The full-size Alphard Hybrid MPV qualifies as an Ultra-Low Emissions Vehicle (ULEV), achieving levels 75% lower emissions than the Japanese government's 2000 benchmark. The 2.4-litre gasoline engine has been developed specifically for use in Toyota's hybrid systems and features a high-expansion ratio cycle that raises efficiency and reduces friction.
In 2006, a Royal Lounge Alphard was introduced. It is a luxurious, four-seat version of the Alphard.
The Alphard Hybrid uses "by-wire" technology that monitors brake pedal pressure and vehicle speed in order to calculate the optimum hydraulic pressure. By-wire works with the E-Four to maximize the collection of kinetic energy from braking for conversion into electric power.
The Alphard Hybrid Minivan can generate up to 1,500 watts and is equipped with standard 100-volt AC power outlets, allowing a wide range of appliances to be used, such as laptops and emergency lights. The electrical outlets can also be used to recharge items such as power-assisted bicycles and electric carts, adding a new dimension to leisure activities.
The Alphard Hybrid also offers some advanced safety features not seen on other hybrids. In fact, standard on the "G edition" and optional on standard grades are ( with a G-BOOK compatible DVD voice navigation system):
- Blind Corner Monitor, which indicates the approach of other vehicles or pedestrians from the left and right
- Back Guide Monitor with a color CCD camera and voice-guidance function, which uses signals from a steering sensor to calculate the likely reverse path during reversing and display it on the monitor screen
- Lane-monitoring system that uses images from the Back Guide Monitor camera to measure the lateral distance to white or yellow lines on major highways and triggers an alarm when the distance falls below a pre-set level
- Radar Cruise Control, which uses laser radar sensors and steering sensors to keep track of the vehicle's lane and any preceding vehicle and ensures that a safe distance is maintained in accordance with vehicle speed
