just under 16L/100km you have a range of 438km… in theory.
Another one of the significant unseen changes for this update is the battery. Audi has overall the battery for this latest e-tron GT, so it now has higher energy density (168.3Wh/kg), more size (105kWh v 97kWh), faster charging (10-80 per cent in 18 minutes) and reduced weight (down 9kg).
Despite all the extra power, driving ranges for the three models are still all beyond 500km. The S e-tron GT has a claimed range of 558km, the RS e-tron GT can manage up to 522km and RS e-tron GT Performance can run 528km on a single charge, according to Audi.
As for the charging itself, Audi claims it now takes just 18 minutes to get from 10 to 80 per cent using an ultra-fast DC charger.
What the Corvette Z06 is like to drive really depends where you drive it. Our suburb has a ridiculous number of speed humps, which are like the Corvette Z06’s Kryptonite thanks to its very limited ground clearance and a carbon front splitter that almost skims the road at the best of times.
This made the Z06 one of the slowest fast cars I’ve ever piloted. My son would beg me to drive him to school in it, but the journey would take twice as long as we slowly eased over each hump while holding our breath. A lift system does raise the front of the vehicle but even then, don't breathe out.
The width and poor visibility made inching down narrow streets of parked cars a stressful exercise, too.
The Corvette Z06 is almost too much of a racecar to live with and then you let it free on an open country road and its purpose is clear - it runs like you wouldn’t believe and screams in delight all the way, while clamping itself to the road with sticky tyres, perfectly set up suspension and proper downforce.
Steering feels mainlined though to your nervous system, the pedals under your feel like your actual feet, and it all feels like a dream until you wake up again when you reach the city limits and round abouts, and traffic and yes, speed humps.
The Corvette Z06 clearly is a car that needs to be joined by other cars in your driveway, ones that don’t even notice speed humps.
Befitting its role as Audi’s performance hero, the new range drives with a level of speed and precision you would expect from such a car.
Even the new S e-tron GT has a level of acceleration that not every sports car could keep up with (the official 0-100km/h claim is 3.4 seconds), which would be impressive on its own but is a standout when you consider this is a four-door sedan.
It also helps that the adaptive air suspension and all-wheel steering (which can help both low speed manoeuvring and high speed changes of direction) make for an incredibly responsive and agile handling vehicle.
And then you drive the RS e-tron GT Performance and the driving experience is a step up again with its 2.5s triple-digit sprint time. That’s largely because of the new active suspension system it uses, which features a hi-tech array of cameras, radars and sensors to ‘read’ the road ahead of it and adjust the ride accordingly.
The result is arguably one of the best riding, most comfortable electric performance cars on sale today. Typically the need to control so much weight, from the batteries, means the ride is often too firm. But with the active suspension, Audi has somehow managed to make the ride both compliant (on 21-inch wheels) but also very well controlled, which allows you to really drive with precision even at speed.
But it’s not just the suspension, as mentioned earlier, the RS models also get a new ‘Boost’ button on the steering wheel that offers an extra 70kW of power for 10 seconds. Along with the surge of extra performance there’s a large countdown timer on the digital dashboard when you press it to really give you a sense of urgency and speed.
Thankfully, with so much power the e-tron GT range has plenty of stopping power. The S comes equipped with steel brakes, which do a fine job. But for the faster RS models, you get a carbide coated rotor and you can option ceramic brakes for more resilient stopping power.
Along with four airbags, the Corvette Z06 has AEB, forward collision alert, lane-keeping assistance, rear cross-traffic alert, blind-spot monitoring, auto high beam headlights and adaptive cruise control.
An ANCAP safety rating doesn't exist for any member of the Corvette and will likely never due to low volume.
Audi has equipped the e-tron GT trio with a respectable level of safety features, including adaptive cruise control with stop and go functionality, park assist plus, front and rear autonomous emergency braking, active lane assist, side assist with exit warning, collision avoidance assist and a 360-degree camera system for parking assistance.
Given its low sales volume, ANCAP has not crash tested the e-tron GT (or the structurally similar Taycan), so there is no score. But overall its level of equipment and Audi’s reputation and experience means we have no safety concerns over this particular model.
GMSV covers the Corvette with a three-year/100,000km warranty which is short by current standards where carmakers typically offer a duration of five years/unlimited kilometres.
One of the appealing sides to the Corvette is that it’s made by a down-to-Earth American car company and a longer warranty offering peace of mind would seem more appropriate.
Service intervals are every 12 months or 12,000km, with capped-price servicing sadly unavailable.
Audi offers its standard five-year/unlimited kilometre warranty for the three e-tron GT variants, but the battery gets a specific eight year/160,000km warranty. The five years of coverage is fairly standard for the luxury car segment, but short of the increasingly common seven-year warranties for mainstream brands.
As for the servicing, that’s included in the cost of the car, with Audi covering the first six years of maintenance for no additional charge. It helps that service intervals, without a complicated and oily engine, are stretched to two years or 30,000km.
