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…
Following the money comes pretty naturally to carmakers. It’s what happens when the product planning department smells a new direction on the breeze and then handballs that to the design and engineering folks who turn a perceived market trend into a showroom reality. And when everybody gets it right, you have a new default product. And everybody else has to keep up. Some even have to catch up.
We’ve seen it plenty of times before, too. Think about those early 1980s days when the default small car went from a sedan to the five-door hatchback. Didn’t that catch on? You might also remember more recently when a family car had to be a four-wheel drive. And what about the dual-cab ute revolution of the last 15 years?
The other strident market segment right now is the SUV, of course. And within that, most recently has been the march to electrification, starting with conventional hybrid technology and now progressing to the new must-have, a plug-in hybrid platform.
The fact is, if you’re a Chinese carmaker intending to sell on a world stage, you can’t ignore the plug-in SUV in any of its various sizes and marketing segments. There’s a good basis for this, too. Plug-in hybrids just make good sense. They offer the urban running-cost advantages of any hybrid, the option of zero tailpipe emissions, all-electric running over a normal commuting distance and – crucial for a big country like this one – they’ll keep motoring along for as long as the owner puts petrol in them.
Okay, so they can be heavy with all that tech on board, and there’s no denying that two power sources (petrol and electric) make for a more complex machine, but the advantages outweigh the downsides for many buyers.
The other graph you can plot with great certainty is that new tech will get cheaper as the industry moves forward. Which is exactly where BYD finds itself right now by being able to offer a plug-in hybrid variant of its Sealion 5 mid-sized SUV at a price that will have much of the opposition running scared. But how scared should the others be?
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.
Cars that don’t always appeal to enthusiast buyers are often seen by manufacturers as a way of not bothering with the dynamics. Good enough is, apparently, good enough. Thankfully, BYD hasn’t taken that path here and the local suspension tweaks have turned what could have been a me-too product into a bit of a dynamic class leader. And even if buyers can’t verbalise the benefits of that, they will still be subliminally enjoying them with every kilometre.
The other stand-out feature is the price-tag which represents an awful lot of car for the money. And, in such a price-sensitive market as this one, that will get the BYD over the line for a lot of families. That it also offers a vastly better driving experience simply makes the value equation – and the purchasing proposition – even stronger.
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.
The interior of the Sealion 5 feels pretty well-made and there are soft-touch surfaces on most of the touch-points. The steering wheel, too, is thick and chunky and nice to hang on to. But there’s a lot going on in terms of different colours, textures and surfaces, and it can all look a bit busy, despite the high-tech boardroom overall flavour. It’s also worth mentioning the trim material is synthetic but does a great job of looking and feeling like real leather.
Externally, there’s not a lot to grab the eye. Sure, it’s not an unpleasant looking vehicle, but neither does it stand out from the mid-size SUV pack. At least BYD decided against those cheap-looking plastic tack-ons on each wheel-arch.
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.
Here’s the other big shock relative to the price-tag of the Sealion 5: This is not a small car. Based on the price, you might have been thinking the vehicle would be a compact SUV. And you’d have been wrong. This is a proper mid-sized SUV with room for five and luggage and an overall length of 4.7 metres and change. And to put that into some kind of perspective, that’s just 30mm shorter than the Sealion 6 which costs about $9000 more at its starting point.
The wheelbase is long, too, and the 2712mm between the axles helps make the interior even more spacious. That means there’s lots of stretching room in the front, but also that a grown adult can comfortably sit in the back seat behind another grown adult at the wheel and still have enough room in every direction. The window sills are commendably low in the rear seat, too, ensuring even littlies can see out.
The biggest problem in the back is that the seat cushion is a bit flat, but, like the front chairs, it’s still pretty plush.
With all five seats in place, the Sealion 5 boasts 463 litres of luggage space and the cargo area is well done with storage pockets at each side, a light and an under-floor tray designed to transport charging cables and a tyre repair kit. Yep, that’s right, there’s no spare tyre of any sort here. No surprise, really.
Fold the rear seat down and you’re suddenly looking at 1410 litres of cargo space and your SUV is now a panel van.
As well as the dual-zone climate control, the Sealion 5 also offers a single USB -C and a USB-A charging port in the front and rear compartments.
The Sealion 5 also offers a V2L (Vehicle to Load) function, meaning it can power camping or on-site work equipment and even act as your home’s battery.
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 plug-in hybrid in question is the BYD Sealion 5. It has a claimed EV-only range of better than 100km, relatively quick charging, a decent sized battery, adequate performance, enough interior space for a family, good safety and lots of equipment. Oh, and it costs just $33,990, before on-road costs, in its entry-level Essential form. Incoming!
Equipment-wise, that sub-34K sticker gets you a 10.1-inch central info-screen, an 8.8-inch driver display, digital radio, a six-speaker stereo, wireless connectivity for Android Auto and Apple CarPlay and dual-zone climate control.
Throw another four grand on the table and you move up to the Premium version which adds plenty of kit for the $37,990 ask. That includes a panoramic sunroof, automatic tailgate, roof rails, heated and electrically folding mirrors, one-touch power windows, a six-way powered drivers seat and four-way powered co-pilot’s chair, a heated and ventilated driver’s seat and wireless charging.
