‘Hypermiling’ is term that means to extract as much distance or endurance in a vehicle, and implicit in that practice is the idea of using the least amount of fuel, not exactly electrical energy, though the principle is identical.
Common techniques include feathering the throttle very lightly, avoiding uphill climbs, keeping the car in constant motion and not breaking momentum, folding door mirrors to increase aerodynamics, reducing unnecessary weight in the car, and turning off the air conditioning (among other energy draining functions).
Using a P100D, a pair of Belgian self proclaimed Tesla enthusiasts - Joeri Cools and Steven Peeters - have claimed to have broken the record for longest journey on a single charge on a Model S, breaking the previous endurance yardstick of 885.6km set in a P85D in 2015 by a Casey Spencer.
They claim to have driven 901.2km before the car called it quits.
Detailed in a blog post, the duo used a pre-planned 37.3km urban loop just northwest of Antwerp, and while it’s perhaps not as potentially efficient as driving on a single straight or banked loop, perfect conditions aren’t at all representative of real-world driving. In total, they drove their Model S for a marathon 23 hour and 45 minutes at an average speed of 38km/h.
We wonder how many pee bottles they had to take with them. They reported that the ambient temperature peaked at 25°C on that day. Cracking the window would increase aerodynamic drag, and therefore not really an option.
Upon catching wind of their endurance run, Tesla CEO Elon Musk tweeted and hypothesised, given the right tyres (designed for minimal rolling resistance), that the Model S should be able to crack 1000km on a single charge.
Given its performance and need for maximum grip, Tesla fits the Model S P100D from the factory with a set of Goodyear Eagle RS’ on the standard 19-inch wheels, though an upgrade to the larger 21-inch set brings with it Continental Extreme Contact rubber. The Model S P100D used in the test, affectionately named Roadrunner, seems to be riding on the smaller 19-inch alloys, which they revealed were wrapped with Michelin Primacy tyres.
We’re also sure that a single-motor P100 (non D, rear-wheel drive) configuration would have been the most ideal Model S to have used.
