Art Of Deception: The Hansen Motorsport S4

Next Chapter

Øystein knows a few things about When the owner, and brains Norway’s Hansen Motorsport supplying performance-orientated parts for people’s four-ringed machines, find him in his garage working on his

Earlier this month, on road to Gatebil Rudskogen, of the team dropped by to check out his but very impressive collection of metal.

And what a sight them in Øystein’s garage too – his 722hp/1130kg long-wheelbase Ur-quattro, and his and possibly most ambitious project thus far – an S90 sedan dealt the  full  GTO treatment.

You’ll get to to read both the Ur and the S90 in stories coming up but right now we’re going to a look at Øystein’s somewhat daily – a 2000 Audi B5 RS 4

Wait… what?

Anyone who anything about high Audi road cars know that in B5 chassis the pumped-out and powered-up RS 4 was only in five-door Avant wagon not as a four-door sedan as seen

That might be true a production car standpoint, but as you can perhaps tell, Hansen Motorsport the sort of company to let small get in the way of a good idea – especially the idea has an Audi badge on it.

In principle, and providing you can get your on all of the right parts for the job, a bespoke B5 RS 4 sedan from a B5 S4 is a pretty straightforward proposition.

in the sense that the majority of can be swapped over, save for the rear arches of course, are at one with the Avant’s rear

But this project was never about building an S4 into that simply looked an RS 4, but rather embodying Audi’s RennSport philosophy, and then things one step further. And no more evident than the bonnet where the 2.7-litre V6 engine base common to models – albeit toughened and to a solid 375hp in the standard RS 4 now generates some serious More than double the factory 260hp output in

According to Øystein, 550hp within the carbon-fibre-cloaked engine but the modifications required to generate rather impressive number are straightforward. Based on past there was no need overhaul the internals, only to simply add two of RS 4-spec cams. The rest of the are based on supporting a pair of turbochargers from LOBA

The LO600P kit is built around a of BorgWarner KO4 RS6 turbos – but they’re not off-the-shelf parts. The inlet been CNC-modified to take compressor wheels, and the turbine have been CNC’d for flow capacity. A bolt-on the turbos are mounted on S4 facelift exhaust manifolds, with an RS 4 RS 4 intake and a custom-built Hansen exhaust system.

The remainder of the engine upgrades around fuel and spark. a Bosch Motorsport 044 fuel an RS 4 fuel pressure regulator and and Siemens DEKA IV 630cc in the mix, with 2.0TFSI coils and a Hansen Motorsport for the S4′s Bosch Motronic management system.

Apart the carbon fibre shroud and air filters, there’s little to away just how powerful the S4 is the bonnet, and that build extends to the outside, where a simple case of less more. The front bumper is the RS 4 article, albeit customised by with a Seat Cupra R

The front fenders are Kevlar but the like the genuine RS4 doors and fenders, they’ve been in the right places for a little bit of width. The side skirts also been extended to give the illusion of a lower height and a genuine RS 4 Avant was fitted at the rear after modified to fit the sedan.

It’s easy to see that some hours have gone the bodywork, but Øystein’s a detail guy and somewhat of a perfectionist when it to achieving the desired look The finished result has definitely worth it though.

To fill out the Zito ZL111 alloys fitment provide an understated look. Unlike the Porsche GT2 calipers and Brembo 365mm package fitted on the front end make very clear Audi’s functional stance is enhanced by a performance suspension built around HR coilovers, and uprated front and rear bars.

Couple that with the factory quattro all-wheel system, and there’s no guessing why chooses to drive this car on a basis. And who in their right wouldn’t want to?

Pulling the look together are some carbon fibre accents – the stuff too I should add. The aero mirrors were made for the application.

As was the boot lip The perfect finishing touch for an yet still aggressive exterior

Inside, similar thinking has utilized. The space is clean and infusing track-spec seating the otherwise nicely appointed S4 interior.

A custom-built half has also been installed, an element of roll-over protection at the of carrying backseat passengers. But that only messes balance and the power-to-weight ratio right?

Sure, the factory leather-wrapped Recaros probably would provided a more comfortable than the RS4-emblazoned Recaro Position seats, but lateral was far more important to Øystein.

Because along with him to the supermarket, this is a car that properly used on the track – and

I’ve always had a soft for the B5 S4, but after seeing what done with his car, I’m not I could bear to own one any more taking a leaf out of his book! he could have started a genuine RS 4 Avant and undertaken a few to bring it up to spec, but that’s not this build was all about. It was taking something very and making it great.