The step up from Essential to Premium also includes a battery upgrade, and we’ll cover that off in the Under the Bonnet section below.
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.
Both variants of the Sealion 5 have the same driveline – mostly. They each use a 1.5-litre petrol engine teamed with a single electric motor, both driving the front wheels. Unlike the bigger Sealions, there’s no all-wheel drive version. Power peaks at 156kW and torque at 300Nm.
Why a non-turbocharged engine? BYD tells us the non-turbo engine helps keep cost out of the vehicle and, since the engine really only runs to power the electric motor and charge the batteries, it does so at a relatively constant engine speed, negating the need for a wide spread of petrol power.
The only major difference is that the Essential version has a 12.9kWh battery-pack, while the Premium gets a bigger, 18.3kWh pack for longer range, but precisely the same output and, therefore, performance.
A single-speed transmission is part of the BYD driveline package, also made possible by the fact that the vast majority of the driving of wheels is done by the electric motor.
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.
The Premium’s bigger battery claims to up the official NEDC range from the Essential’s 71km to 100km. BYD reckons with the 52-litre fuel tank brimmed and the car operating at its claimed 1.2 litres per 100km efficiency, the range of either version is just on 1000km. In the real world, that’s likely to be closer to 800km (especially with some highway running thrown in) but it’s still one heck of a solution to range anxiety.
There’s no DC charging function for the Sealion 5, so forget about commercial fast chargers. But on a 3.3kW AC power outlet, the maker claims the Essential can reach full charge in under four hours, while the Premium’s bigger battery will take under six hours to fully charge. A Type 1 charge cable is included.
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.
You don’t have to drive very far to realise that the local input into the Sealion 5’s suspension and steering have been worth the effort. BYD Australia has a local engineering team on call these days, and it shows here.
Actually, the steering is not the highlight; it has some weight but not a whole lot of feel, or, indeed, feedback for the driver. The ride and handling combination is what stars. Obviously well-damped, the suspension allows for a ride that is both complaint and quiet, without causing the car to wallow around like some jacked-up designs can with their higher centre of gravity.
In fact, the BYD is athletic to the point where keener drivers will find it an entertaining drive; hardly something that can be said for the majority of medium SUVs.
Performance is strong without being overwhelming and even though the Sealion 5 has that signature electric-drive feeling of effortlessness, the accelerator pedal has been calibrated to avoid the neck-snapping surge of grunt off the line. As such, it emerges with a fairly flat acceleration curve, and no hint that the petrol motor is cutting in or out.
Until, that is, you bury the throttle all the way at which point the petrol engine takes a few second to join in. And when it does, it’s pretty vocal – shrill, almost – as it catches up with the rest of the car and starts directly driving the wheels. To be fair, though, this is not going to be a common occurrence in everyday life thanks to the flexibility of the petrol-electric system for 99 per cent of circumstances.
On the move, the cabin is perhaps most notable for its soft, plush seats that are a nice change from the church pews of some manufacturers. And although the driving position is about right, taller drivers might prefer a steering column that extends out another few millimetres.
The driver display screen is another source of annoyance. It’s pretty small and contains lots and lots of information, to the point where the typeface is too small to be read on the run by anybody who relies on reading glasses.
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.
Passive safety in the Sealion 5 starts with no fewer than seven airbags including full-length side-curtain bags.
There’s also a front-centre airbag, something we’d like to see in more cars, particularly at this price-point. Child restraint points in the rear seat are the ISOFIX type.
The BYD gets pretty much the full suite of driver aids, including autonomous emergency braking, blind-spot monitoring, rear-cross traffic alert with active assistance, stability control, active cruise-control, traffic-sign recognition, front and rear collision warning and tyre pressure monitoring.
The Sealion 5 also incorporates a driver-attention monitor which seems better calibrated than some earlier efforts from some of the Chinese carmakers. Also improved in calibration terms is the lane-keeping assistance which is still too violent for our tastes, but more subtle than some of the competition’s systems. But while the savagery of this system has been toned down, it appears to have been at the expense of sensitivity and, time and time again, the cameras missed road markings that were faded or dirty.
The major safety benefit in paying more for the Premium variant is the addition of front parking sensors and a 360-degree camera instead of the Essential’s simple reversing camera.
The Sealion 5 has not been ANCAP tested as yet, although BYD says this is largely down to ANCAP’s scheduling rather than any hesitance on BYD’s part.
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.
Like other BYDs, the Sealion 5 comes with a six-year/150,000km warranty. Some of the competition have unlimited kilometre warranties, but to be honest, 150,000km in six years is going to be beyond the need and aspirations of most owners.
The EV battery is covered by an eight-year/160,000km warranty, and let’s not forget, BYD was a battery manufacturer before it started making whole cars. Certainly, the company is very bullish about the quality and safety of its 'Blade' battery technology, claiming it easily passes the technically-daunting 'nail-puncture' test.
BYD plans to have capped-price servicing for the Sealion 5, but no pricing announcements have been made yet.
Servicing also falls into line with other BYD models, so that means 12 months or 20,000km intervals.
