This is the brand new Toyota SAI, a new vehicle based on the popular Lexus HS 250h which will be showcased at this year's Tokyo Motor Show. The long rumoured SAI, will carry Toyota's new 2.4-litre Atkinson cycle combustion engine capable to develop 110kW (150 hp) at 6,000rpm and 187Nm (19.1kgf-m) of torque at 4,400rpm.
Although many of you would say the the resemblence with the HS 250h is obvious, Toyota says that the new SAI is four inches shorter and up to 70 kgs lighter than the Lexus. Regarding the design, this consists in a new front grille, different head and tail light treatment, wings and so on.
Although it is smaller and lighter, the Japanese automaker says that the new SAI will get the same 56-65 mpg as HS 250h in Japan's economy cycle and 101-107 g/km of CO2. Inside, the Toyota SAI is under the Lexus HS 250h in quality terms. The new hybrid car is priced from 3,380,000 yen or $37,127.
The Toyota Sai, which debuted during the Tokyo Motor Show in 2010, showcases what talent and technical expertise can do when combined. In fact, the hybrid-only sedan’s name is Japanese for “talent” as well as “color,” depending on the characters that were used.
As a tribute to the name, Toyota’s engineers came up with a sedan that combines performance, fuel efficiency and consciousness for the ecology. Even the materials used for the Sai have been chosen with an eye for the environment – Ecological Plastic, a material that is synthesized from certain plants.
Under the hood, the Toyota Sai features a 2.4-liter gasoline paired with an electric motor. This is Toyota’s proprietary Hybrid System, which also includes a reduction gear. The system is very efficient at managing heat, thanks to specially engineered movements in the valve.
Closure delays in the intake valve make high expansion ratio at low pressure possible. This motor is just one of the components of the Sai, of course – elements in the design bring about efficiency, and excellent performance through optimized aerodynamics.
Of course, the sedan is also designed to be visually stylish, safe and comfortable as well. These include a Pre-Cash Safety system, which makes use of a radar that can detect objects as close as several millimeters in distance. There are also features for cruise control, to make the Toyota Sai smooth to drive and control.
