Hybrid motorhome showcased at Monterey Car Week

The Entegra Coach Embark, a hybrid electric motorhome developed by Jayco under its Entegra brand, has drawn attention during the Monterey Car Week. The vehicle, expected to be available in 2027, measures 9.10 meters in length and weighs around 8.2 tonnes, with a price tag of $400,000 or approximately €360,000.

Technical specifications of the motorhome

The Embark is built on a commercial chassis designed by the Californian startup Harbinger and features a 446 horsepower electric motor powered by a 140 kWh battery. This allows the motorhome to drive about 180 km in electric mode, which is considered modest for a vehicle of this weight.

Range and energy system

The vehicle includes a 1.6-liter four-cylinder engine as a range extender, which recharges the battery without driving the wheels. With a full battery and a full tank, the combined range approaches 720 km. The design integrates the traction battery to power both driving and the living area, aiming to reduce reliance on an auxiliary generator.

Design choices and features

The Embark is smaller than some internal combustion motorhomes and does not include a slide-out feature, an American system that expands the living space when stopped. This choice is intended to limit weight, preserve autonomy, and improve durability, waterproofing, and thermal comfort. However, many buyers may judge a motorhome primarily by its length and habitable volume.

Price and market challenges

The high price of $400,000 is a potential drawback. John Harris, co-founder of Harbinger, highlights lower operating and maintenance costs as a compensating factor, though he does not quantify the difference. Entegra is still working on the dashboard interface, which is supposed to constantly inform the driver about the status of the powertrain and alleviate concerns about range.

Market reception and production plans

The model was presented in January 2025 and received a positive reception, but Jayco prefers to complete its tests before production. It is uncertain whether the Embark will easily find its audience, at least not in Europe, where this model should not cross the Atlantic due to a lack of demand at this level.
