Yeah, I know: a Bentley, an Ariel, an AMG Mercedes and a rebadged Holden arenât typical group test competitors, but then this isnât a typical group test. Itâs not even really a âtestâ in the traditional sense because surely there canât be a winner.
These cars all have V8s but this isnât a âgreatest V8s of all timeâ examination. Even a âgreatest V8s on saleâ comparison would be stretching it. There are some great V8s whose makers couldnât or wouldnât pitch them in.
So what, then, is the excuse for lining up this quartet on the north side of the A3 Hindhead Tunnel on a Tuesday morning as a prelude to this feature?
A serious, state-of-the-nation assessment of the V8 engineâs future? Or maybe itâs because we fancied V8 accompaniment on a run through the longest road tunnel in the UK on our way to the south coast.
The competitors
Our competitors go about the V8 thing rather differently. Bentley has made a turbocharged V8 for years, but only now has it tweaked this Audi-developed 4.0-litre two-turbo to put in the Bentley Continental GTC. Itâs a prime example of downsizing; notable as much for its 25.9mpg and the cylinder deactivation as it is for its 500bhp.
Joining it in the blown corner is the Mercedes-Benz E63 AMG. AMG has hitherto had its charismatic 6.2-litre naturally aspirated V8 but has also downsized. And added turbos.
Iâve a soft spot for AMG V8s, not only because of how they sound but also because in the factory, engine development dyno rigs are hooked up to generators. So when an AMG engine is on the test bed, itâs producing electricity for the rest of the factory. Thereâs every change the Affalterbach worker are boiling their kettles courtest of a wrung-out V8.
Weâre fans of the Arial Atom V8. We might have mentioned it in the past. It takes a certain mindset for a car company to decide a V8 is the right tool for powering a 550kg car. The Atom V8 makes 475bhp thanks to revving to the heavens. It has a flat-plane crank, too, so it doesnât sound like a traditional eight.
Vauxhall Maloo
Nothing in V8-land is quite so traditional as the engine installed in the Vauxhall Maloo. The Maloo might be an Australian wearing a British badge, but the engine powering it is pure V8 American tradition: the Chevy V8.
The latest Chevrolet LS3 motor displaces a heady 6.2 litres and can be considered the old stager here. Itâs the archetypal V8. Ask a petrolhead to do a verbal impression of a V8 sound and the chances are itâll sound like a Chevy. Lots of âblumsâ.

I own a 2005 Audi S4 Avant with the 4.2 V8 and every time I start her up the sound amazes me!!! LOVELY engine!!!!
Re: The V8 and the V great: V8 mega-test
Yes - I must admit my accusations of poor reliability were poetic license. More from the perspective that it should have been still-born, poor thing.
I had one once, and then fitted up a P76 V8 for my Land Rover. Terrier cam and a 4-barrel holley and that thing could boogie. The later Rover V8s had proper heads and actually worked OK. But they were never. Ever. Fuel efficient.
Re: The V8 and the V great: V8 mega-test
Yes, there is something to be said for a V10. F1 V10's were excellent. Must say an RS6 V10tt on full song is very nice - a hard-edged yowl.
