DK Engineering is proud to be the UK exclusive agent for McMurtry, the British engineering outfit working towards creating the world’s greatest small electric cars for road and track use.
Operating at the leading edge of technology, McMurtry is working to develop the next generation of automotive innovation. The team is committed to raising the bar for electric vehicles, inventing, and proving new technologies to offer cars with unrivalled performance in dynamics, speed and range.
The McMurtry Spéirling has demonstrated the dominance of the fan-assisted downforce technology by winning the Festival of Speed, setting a new outright record up the iconic Goodwood Hillclimb. The new record of 39.08 was set during the 'Sunday Shootout' by ex-F1 driver Max Chilton.
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 PURE.
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 PURE 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.
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.
Production will be limited to 100 units. Existing deposit holders will receive delivery in 2025.
The validation prototype will continue to test in the UK 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.
The image gallery below features images of the Spéirling PURE along with a selection from the DK x McMurtry hosted private test-drive day back in April this year, where indiviguals were given the opportunity to get behind the wheel, experiencing the mind-bending Spéirling first hand.
