2024 McMurtry Spéirling PURE

Taking the outright hill record at Goodwood demonstrated the performance potential of a modern fan car and in the process of doing so created automotive history.

Now it is possible to own an evolution of that record breaking vehicle, in one of the most extreme, no rules track cars on the planet: the McMurtry Spéirling PÚRE.

Its natural home is on race circuits, where McMurtry's bespoke fan downforce system gives drivers a step change in usable grip. It unlocks a new experience by delivering constant and approachable downforce, all of the time, regardless of speed. It is not affected by yaw angle or wind direction either. The sub 1000kg drivers car is focused on providing some of the most significant and talked about laps of an individual's endeavours on a race circuit, time and time again.

Direction changes are intensified. Senses are heightened as the rapid yet playful platform invites drivers to push harder than they thought possible. Braking and turn in points are redefined. Superior traction gives new operating regions to exploit on track. It's driving on a new level.

The downforce-on-demand system offers the greatest benefit to drivers where most time is spent on track, in the low and medium speed corners. Spéirling PÚRE owners will have the tools to access the G forces felt in top flight motorsport, as cornering in excess of 3G can be achieved even in some of the tightest corners on Grand Prix Circuits – for example 'The Loop' and 'Village' at Silverstone, or the famous Monaco hairpin if one can gain track access.

To truly cut through the air onto its way to a top speed of 190mph, and to optimise energy consumption, the streamlined body shape is vital. The frontal area is minimised by making the driver both the lowest and tallest point in the car and batteries occupy the space between the wheels and under the drivers legs in a Ú shape.This allows the cars frontal area to remain more akin to the classically proportioned 1960's grand prix racers at 1.02m tall and 1.58m wide (3.45m long).

The 18' tyres of section widths 270mm front and 300mm rear fill the arches with a powerful stance. When combined with the patented downforce-on-demand system, it is a recipe for total track domination. The intellectual property protection on the system means McMurtry are now the custodians of this era defining advantage.

Powertrain system performance and efficiency is balanced to maximise run time and minimise charge time, whilst delivering average lap speeds not seen before on many circuits. The cadence of driving and charging time fits nicely into the schedule of premium track programmes, such as the GT1 Sports Club, for which the Spéirling PÚRE is eligible. As a baseline the car is capable of doing 10 laps of Silverstone National at lap record pace and then fast charging in 20 minutes to run again. Tantalisingly the car has potential to go even faster, for a shorter qualifying simulation.

Production will be limited to 100 units. Existing deposit holders will receive delivery in 2025.

The validation prototype will continue to test in the ÚK and Europe in 2023 alongside pursuing a record-breaking programme. This will be followed by pre-production prototypes in 2024, ahead of production starting in 2025.

A single-seater hypercar, the Speirling occupies a footprint comparable to 1960s championship Formula 1 cars. This model, hand-built in the U.K. in 2023, is owned and driven by Sir David McMurtry and used to demonstrate the fan downforce-on-demand system. Evolving from the 2022 Goodwood Festival of Speed Hillclimb record-holder, the Pure delivers improvements in every area: 1000 bhp rear-wheel drive, top speed 190 mph, acceleration 0-60 mph in below 1.5 seconds. The only other suction fan cars in motorsport history were the Chaparral 2J and the Brabham BT46B. The Pure's patented fan and sealed skirt deliver constant downforce at any speed, for cornering and traction performance.
