A New Era in EV Performance: The McMurtry Spéirling
Written on
Chapter 1: The Rise of a New EV Champion
The automotive landscape is witnessing a remarkable shift with the emergence of the McMurtry Spéirling, a vehicle that challenges the long-held supremacy of Tesla. For years, electric vehicles (EVs) struggled with performance issues, often regarded as sluggish compared to their combustion-engine counterparts. However, everything changed with the debut of the original Tesla Roadster in 2008, which unveiled the potential for EVs to be incredibly fast. While combustion vehicles still dominate racetracks, the title for the quickest accelerating road car has been claimed by electric models such as the Tesla Model S Plaid and Rimac Nevera. Now, an unexpected contender has entered the arena, outpacing both Tesla and Rimac in the 0–60 sprint, outperforming Formula 1 cars on a circuit, and boasting an impressive 350-mile range. Welcome to the extraordinary realm of the McMurtry Spéirling.
Chapter 2: Record-Breaking Performance
Recently, Mat Watson from the CarWow Channel took the McMurtry Spéirling for a spin at the renowned Silverstone Circuit, overseen by former F1 driver Max Chilton. During this exhilarating experience, the compact powerhouse achieved an astonishing 0–60 time of just 1.4 seconds, reached 100 mph in a mere 2.7 seconds, and completed the quarter mile in an incredible 7.97 seconds. At first glance, the 0–60 times of these high-performance cars may appear similar; for instance, the Tesla Model S Plaid clocks in at 1.99 seconds. However, the Spéirling is actually over 30% faster than the Plaid.
To put this into perspective, my old VW Golf 1.4s achieves a 0–60 time of 8.8 seconds, while a BMW Z4 3.0i, which is 30% quicker, reaches 0–60 in 6 seconds. I once attempted to match a Z4 off the line in my Golf and felt as though I was standing still as the BMW sped away. Anyone trying to race a Model S Plaid against the Spéirling would likely experience the same overwhelming sensation of being left behind.
The quarter-mile time of 7.97 seconds sets a new benchmark for road cars. For comparison, a Dodge Demon, engineered for rapid quarter-mile performance, manages it in 9.65 seconds—nearly 20% slower. The Rimac Nevera previously held the record with a time of 8.582 seconds, which pales in comparison. It’s noteworthy that the Spéirling's performance was somewhat restricted during this run due to gearing that capped its top speed at 150 mph, which it achieved in just over 5 seconds. With alternative gearing, McMurtry could push the Spéirling to even more impressive times.
Chapter 3: Engineering Marvels Behind the Spéirling
What enables McMurtry to achieve such feats? The Spéirling is a diminutive single-seater, weighing in at under 1,000 kg (2,200 lbs) despite housing a 60 kWh battery pack, making it one of the lightest EVs on the market. Coupled with 1,000 horsepower, it boasts a power-to-weight ratio exceeding one horsepower per kg. In contrast, the Plaid offers just 0.44 horsepower per kg, while the Nevera provides 0.84 horsepower per kg.
However, simply reducing weight and increasing power isn’t enough; without proper traction, the vehicle would struggle. This is where the Spéirling's innovative fan system comes into play. The car utilizes powerful fans to generate downforce by drawing air out from underneath it, creating an astonishing two tonnes of downforce when stationary. This technology allows the Spéirling to transfer all its power to the ground efficiently, resulting in its remarkable 0–60 time and superior cornering capabilities compared to other high-performance vehicles, including race cars. This capability enabled the Spéirling to set a new record at the Goodwood Hill Climb, surpassing both the VW IDR and even F1 cars.
While a single-seater like the Spéirling may not fit the traditional definition of a Grand Tourer (GT), it surprisingly offers practicality. The fan-based downforce system is more efficient than conventional wings and splitters, leading to a lower drag coefficient when the fans are inactive. Consequently, despite its modest battery size of 60 kWh, the Spéirling can achieve a range of 350 miles per charge (WLTP) or sustain high performance for 20–30 minutes on a track. Prolonged sessions would likely be limited by the immense G-forces experienced by the driver. Additionally, the Spéirling supports rapid charging at over 200 kW, allowing a full charge in under 30 minutes—ideal for track days.
In conclusion, it will be nearly impossible for competitors like Tesla, Rimac, or even Lucid to surpass the Spéirling without developing their own fan-based designs. Simply increasing power in their existing vehicles would likely exceed their grip capabilities. Thus, the automotive world has a new, unparalleled champion in the realm of electric performance.
