Diesel BMW Driver Smashes Solo Coast-to-Coast Cannonball Driving Record (roadandtrack.com)
A traffic-free L.A. allowed Stowell to reach the Portofino Inn in just 27 hours and 16 minutes. That time absolutely smashed the previous verified solo record of 27 hours 54 minutes set by Carl Dietz in a Cadillac ATS back in April 2020. Stowell also beats the pre-COVID overall record of 27 hours 25 minutes set by current record holders Toman, Tabbutt, and Chadwick. He managed to do this by averaging a speed of 105 mph, with a top speed of 151 mph. He also had the benefit of only needing to refuel every 800 miles or so, owing to averaging around 23 mpg during the attempt.
.... Despite coming from a line of Audi S6 models, Stowell was convinced to purchase a 2015 BMW 535d by a buddy with an E90-generation diesel 3 Series of his own. The car isn’t exactly stock, with a stage 2 tune removing most of its factory emissions controls. An ECU tune brought output to around 400 hp and 560 lb-ft of torque, allowing for great passing power on the highway. A series of aftermarket fuel cells were installed before settling on the final unit, which was outfitted with some tank foam to limit fuel sloshing. This cut a few gallons out of the tank, but left Stowell with around 40 gallons of total capacity. An Insta360 radar detector was the main piece of anti-cop hardware, but Stowell didn’t run the several units we’ve grown accustomed to seeing in these cars. He told R&T that he plans to continue driving this BMW, and didn’t want to tear up the interior for this challenge. .....
