Gould GR59 – The Details

Now that the much-anticipated new Gould GR59 has been seen in public, we thought that we would have a little look at some of the finer points of this beautifully put together hillclimb car.

Starting at the front of the car, probably the most striking feature of the front suspension is the use of carbon fibre pushrods. This spun carbon tube has a titanium boss bonded into each end to connect to the monoshock and the uprights. The titanium boss at the upright end also contains shims for adjusting the cars ride-height.

Moving back, one of the most obvious differences to the average hillclimb car must be the roll over bar. The roll hoop is manufactured from considerably smaller diameter tube than I can ever remember seeing on a modern race car. This provides an obvious benefit to the weight of the car (especially as this weight is high up) and should bring a small aero advantage as well, aiding airflow to the rear wing.

There is no compromise to safety as the hoop has passed its MSA Roll Over Protection test.

The rear suspension features a similar carbon fibre pushrod arrangement to the front, acting onto twin dampers (housed within the full length chassis) with an additional, large heave spring/damper unit.

One of the major features of all of the cars produced by Gould is impressive aero performance. From the BDA-powered Gould 84 - which received considerable input from Patrick Head at Williams Grand Prix Engineering - right through the GR37, GR51 & GR55 chassis downforce levels, drag factors & high-speed performance has been absolutely first class.

The GR59 is no different. The aero concept appears to lean very heavily on under floor performance and the whole car seems to have been conceived to maximise the floor & tunnel size. The entrances to the tunnels are beautifully sculpted and also feature a sidepod mounted vane which appears to feed the tunnels further back.

The expected performance of the under body is highlighted by what is the smallest rear wing on a new hillclimb car for at least 10 years. This set-up is more reminiscent of a Formula 3 circuit car than a hillclimb car, and is considerably narrower, shallower and further forward than the liberal regulations allow.

A note of caution though; the Gould GR51, Pilbeam MP88 and the DTA Dallara V6 were initially debuted with very skinny rear wings back in the early noughties. However, due to a lack of aero balance front-rear they very rapidly acquired much larger and more complex appendages after early testing.

It will be interesting to see if Gould’s new floor can outperform previous iterations and allow them to reduce rear wing rather than increase it. The straight-line speed benefits of such little drag could be spectacular.

So there we have it, a quick tour around the new kid on the block. Only a brief scan of the more obvious details on the car, but hopefully we will be able to talk to David & Sean more formally later in the season and bring some more of the hidden secrets that this beasty contains to light.

In the meantime there will be a hunt for reliability with the car, which is inevitable for any car this innovative. I would bet that we will see Sean Gould ‘up to his elbows in GR59′ a couple more times this year, but I would also bet that we will see this model of Gould living up to the company’s reputation for stunning speed!

    Looks Great, can’t wait to see it for real. I note the front brake disks the same as on my car. Also the low slung calliper, nice touch. Can it do 120mph ess approach? Really no spy shots of the engine/transmission install?
