How far? About 373 miles (600 km), according to Volvo. For those of you familiar with trucking in the United States, that might not seem like a lot. Average long-haul over-the-road (OTR) routes will see distances over 500 miles (800 km) – a range that the Tesla Semi boasts on a single charge. That being said, it was only six years ago that Volvo released its first electrified FL and FE series trucks into the wild. The FL only had a max range of 186 miles (300 km), while the FE – Volvo's especially heavy-duty version, able to haul nearly double that of the FL – boasted a meager 124 miles (200 km) of range, more suitable for inner cities than open roads. Volvo's latest design on the FH truck gave it double the range of previous versions by creating what Volvo calls the "e-axle." A clever design that combines the electric motors and transmission in a single compact unit, making it more efficient as well as freeing up valuable space for more batteries. Volvo's clever efficiency hack: the "e-axle", combining the motors, transmission and trans-axles all in a single unit Volvo In the US, solo OTR truckers are only allowed to be behind the wheel for 11 hours before they're required to take a 10-hour break. There are a few caveats in the rules, but for the most part, one can expect a 10-hour break, giving the operator plenty of time to recharge their rig between destinations. No word yet on what the charging capabilities are or the size of the battery pack, but the previous FL and FE versions could charge in two hours using high-speed DC-to-DC power or in about 10 hours using conventional AC power to power up its 300-kW battery. Volvo's full range of electric heavy duty trucks Volvo Worldwide, cab-over truck designs – where the engine is mounted below the seating positions – are popular because the shorter nature of the truck means more maneuverability and longer trailers for cargo while still being within overall length restrictions imposed by most countries. It also offers much better visibility than the conventional "long-nose" design favored by Americans, where only trailer length is considered for length restrictions at 53 ft (16.1 m). Better visibility is crucial in places like Europe and Asia, where the roads are often narrow or winding. The cab-over design also lost favor in the US as it's simply not as comfortable for the long haul. Longer rigs offer smoother rides and less cabin noise. It's hard to get much quieter than electric though.
