US manufacturer Entegra Coach has unveiled the Embark electric motorhome built on a Harbinger chassis. A 140 kWh battery powers the electric motor producing around 440 hp and supplies household appliances after stopping. Electric-only range is 160–177 km, rising to 724–805 km with a 1.6-litre petrol generator. The motorhome is about 9.4 metres long and sleeps four. Prototypes are undergoing real-world testing, including rental use; sales are expected in 2027 at a preliminary price of around $400,000.
