Ford Focus

As performance brands go, Ford's RS badge belongs very much in the premier league.

With a heritage stretching back to 1970, the Blue Oval maker's most coveted letters are held in reserve and applied only to the company's most focused high-performance machinery.

RS versions of the Escort, Capri and Sierra all hold a special place in the hearts of enthusiasts and in more recent times, it's been the Focus RS that's carried the torch with no little distinction.

This third generation version was the 30th RS-badged model to take its place on Ford's roll of honour. So, a little history before we start.

Focus RS models started with the MK1 model of 2002, a car that, looking back, seems rather feebly-powered with 215PS on offer from its 2.0-litre turbo motor.

The second generation version of 2009 was a more serious bit of kit, with 305PS on tap and clever RevoKnuckle front suspension that just about managed to tame all of the 2.5-litre turbo's unit's prodigious torque through the bends.

Adding the further firepower that Ford knew would need to be part of this MK3 model was always going to necessitate four wheel drive and, sure enough, that's what we got when this third generation car was first announced in the Summer of 2015, the first all-wheel driven Ford RS model since the Escort RS Cosworth of 1992. That Escort was primarily designed to win in the World Rally Championship.

This Focus though, was put together very much with ultimate road performance in mind.

It used much the same 2.3-litre EcoBoost four cylinder turbo engine featuring in the brand's Mustang muscle car but added in a twin-scroll turbocharger and a unique Cosworth cylinder head, these tweaks boosting power to 350PS.

To send drive to the rear wheels required a complete rethink of the body, which had extra strengthening to cope.

As for the back axle, it did away with a traditional differential and used clever gears to direct power between the wheels.

This is what let this RS perform its party piece in 'Drift Mode', where you can slide the car like a rally driver. It was all enough to create a package more than strong enough to trouble ultimate super-hatches of the 2015-2018 era like Audi's RS3 and the Mercedes-AMG A45.

Yet it sold when new at the kind of much more affordable price you'd have paid for merely very quick hot hatches like Volkswagen's Golf R and Honda's Civic Type-R.

Two run-out special editions were launched in 2017, the 'Red Edition' and the 'Heritage Edition'.

So does the Focus RS add up as a used buy? And even if it does, is this Focus RS too radical, a specialist machine only for collectors and enthusiasts.

Time to find out.

RS Fords have never been shrinking violets from a styling perspective.

Fierce bodykits and super-sized rear wings big enough to hold a board meeting around have long been the order of the day, a theme this third generation 5-door-only Focus RS continued in its own muscle-bound style.

You get that with rivals too of course, but with most of those cars, you're looking at exterior embellishments made to a standard bodyshell.

In this case though, things were fundamentally different under the skin, courtesy of the strengthened chassis necessary to cope with 4WD and the extra performance on offer.

Virtually all the other mechanicals used in this car are bespoke too - the engine and the drivetrain obviously, but also the suspension and the steering too.

No half-measures then. Inside, you get grippy branded Recaro seats upgraded to race-style 'shell' status in a move that gives the cabin more of a rally-style feel.

We're not quite so keen on the look of the leather-stitched flat-bottomed multi-function steering wheel: it's OK in a Focus ST, but something a little less mainstream was, we think, required for this RS.

Another feature shared with the ST is the bank of three extra gauges on top of the dash.

These deal with turbo boost pressure, oil temperature and oil pressure and are there to serve as a nice visual throwback to legendary fast Fords of the past like the Escort Mexico. In the rear, fears that the curved rear roofline might severely compromise headroom turn out to be groundless.

A couple of six-footers can be decently accommodated, though the wedgy side profile does hem you in with a slightly higher windowline.

And the boot? Well rear cargo space was always an achilles heel of the standard Ford Focus from this era and having to package in this RS model's 4WD system made things even worse here, reducing the 316-litre total you'd get in, say, a Focus ST from this period to just 260-litres here - less than you'd get in a Fiesta.

Still, look on the bright side: that's only 20-litres less than you'd get in a rival Audi RS3.

As with any hot hatch but especially with this one, you'll need to be careful and avoid thrashed and chipped-up examples.

Check the bodywork for signs of off road excursions and crash damage.

Damage to the expensive alloy wheels will be pricey to fix.

Examine the condition of the Recaro seats and make sure all the electricals work as they should.

Our owner survey revealed a few issues relating to a leaking head gasket on the engine.

A plume of white smoke on start up is the usual sign, and a small number of owners have even needed new engines.

Apparently, the wrong head gasket could have been used initially in the factory, leading to overheating problems, but these are rare - though you might want to check with the previous owner about any issues.

As usual, check that the service book is fully stamped up to date.

(approx based on a 2015 Focus RS - Ex Vat) An air filter costs around £11-£17 and an oil filter costs around £7-£10.

Brake pads costs around £33 for a front set and in the £25-£47 bracket for a rear set.

A radiator is around £100.

Wiper blades cost in the £10 bracket.

A water pump is in the £55-£83 bracket.

A headlamp is in the £150-£190 bracket.

Expectations are always high when you set out to drive an RS model from Ford - and particularly so here given that this third generation Focus RS was at launch the fastest model that had yet been made by the Blue Oval company's performance sub-brand.

Under the bonnet, there a 2.3-litre EcoBoost turbo engine capable of powering you from rest to 62mph in 4.7s en route to 165mph.

More impressive than the sheer speed though, is the sheer traction on offer.

The clever all-wheel-drive system is much more sophisticated than that used by rivals, featuring two electronically-controlled clutches at the rear that can switch up to 70% of the torque rearwards and up to 100% from side to side to maximise traction and forward motion. You can also tweak the powertrain's distribution of power through the standard 'drive mode' system which also deals with five other parameters - damping, throttle response, exhaust note, stability control thresholds and steering feel.

Choose from 'Normal', 'Sport', 'Track' and 'Drift' settings, the last one for tyre-smoking power drifts and for test track use only.

Use this Ford in a more conventional manner and it offers 36.7mpg combined consumption and 175g/km carbon dioxide emissions.

Some rivals with DSG dual-clutch gearboxes are more efficient, but we love the precision and feel of the RS's six-speed manual transmission.

The steering is also brilliant to use and the whole experience is accompanied by a wicked crackle from the twin performance exhausts.

You'll love it.

Great things were hoped for from this third generation Focus RS and great things were delivered.

Before we tested it, our only fear was that Ford's enthusiastic development team might have created something almost too good, perfect for extreme performance on track, but less impressive as a day-to-day driving machine. In the finished product, there are certainly elements of that - the infamous 'Drift' mode for example - but largely, what was delivered here met the brief: namely, to create the ultimate road-ready hot hatch.

Be in no doubt that that's what this is.

Given the badge on the bootlid, we never really expected anything less.

As a used buy, you'll need to be careful and avoid thrashed and chipped-up examples.

And you won't get the solid build quality of a comparable BMW, Mercedes or Audi uber-hot hatch.

But find a good MK3 Focus RS, then get it on the right road, race track or airfield and you won't care about any of that.

Tyre-smoking fun is guaranteed.
