Independent dealer’s take on a tuned Mustang V8 is hugely fast and dramatic, but will need ordering with restraint to work well on British roads

Our Verdict

Ford Mustang V8 Fastback

The Ford Mustang is available in the UK in right-hand drive for the first time, but does the rest of this American muscle car fit the UK car scene?

    Ford Shelby Mustang GT350R 2017 review

    Ford has tried to turn the Mustang into a track machine by putting it on a diet and giving it a new engine. Has it worked?

What is it?

The Sutton CS700 is a Ford Mustang V8 taken into a higher and altogether sillier performance dimension by London-based independent supercar dealer Clive Sutton’s new tuning offshoot, Sutton Bespoke.

It’s for anyone whose response to driving the standard 410bhp Mustang V8 is, “yes, it’s lovely – but could you do me one with about twice as much grunt?” Ford of Britain doesn’t cater to that particular niche, having no plans to import the current Shelby GT350 or the GT350R to these shores. And as long as that continues to be the case, the way is open for tuners like Sutton Bespoke to make and sell extra-special Mustangs to anyone who wants one.

It could be argued, of course, that the CS700 takes the Mustang’s pace beyond the reach of even the 526bhp GT350R. A twin-screw-type supercharger (sourced from the superbly named Whipple Industries of Fresno, California) takes the peak outputs of the Ford’s 5.0-litre cross-plane-crankshaft V8 to an improbable-sounding 700bhp and 674lb ft. The power and torque comes also thanks in part to a new quad exhaust system, a larger throttle body and an enlarged carbon fibre induction plenum.

If that engine conversion is all you want, Sutton Bespoke will provide it for less than £14,000 over and above the price of your car. But to get the CS700 in the ‘lower than a snake’s belt-buckle’ full effect you see in our photos, you’ll need to shell out a further £5500 for KW ‘V1’ lowered coil-over suspension and painted 20in alloy wheels. And then another £9400 for the carbon fibre rockers, spoiler, bonnet, rear quarterlight covers and interior trim, as well as the ‘decorative’ air scoops just aft of the passenger doors.

What's it like?

Very noisy, very fast, very thirsty, very firm; and yet potentially quite usable and livable – if you get your order right.

We were loaned Sutton’s show car for this review: a bright yellow example dolled up for maximum visual impact, with every option fitted to it, and the lowest and most aggressive settings dialed into its suspension.

Discrete, it ain’t. In its noisy mode, that active exhaust makes the kind of racket that could silence a coach-load of teenagers from the opposite side of the motorway, while the naked carbonfibre bonnet doesn’t exactly compliment the bodywork with much in the way of visual subtlety. Those louvres and slots on the latter are functional things, though, preventing excess heat from building up around that 700bhp engine, and also allowing you to peer into the engine bay from behind the steering wheel. And while the sound the car makes may be loutish, it’s also fantastically characterful. The whine of that Whipple blower chimes in like a backing vocal for the V8’s guttural combustion lead instrumental. It’s glorious.

The supercharger’s effect on the engine’s production of torque isn’t as initially mighty or as linear as you might expect, though. Lock the car in an intermediate gear, flex your right foot to a given point on the accelerator’s travel and leave it there; you’ll find the car’s initial rate of gain isn’t actually that savage. But like a big turbo spooling gradually, the supercharger feeds in more and more boost as the revs rise – making the car feel as if it might be being driven forwards by a huge propeller in about six feet of water rather than pistons and compressed air.

Choose an appropriate stretch of tarmac – preferably one without a speed limit – take a long, full-throttle run at the car’s redline, and you’ll be left in no doubt whatsoever that the CS700 is a 700-horsepower car. But it’s a fairly heavy car too, and doesn’t erupt with mid-range torque like an Audi RS6 or a Porsche 911 Turbo S. In other words, if you’re not either brave or daft enough to keep the car pinned between 5000- and 6500rpm, you’re simply not getting your bang-for-the-buck.

Sutton’s suspension makeover does two important things for the CS700 necessary for the enjoyment of the car’s fearsome turn of speed: it creates the traction required to put the car’s power down from low speed, and also the outright lateral grip and stability (on smooth tarmac, at least) needed to carry the huge speed that the car so easily builds. Though it steers with a physically testing, leaden control weight, the car’s handling response is excellent and its roll control first-rate. You might imagine that a 700-horsepower Mustang would always feel like a triumph of power over grip, but in the CS700’s case you’d be surprised.

