Chevrolet Corvette vs Chevrolet Silverado

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.

This is a serious truck with load-carrying and towing capabilities far beyond Australia’s ubiquitous Ranger/HiLux-sized one-tonne utes. However, those vehicles thrive in urban use due to their relatively compact dimensions so, in that context, this pick-up is simply too large to be a practical alternative. However, if you have more specialised work and recreational requirements, like GCMs as high as 12 tonnes with spacious comfort for a crew of five, this big American would be tough to top.

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.

MY24 brings a freshened front-end appearance with new fascia, headlights, body-coloured bumpers and grille garnish, black body highlights and more.

With a traditional ladder-frame truck chassis and sprawling 4036mm wheelbase, this behemoth measures almost 6.4 metres in length (6387mm) and more than 2.2 metres in width (2263mm).

It also stands more than 2.0 metres tall (2039mm) and has a vast 16.1-metre turning circle. So, multi-storey car parks, drive-thru takeaways etc are best avoided. And domestic driveways (if wide and long enough to accommodate it) may suffer under its weight over time.

It rides on 20-inch high-gloss black alloys with LT275/65 R20 Goodyear Wrangler all-terrain tyres and carries a full-size spare.

New Z71 off-road suspension includes skid plates and Rancho twin-tube dampers, offering 251mm of ground clearance and 28.5 degrees approach/19 degrees ramp breakover/23.6 degrees departure angles.

However, its 4x4 capabilities would be better suited to accessing rugged worksites, pulling a large caravan out of a boggy campground or towing a large boat trailer up a slimy boat ramp, than hardcore bush-bashing on narrow tracks.

The Silverado’s extensive remanufacturing to RHD, performed on a dedicated production line in Melbourne, exudes OEM standards of fit and finish. The dashboard module is particularly impressive, in providing a mirror image of the LHD original in appearance and function.

The leather-appointed cabin is a highlight, offering palatial space and comfort for all. It features a tasteful blend of contrasting materials and surface treatments, including silver-grey woodgrain inserts on the doors, dash and centre console plus exposed stitching along seams and subtle splashes of chrome.

The entry pathway to the rear seat is expansive, thanks to wide-opening doors and a flat floor with no transmission hump to straddle. There’s executive-lounge rear head and legroom, even for tall people, combined with enough shoulder room to ensure a crew of five can travel in comfort.

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.

With its towering 3762kg kerb weight, the 2500 HD offers a choice of ADR load ratings (NB1 or NB2) which must be specified by the customer at the time of ordering (at no extra cost) to ensure the correct certification for vehicle registration.

The NB1 category allows up to 4500kg GVM/733kg payload, which can be driven by car licence holders. NB2 allows up to 5148kg GVM/1386kg of payload, but requires a truck licence. Our test vehicle is certified for the lower NB1 rating.

The 2500 HD is rated to tow up to 3500kg of braked trailer with a 50mm ball and up to 4500kg with a 70mm ball. These trailer weights are well within its capabilities, given that its GCM rating (how much it can legally carry and tow at the same time) is an eye-popping 12474kg.

Yep, that’s more than 12 tonnes, which allows for trailers weighing more than 4500kg using heavy-duty connections like pintle hooks, goosenecks/fifth-wheel turntables installed and certified by specialist aftermarket suppliers.

The enormous load tub offers almost 2.0 cubic metres of cargo volume and has large external steps front and rear for easier access. The load floor is 2089mm long, 1814mm wide and 533mm deep, with 1317mm between the rear wheel-housings allowing Aussie or Euro pallets to be carried.

It’s protected by a tough spray-on liner, plus there are 12 load-anchorage points, LED lighting, power tailgate and a camera to keep an eye on loads when driving. Our test vehicle was also fitted with adjustable and removable load-dividers, which are part of the GMSV accessories range.

Cabin storage for driver and front passenger includes two bottle/cupholders and a large bin in each door plus a single glove box. The centre console has a large open tray up front, two bottle/cupholders in the centre and an Esky-sized box at the back with padded lid that doubles as a plush elbow rest.

Rear seat passengers get a bottle/cupholder and bin in each door plus two more bottle/cupholders in the rear of the centre console and another two in the fold-down centre armrest. There are also large storage pockets on both front seat backrests and compartments cleverly hidden behind hinged upper backrest cushions.

The 60/40 split rear seat base can swing up and be stored vertically if more internal load space is required. This also provides access to the under-seat storage accessory fitted to our test vehicle. You’d seriously struggle to run out of cabin storage!

Our test vehicle is available only with GM’s 6.6-litre 'Duramax' turbo-diesel V8, 10-speed automatic transmission and dual-range 4x4 system for a list price of $163,000.

Our example has optional 'Slate Grey' prestige paint ($1250) plus GMSV accessories including a powered roller tonneau cover ($3970) and rear under-seat storage ($455) which adds more than $5600 to the price. So, with on-road costs, it's drive-away is more than $170K.

