Toyota Alphard MPV Technological Marvel
MUSCAT — Toyota, a pioneer of clean, green hybrid technology, has now crossed yet another frontier.
It has done this by creating a new vehicle that proudly stands alongside technological marvels such as Prius. The new vehicle is a full-size MPV the Alphard Hybrid.
The Alphard uses the Toyota Hybrid System-CVT (THS-C). This comprises a 2.4-litre petrol engine and front and rear electric motors with a Super CVT continuously variable transmission and E-Four electric four-wheel drive system.
The E-Four system controls a rear-mounted electric motor that drives the rear wheels and controls the distribution of electric power to all four wheels. An electrically-controlled brake system (ECB) delivers efficient braking to each wheel individually for superior handling and safety.
Using “bywire” technology, it monitors brake pedal pressure and vehicle speed to calculate the optimum hydraulic pressure and works with the E-Four to maximise the collection of kinetic energy from braking for conversion into electric power.
The Alphard Hybrid qualifies as an Ultra-Low Emissions Vehicle (ULEV), achieving levels 75 per cent below the Japanese government’s 2000 benchmark.
The 2.4-litre petrol engine has been developed specifically for use in hybrid systems and features a high-expansion ratio cycle that raises efficiency and reduces friction.
Smooth performance is aided by power from the rear wheel motor being used when accelerating away from start-up or in slippery conditions.
The rear motor and differential form a single unit, so there is no need for a central propeller shaft.
This reduces the vehicle’s weight and so contributes to the Alphard Hybrid’s fuel economy.
The system uses a hybrid battery with an output greater than any other yet produced and offers excellent energy management.
The Alphard Hybrid can generate up to 1,500 watts and is equipped with standard 100-volt AC power outlets, allowing a wide range of household or business appliances to be used, such as hairdryers and microwave ovens.
The battery is located beneath the front seats, so does not compromise the vehicle’s luggage capacity at the rear.
The Alphard Hybrid also offers a package of advanced safety systems, including a blind corner monitor, which detects vehicles or pedestrians approaching from left or right, a back guide monitor with a rear-facing camera to aid reversing motions, radar-based intelligent cruise control and a lane monitoring system which measures the lateral distance between the vehicle and the margins of motorway lanes and sounds a warning if the car’s course begins to drift.
Toyota maintains proven leadership in innovating and establishing new standards in safety and technology. By focusing its enormous research and development — costing around $5 billion annually — Toyota achieves many breakthroughs. Toyota’s philosophy of continuously bettering its own standards allows customers to enjoy the best in technology, safety and value for money.
