Chevrolet Corvette vs Kia EV9

What's the difference?

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.

The Kia EV9 GT-Line earns some serious family points with its practical and luxuriously appointed cabin. Each row enjoys ample amenities and space and you can’t discount the ability to fit five child seats!

That’s where similarities with its Carnival sibling end because the driving performance is too mixed for my liking. Some of its safety features don’t react well in real-world situations but if you’re looking for an electric car that will fit a big family, this ticks that box.

My son thinks the EV9 is really cool with the ambient lighting and two sun roofs. He also loves having his own climate control and sun-blinds, so he gives it a 10/10.

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.

To be frank, the EV9 resembles a Lego car on steroids, but it turns heads. I’ve had more looky-loos peeking into the windows this week than any other car I’ve driven.

Once you get over the (very) square shape, there are some awesome design aspects to be had.

Like the flagship exclusive Matrix LED headlights and 'Ocean Blue Matte' paintwork that feels velvet-like under your hands. The black 21-inch alloy wheels and their aerodynamic covers look futuristic and cool.

The pronounced nose looks wide-set because of the positioning of the tall headlights separated by a strangely blank panel in the middle.

In fact, the whole exterior incorporates a slew of blank panels which reinforce the square look.

The flush auto door handles, big windows and dark roof give some cool-kid cred. The digital side mirrors are not for everyone but as a driver, you get used to them. The tech looks as though it's come straight out of sci-fi movie!

The interior is downright plush with the premium-looking upholstery and customisable 64-colour ambient lighting.

The dashboard has floating panels which create a cool 3D effect and even the badge on the steering wheel is illuminated.

There is a plethora of soft touchpoints throughout and the black headliner helps make the cavernous cabin feel almost cosy.

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.

It’s large and you have ample space throughout the car. Even third rowers don’t miss out.

It feels quite van-like with the high seat positioning and extending centre console but you get a great view out of the massive windows.

The electrically-adjustable front seats are very comfortable but the mesh ergonomic headrests are a little too comfy!

The boxy steering wheel is nice to use but cut into my vision of the climate control screen from my driving position. I felt like I was looking around it a lot.

Individual storage is fantastic in all three rows. Up front you get a little pocket in the armrest and a huge shelf underneath the centre console.

The glove box is large, but curiously, has a small aperture. There are retractable cupholders in the centre console utility tray and drink bottle holders in each door.

The middle row has two drink bottle holders, four cupholders, two map pockets and a deep but narrow storage cubby at the back of the centre console.

Third rowers are not forgotten, either, with four cupholders and directional air vents to enjoy.

Amenities are great throughout the car and my son loves having the retractable sun-blinds and his own climate control in the middle row. It’s also an easy car to get in and out of, which we both enjoy!

The middle row's 60/40 split is a practical touch and they can be shifted manually or electrically with a one-touch button for access to the third row.

Speaking of which, there is an okay amount of room for my 168cm (5'6") height in the third row (if you push the middle row forward a smidge). And it doesn’t feel claustrophobic thanks to the wide windows.

If you have a pile of kids to shove in this car, you’ll be happy that this row also features two ISOFIX child seat mounts and two top tethers.

I wouldn’t want to be climbing into the third row to buckle in a kid, so reserve these seats for older kids.

The technology looks good but is simple to use which is always a good combination. There are plenty of charging options to choose from with each row getting two USB-C ports, while the front also enjoys a 12-volt socket and a wireless charging pad.

The touchscreen multimedia system is responsive and easy enough to use but the controls on this panel can be difficult to see and use. They’re not always responsive.

I like the satellite navigation and the way the head-up display pulls through the directions. There’s wired Apple CarPlay and Android Auto, too.

The digital instrument cluster is mildly customisable and easy to read. There is a little control panel on the driver’s door which houses the buttons for most of the added seat functions. But it’s hard to read as all the buttons are almost identical.

The boot is a good size when all seats are in use at 333L, which is plenty for my day-to-day errands, but pop the third row down and that jumps up to 828L.

Not as big as you might expect in a car of this size but that’s the compromise of going electric. The batteries have to go somewhere.

You do get a 52L frunk at the front, for cable storage. The loading space is level and you only get a tyre repair kit rather than a physical spare but it’s handy having the powered tailgate.

There are three variants for the EV9 and our test vehicle is the flagship GT-Line model that will cost you $121,000, before on road costs. That makes it the most expensive Kia to date, with the top-spec Carnival Platinum diesel only costing $67,580 (MSRP).

However, it’s nearest rival, the Mercedes EQS450 SUV, sits at $194,900 making the EV9 look downright cheap with the $73,900 price difference.

Yes, you could argue the badges would always offer a little price difference but Kia has made a true flagship model in the GT-Line because it is stupidly well-specified. It’s almost a case of what doesn’t it come with!

In terms of luxury appointments, occupants enjoy two sunroofs and two-toned synthetic leather upholstery. The electric front seats feature heat and ventilation functions, adjustable lumbar support and the driver gets a massage function.

The front seats have a relaxation mode, which I liken to the reclining seats in business class (someone send me on a trip to confirm!).

If you recline, add the sounds of nature feature and pop on the massage function, it’s like you’re in a day spa. Delightful.

The middle row outboard seats are also heated and ventilated which adds a lot of comfort and there’s a heated steering wheel, too.

Other standard equipment includes 21-inch alloy wheels, flush door handles, digital side mirrors, privacy tinted rear glass, pixel matrix LED headlights, 14-speaker Meridian premium sound and remote parking assist.