The inevitable elephant-sized compromise comes with the car’s ride, though – which is short, firm, aggressively damped and wholly unsuited to uneven British roads. As part of its suspension overhaul, Sutton takes a whacking 35mm out of the ride height of the standard Mustang at the front axle, and 25mm at the rear. Part of this is about ‘straightening out’ the natural cruising pitch of the car, and the better balancing of its grip levels. Fair enough. But taking so much travel out of the car’s suspension leaves little room in which the car’s dampers can work, and makes it feel harsh, unsettled and irritable during fast B-road driving. Often a bit unpleasant even on an averagely surfaced dual carriageway, too.

Adding so much tyre footprint and lateral stiffness into the Mustang’s makeup also makes it surrender its grip on the tarmac in less progressive and forgiving fashion than you might expect of a front-engined, rear-driven American muscle car. But the good news both here, and in connection with that uncompromising ride, is that you can tune and tweak the dynamic recipe of your CS700 to your own personal taste during the ordering process. So if you’d rather drift that carve your way through corners, and want to preserve at least some of the long-travel ride compliance of the standard Mustang’s suspension, you just need to say.

Should I buy one?

Sutton Bespoke’s programme of upgrades for the sixth-generation Ford Mustang makes it easy to add as much visual spice, performance clout and dynamic purpose to your car as you can afford – but what the company offers is better considered as a shopping list than the definitive hot Mustang.

The CS700 has a incredible powerplant that gives the Ford searing pace and fearsome performance character – and I can see a case for having the engine conversion done on a car of the right age and condition. But it also proves that you can easily go too far in search of added grip and dynamism from this American icon – which isn’t, and never will be, a true supercar-killer.

I’d wait a few years to buy an out-of-warranty car, and then I’d have the engine conversion, the carbon fibre sills and the spoiler fitted – and either the halfway-house lowered ‘sportline’ springs that Sutton offers, or the KW suspension tuned to my own very carefully decided settings. And even then, I’d be doing it knowing there are quicker and better driver's cars I might be spending the money on, and that I’ll probably end up more enamoured of the burbling, effervescent quality of the Mustang’s performance than its outright quantity.

Egh? 0-62 in 5 sec? Thats slower than the normal Mustang V8.

How is it possible that anyone would take a polluting piece of junk unsuited to British roads and spend even more money on it to make it even more polluting and even less suited to British roads? Can anyone see the sense in it?

Once again your ignorance knows no bounds! The Mustang is smaller than most Saloon cars like the Mazda 6 and Jaguar XF, whilst also polluting less than lowered powered V6 and i6 Turbo Diesel engines you get in a lot of Execs and Compact Execs. Your clear bias against American cars is laughably conspicuous. :)

Who cares how polluting a single car is? How polluting an industry is as a whole, yes, I care very much about that, but seriously, who cares about the drop in a bucket that one person can LEGALLY drive. Don't hate the player, hate the game. Change the laws. And they ARE changing.

Get back in your 2CV and tootle off to Menzies to buy a copy of "Yurt Monthly" please, no doubt picking up some lentils and the latest copy of the Green Party Manifesto whilst grassing up your next door neighbour to the Stasi for having nice curtains. As has been said, often before, cars like this sell in tiny numbers for those that want them. Their net contribution to alleged global warming, gridlock and de-population of the native song bird is minuscule compared to the millions of eco-friendly vehicles churned out by mainstream manufacturers. If you don't like it, don't buy it!

I was going to buy one but now, thanks to you, I might buy two :)

Just a shame they didn't tweak it to 600 kW to go one up on the Hellcats.

3 July 2016
What a shame that the bigger selling automatic version of this car only comes with a dated six speed automatic, when a factory homlogated eight speed auto mated to a factory supercharged version of this motor in the soon to be outgoing Australian Ford Falcon is currently available.
But then the factory joint venture between Ford and GM will soon bring to us a ten speed automatic and thus the Mustang will share the same transmission with it's arch-rival, the Camaro.

3 July 2016
That being said, with 700hp. The 5 sec. figure must be conservative. 4 sec. sounds more believable. Perhaps with a few test runs, it might brake the 4 sec. barrier to some slight degree.
However it must be very quick from 100 - 150km/h, or 150 - 200km/h.

3 July 2016
I'd probably take the engine mod, the carbon fiber bonnet, and beef up the brakes and equip it with the bigger tires -- but leave the suspension mostly unaltered from standard 5l. v8. Accepting the compromise that the monster performance would be more for straight line work, that one would have to temper ones ardor in corners in other words - that the car wouldn't thus be for track; and keep the every day usability mostly thus intact.
