Driven: Corvette ZR-1

Can the fearsome 638bhp Corvette ZR-1 cut it with a gaggle of blue-blooded supercars?



What defines a supercar? Is it a certain level of power? How much does outright performance come into the equation? Does it have to be mid-engined, impractical and generally larger than life? And how important is the badge on the nose?

Whatever the answer is, I know it's a complicated one. I've just thumbed through my Concise Oxford English Dictionary for a spot of help and come up with the thoroughly woolly description of a supercar as "a high-performance sports car".

What I can tell you, however, is that the C6 Corvette ZR-1 is most definitely and most assuredly a full-on supercar. Supercar status is not something that has been bestowed on the Corvette before now, but it was surely only a matter of time (and, possibly, horsepower).

Think about it. The muscle car tendencies of the Corvette already endow it with certain supercar attributes. There's that sharp-looking body, not inconsiderable girth and a variety of large-capacity V8s. Oh, and it's also got the added impracticality of left-hand drive. Very supercar.


The Corvette also has further exotic credentials courtesy of an aluminium frame, composite body panels and double wishbone suspension all round. To this the ZR-1 then adds a healthy dose of carbonfibre and a supercharged 6.2-litre LS9 V8 with 638bhp and 604lb, bringing a 205mph top speed and a 0-62mph sprint of just 3.6 seconds, thus ticking a few more boxes on the supercar checklist.

What complicates matters with the 'Vette is that it apparently fails a few crucial supercar tests. The engine, being in front of the driver, is in the wrong place for starters. Now, this isn't a red-card offence for a supercar, but there are only a handful of models out there that could even apply for entry to such an exclusive club. The ZR-1 can try to ape its mid-engined rivals all it likes with the Perspex window onto the engine cover but, rather than looking mid-engined, it just looks a little crass. It's also cheap by supercar standards. £106k? Hah, pittance (look at the price of a Veyron or an F40). Finally, it's not German, British or Italian, which puts the Yank on rather a back foot in such elitist, old-money company.


To clear the matter up for sure, we decided to join the convoy of A-list supercars on the run from London to the recent Wilton House Supercar Show near Salisbury. Could the ZR-1 stand comparison with F40s, Veyrons, McLaren F1s, Diablos and Enzos?

The Corvette scores a partial victory immediately as we wait to set off. Despite some seriously exalted company the Corvette is holding its own and drawing plenty of attention. Even if that's only because of its sheer rarity, that has to be chalked up as a bit of a victory.

As we head out of London and onto more open roads the task facing the Corvette is apparent; every time the M3 crests a brow there before it is a line - as far as the eye can see - of gobsmackingly exotic metal. The 'Vette is not cowed, though (if you'll excuse the unintended pun); that 638bhp V8 lump means the humble Corvette can stay with anything this side of a Veyron.


The point is proven in emphatic style as we come out of a section of roadworks tucked up on the inside lane beside a brace of Lamborghinis; a Diablo SV, a Gallardo and a Murcielago. Just before the derestriction sign, the Lambos slow right down, before booting it as they pass back into normal motorway space. I'm about half a second slower than them to get my foot on the gas, but the ZR-1 more than makes up for my sluggishness. Through third, fourth and fifth, the full-chat acceleration has me fully pinned back in my seat and, by the time we (very) briefly touch speeds that we really shouldn't be doing, I have damn nearly undertaken the hard-charging Lamborghinis. The ZR-1 really is that quick.

Before we reach Wilton House we make a detour via Gurston Down hill climb course. It represents a great opportunity to put the ZR-1 through its dynamic paces in something other than a straight line. This is the only hill climb course in the country that starts downhill and, being a hill climb course, it's narrow and tight, and a seriously tough test for a car as big, wide and powerful as the ZR-1.

I tackle the hill carefully, but for such a big car the ZR-1 copes with the narrow confines of Gurston with aplomb. You can't let its copious amounts of power of the reins much, but the brakes are strong and there's grip to spare. It's even surprisingly agile around Gurston's tight hairpins. Switching the traction control off is a game only for the strong-stomached, however; with all that power and so little weight over the rear wheels, a smoky exit from slow corners is but an accidental twitch of the right foot away.

So has the ZR-1 proved its supercar mettle? It's certainly as fast, capable and exotic as the most super of supercars, but speed and power are just some of the numbers in supercar maths. Corvette ZR-1 = supercar? We'll leave you to balance that particular equation.

