I’m a little out of step with the mainstream when it comes to electric vehicle efficiency. I believe that as long as your electricity is clean and your battery has enough run time to get you where you go (with the occasional DC fast charge for a longer trip), even the least efficient EV will beat anything with it. an internal combustion engine, especially if that electric vehicle is replacing something inefficient like a sports car or a large SUV. Most people think that this idea is not enough, however, and whoever can get it the most with the fewest kWh wins.
Since Thursday, there is a new winner. A British veterans non-profit organization called Mission Motorsport spent 24 hours driving a pair of Renault Zoes (with 52 kWh batteries) at the Thruxton circuit in England. The 2.4 mile (3.8 km) circuit is one of the fastest in the UK, but Zoe’s record averaged around 19 mph (30.5 km / h). It was good for 475.4 miles (765 km) on a single charge, which equates to 9.14 miles / kWh (14.71 km / kWh).
The winning Zoe was completely standard, with the exception of a set of tires developed by a company called Enso. The second Zoe raced on its factory-fitted rubber and did 424.7 miles anyway. This is much better than the car’s WLTP range of 245 miles (394 km) and corresponds to an efficiency of 8.16 miles / kWh (13.13 km / kWh).
“Thruxton was the obvious choice for this record attempt, but although it was the fastest track in the UK, the key to reaching 475.4 miles was finding the optimum speed and a smooth ride and consistent, ”said James Cameron, CEO of Mission Motorsport, in a statement. “Backed by Enso’s unique EV tire technology, we were sure we could break the record, but what we couldn’t have predicted was the incredible difference in efficiency, distance and feel with Enso tires. “
Mission Motorsport said its goal is to break a 2018 record set in France, which also came from a Renault Zoe. This attempt used a Zoe with a 41 kWh battery and traveled 351 miles (565 km) before stopping. Unlike this week’s Mission Motorsport event, this demonstration took place on the Paris ring road. Driving on public roads required a higher average speed – 27.7 mph (44.6 km / h) to be precise – and resulted in an efficiency of 7.9 miles / kWh (12.7 km / kWh).
In fact, there is a more impressive hypermiling record, also from 2018, which has also just been dethroned. This record was set using a Tesla Model 3, which spent 32 hours circling a 1.6 km loop in Denver. During this time, the Model 3 completed 606.2 miles (975 km), and while not particularly happy at the end of the marathon, it managed to cover 9.09 miles (14.68 km) for each kWh used.
The record for the longest distance an EV has traveled on a single charge is 999.5 miles (1,608.5 km), set by a specially modified BMW in 2017 – it likely won’t be in danger for some time.