Practical features include a powered tailgate, extendable sun visors, retractable sun-blinds and three-zone climate control.

The technology is upmarket with dual 12.3-inch digital screens covering instrumentation and multimedia. There's also a 5.0-inch ‘quick-look’ climate control panel. A full tech run-down will come later.

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 EV9 GT-Line is a pure-electric AWD with dual motors, one located at each end of the car, producing a maximum power output of 283kW and 700Nm of torque. It has a lithium-ion battery with a big capacity of 99.8kWh.

Overall, the EV9 GT-Line is powerful and capable of sprinting from 0-100km/h in just 5.3 seconds. That’s impressive for such a heavy car with a 2500kg (braked) towing capacity.

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.

It's a hulk of a thing to have to move around and the motors perform brilliantly, but my energy cycle figure surprisingly came out at only 21.4kWh, after mostly open-road driving.

The official combined energy cycle is 22.8kWh, so that's a solid result.

The driving range is up to 505km, which takes the sting out of any range anxiety.

The EV9 features a Type 2 CCS port as well as an 11kW AC charger and you can get from 10 to 100 per cent in just over nine hours.

On a 50kW DC charger, you’d see that time drop to just 83 minutes to get from 10 to 80 per cent and it will shrink to 24-minutes on a 350kW charger.

A cool feature is the vehicle-to-load capability, so you can charge and/or power larger appliances on the go. Hello camping!

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.

Strangely for a large SUV, this car feels most at home in an urban environment. It’s in the city where it feels nimble and easy to manoeuvre. Zippy even, and you don’t notice it’s size.

But it’s a different story on the open road. 

At higher speeds there is a lot of movement in the body and thanks to its floaty suspension the amount of roll in corners starts to make it feel cumbersome.

It has the power to handle mountain driving or overtaking, but remains a bit unsure of itself in these situations.

The steering is responsive and concise, which makes for a nice driving experience in the city and navigating a car park.

The cabin gets very little noise thanks in part to sound-absorbing acoustic glass and foam in the tyres. It makes for a fairly pleasant journey overall.

As a passenger, though, I began to suffer motion sickness thanks to the digital side mirrors! Not an issue when I’m driving, but even my husband, who has an iron stomach, commented on how distracting they are.

It’s nice having a column shifter, as it helps open up the storage in the centre console but it can make pressing the push-start button a bit awkward.

The EV9 has a decent 12.4m turning circle and is relatively easy to park. The 360-degree view camera system is clear and I love having the front and rear parking sensors on this big boy.

But to access the front camera, you have to be in Drive. You can’t select it on the touchscreen, which is a pain when you’re manoeuvring into a tight space.

If you’re not confident, the EV9 also features an updated park itself feature which means you can park it remotely from your key fob. 

The EV9 has an extensive safety list and the blind-spot view monitor, which pops a video feed of your blind spot onto your dash, is a stand-out feature.

Standard safety items include blind-spot monitoring, lane departure alert, daytime running lights, forward collision warning, side collision warning, rear-cross collision warning, rear cross-traffic alert, intelligent seatbelt reminders, a 360-degree view camera system, as well as front and rear parking sensors.

There are other items but I need to call out their sensitivity issues.  

The driver attention monitor doesn’t always activate when you have sunglasses on and alerts you via multiple warning sounds and alerts on the instrument cluster.

The lane keeping aid is rather aggressive, which makes for a jerky on-road experience, and the adaptive cruise control with stop/go functionality isn’t nice to use.

Even on the shorter distance setting, it slows down way too fast when approaching a car in front.

Also, annoyingly, this model features all the warning chimes and alerts that are linked to the traffic sign recognition tech.

Go over the speed limit by one kay, chime. Enter a school zone, several chimes. If the speed sign changes, chime. If the traffic sign changes, you guessed it, CHIME.

Suffice it to say I don’t like this feature.

There's an option in the car set-up menu that turns off the warning sounds but keeps the important sign information. However, it's not permanent and has to be selected every time you turn on the car.

In better news, the Kia EV9 has just been awarded a maximum five-star ANCAP safety rating and features nine airbags which includes curtain airbags covering all three rows and side chest airbags for the second row.

Usually, you only see side chest airbags on the front row, so this is great! It also sports a front centre airbag to protect the front row from head clash injuries.

The EV9 has autonomous emergency braking with car, pedestrian and cyclist detection as well as junction turning assist.

It's operational from 10 to 80km/h but surprisingly, the car-to-car avoidance is only operational from 10 to 60km/h.

That upper speed figure usually sits closer to 160km/h. Unless there is a typo on ANCAPs website…

Families will rejoice that there is a total of four ISOFIX child seat mounts (two in the middle row and two in the third row) plus a total of five top-tether anchor points.

The car is large enough to accommodate five child seats and there’s plenty of room for front passengers when a 0-4 rearward facing child seat is installed on the middle row.  It’s pretty much a people mover at this point!

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.

The EV9 comes with a seven-year/unlimited km warranty, while its battery is covered for seven years, 160,000km. It’s normal to see an eight-year battery warranty term for EVs, though.

You can pre-purchase a three-, five-, or seven-year servicing plan, priced at $706, $1351 and $1997, respectively.

The seven-year schedule costs an average of $285 per service, which is good, but servicing intervals are more in line with a fuel-based car at every 12 months or 15,000km, whichever occurs first.