I think the vette is a true supercar no doubt has the speed and has had rave reviews of everyone that drove it. I also think it looks rather nice as well and think it does unlike some people look like a 100k car to me. The only problem looking is that interior just looks a bland mess to me and is a real disappointment also the seats look more like arm chairs and I would have though with a car of that performance you would want something which could hold you tight in the bends. Apart from that though I think it seems like a great car and if I had that sort of money I would certainly consider one even in the UK.

That traction control button is fantastic biggrin

ETA: the interior is rather Japanese in its execution, although the pictures aren't the most flattering I've seen.

Excusing the picture sizes and awful interior colour, this highlights more of the material contrasts, there's a lot of leather, its mainly those centre fans that bother me when staring at the picture.

They remind me of Porsche seats...

An impressive machine, but I found myself drawn to the words 'leaf spring' in the specifications - how do those fancy versions work then?

Like this................

This is the rear of a mid 70's Corvette IRS. The leaf spring (singular) is mounted transversely and clamped in the middle. Each end controls the IRS independently of the other side.
The later models have a composite spring mounted in the same way and are a bit more sophisticated. Can't find a good pic though.

Don't get too hung up on the Clarkson/TG "It's got leaf springs" vibe. They try to make it sound like an Ox cart, which it isn't.

Fantastic cars. I don't think you can be a true petrolhead without having some fondness for the Corvette. Whether its the olde style originals, the hairy-chested 70's ones or the 1980's "Face-from-the A-Team" ones, sure they might not be all that great to drive but they have a little bit of I don't know, "je ne sais quoi" about them. Bit of character and some degree of either absurdidty or elegance about them - which should be another defining feature of a supercar.

The C6 though, apart from being a looker and characterful, I think is a good proper car. OK, it might not be quite so sharp as the equivalent Porsche or Ferrari, but by any reasonable standards its pretty good. The Z and ZR are proper mentalist. I likes!

Like Euroboy above, I rented one in California last year and fell in love with it. I had preconceptions that it wouldn't be a razor-sharp drive, but I was wrong. I have owned a succession of Elise variants, and I was taken by the C6's combination of handling, power, comfort and value (and 33mpg on the motorway!)

I am seriously tempted with a Z06 when I grow too wide for my Lotus.

When the C5-R raced the Fezza 550's at le Man it was the Fezza that was quickest in a straight line & the Vette that could handle the corners!

"the Perspex window onto the engine cover ....... just looks a little crass."

Damn right. IMO the performance can and does speak for itself.

Lotus Evora has an identical problem at the back. Little plastic engine cover proudly on display under its own little window. Nuts.

True supercars may be expensive and blue-blooded but Corvette is undoubtedly THE blue-collar supercar.

Nice story but unbeleivable amounts of crap concerning "supercars" rolleyes



BTW - exactly where are the engines in these:

The author of the article read Evo recently.

There are a few original journos around, the rest just repeat parrot-fashion what the good ones write. Look how many quote Clarkson while trying to sound superior.

What a load of b0llox. I'm not even going to shame the author by listing all the front engined supercars that have been and gone. Corvettes where supercars in the 80's when they did 180mph.

Absolutely love the car but that interior is simply not good enough. Look at the traction control button. It looks cheap, very plasticy and the texture has been flatted down due to the heat created when they put on the vette with tyre marks. the exterior and performance fgures would make up for this but since you will only ever be driving it from the inside this lets it down.

Like a school report. Must try harder.

The point is that I don't really think the Corvette, or any of the cars pictured above, are supercars. They may well be super cars, but not supercars. There's no hard and fast rule, but I tend to think a 'supercar' should have a mid-engine. Doesn't really matter in my opinion, its still one of my favourite cars whatever you want to call it.

No offense mate but that's a pretty dumb take on it.

You want Ferrari 599 performance on a budget = Zr1 fulfills

You want the performance and all the expensive extra trimmings you pay the friggin price and buy a Ferrari 599.

If you don't want the performance and only want the interior and don't want to pay 599 prices then look elsewhere like a base model 911.

You can't have it ALL for nothing FFS.

The only thing with this view, is what before the Miura would you consider a supercar? And what exacly are are all these other cars with the engines in different places; Ferrari 599, Aston Vanquish, McLaren SLR and so on.

Sure, a lovely interior would be good but I can't say it'd put me off. Apart from the fact that the bits which make this car great are in its chassis and especially the engine, it's hardly minging is it? I mean, OK, it's not hugely innovative or pretty but it's OK, the materials are OK and it works.