MY24 upgrades include styling, performance, towing and safety enhancements. There’s also a redesigned interior, with its most notable feature being upsized dash screens comprising a 12.3-inch configurable driver’s info display (paired with a colour head-up display) and larger 13.4-inch multimedia touchscreen. 

There’s also a premium Bose sound system, Apple/Android connectivity and wireless phone-charging, plus USB ports front and rear, dual-zone climate control, heated leather-rimmed steering wheel (with four-way adjustment), a power sunroof and power sliding rear window.

Leather-appointed seating offers 10-way driver and front passenger power adjustment, heated/ventilated front seats, heated rear seats, rear privacy glass, a power tailgate, tubular side-steps, 360-degree camera (and up to 14 different camera views), full LED lighting including fog lamps and DRLs plus heaps more. It’s what you might call fully-loaded - even without a load.

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 6.6-litre Duramax turbo-diesel V8, with driver-switchable exhaust brake, is tailored for heavy-hauling with an external engine oil cooler and functional bonnet scoop feeding fresh air to the engine’s intake system.

In the latest MY24 specification, it produces 350kW at 2800rpm and 1322Nm of torque at 1600rpm. That’s 18kW and 98Nm more than the previous model.

The refined 10-speed torque converter automatic with column-shifter is also fitted with an external oil cooler, while closer gear ratios and revised final-drive ratios for MY24 enhance all-round performance.

A dual-range transfer case offers a choice of four drive modes comprising 2WD, 4WD high-range, 4WD low-range and Auto (traction-sensing full-time 4WD). Also new is an automatic-locking rear differential.

Its armoury of advanced towing hardware and technology includes a 4500kg tow-bar with 12-pin wiring harness and integrated trailer brake controller.

Plus, there’s a rear-view camera with hitch guidance, automated trailer lighting test, in-vehicle trailering app with trailer profiles, trailer theft alert, trailer tyre pressure/temperature monitoring and lots more.

New MY24 features include adaptive cruise control which can be used when towing (detecting the additional weight behind the vehicle to automatically increase braking distances). Others are 'Trailer Side Blind Zone Alert' (TSBZA), which extends the blind zone area when towing, plus 'Gross Combination Mass Alert' (GCMA) which alerts if you exceed the GCM.

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 dash readout was claiming 17.5L/100km at the end of our 351km test, which comprised mostly city and suburban driving plus some highway running with a full payload.

Our own figure, calculated from fuel bowser and tripmeter readings, came in slightly lower at 16.8, which is decent economy for a vehicle weighing more than 3.7 tonnes unladen in ‘real world’ driving.

So, based on our figures, you could expect a realistic driving range of around 800km from its big 136-litre tank.

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.

Side-steps and large handles on the A- (and B-) pillars assist climbing aboard. It’s a very comfortable driving position, given the multiple seat and steering wheel adjustments along with plush elbow rests on both sides.

The large door mirrors, combined with numerous camera angles including the central rear view mirror's pin-sharp image, provide commanding all-around vision.

The steering is nicely weighted and surprisingly communicative for such a giant, providing good feel and response at all speeds.

The suspension tuning is supple enough to provide a smooth ride, yet retains enough firmness to minimise the ponderous feel inherent in vehicles of this size and weight.

Braking response is also reassuringly strong, without requiring huge pressure on the brake pedal to achieve it.

The 6.6-litre turbo-diesel V8 and 10-speed auto provide effortless performance. With maximum torque tapped at just 1600rpm, the engine is barely ticking over at city and suburban speeds.

And it requires less than 1500rpm to quietly maintain 110km/h on the highway, which combined with its low tyre and wind noise results in a supremely relaxed long-haul cruiser.

With its NB1 GVM rating, we loaded more than half a tonne into the load tub, which combined with our crew of two was just under its 733kg payload limit.

It simply didn’t notice the added weight, storming up our 13 per cent gradient, 2.0km-long set climb with acceleration unmatched by any loaded vehicle we’ve tested on this ascent.

Its engine-braking on the way down using the exhaust brake also set a new benchmark, never exceeding 50km/h and 2000rpm on overrun without once touching the brake pedal.

ANCAP star ratings are not applicable in this vehicle class, but it does come well equipped with six airbags including side-curtain protection for all outboard seating positions.

There’s also forward collision alert with low-speed AEB, lane departure warning, blind-spot monitoring (including when towing trailers), rear cross-traffic alert, front and rear parking assist, up to 14 camera views including 360 degrees ‘birds-eye’ and more.

There are three top tether points across the second row seat for securing baby capsules/child seats with ISOFIX anchors on the two outer positions.

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 Silverado is covered by a three year/100,000km warranty with three years roadside assist.

Scheduled servicing is every 12 months/12,000km, whichever occurs first, and there's no capped-price servicing. This ownership package falls short compared to rivals like Ford's RHD F-150.
