Auto Engine: Mazda rotary, MPS safe

Friday, October 23rd, 2009

Despite industry pressures to create more economical engines, Mazda intends keeping its rotary engine on the boil.

According to the company executive, the relatively thirsty powerplant will remain at the “technology core of the Mazda brand”.

Mazda’s Director and Senior Managing Executive Officer, Masazumi Wakayama said the rotary will continue to be the Mazda’s symbol in the future.

Mazda has also applied eco-friendly development to its rotary by way of hydrogen fuel.

The rotary engine boasts advantages over a conventional reciprocating engine, as it is currently used by the RX-8 and Premacy models for test purposes in Norway and Tokyo, because the combustion chamber is separated from the intake chamber, preventing incidence of pre-ignition of the highly flammable hydrogen fuel.

As far as the brand’s performance edge goes, its Zoom-Zoom — fun to drive — philosophy will remain, as too models like the sports-oriented MPS.

Mazda wants to expand MPS offerings in the future, but however Wakayama could not elaborate on Mazda’s future product details.

According to Wakayama, MPS is one of the symbolic models of the Zoom-Zoom strategy. It’s not an advertising campaign.

Wakayama can speak with some authority on the subject of rotary engines, having joined Mazda two years after the introduction of the powerplant in 1967 via the Cosmo Sport grand Tourer — the Japanese company’s original ‘halo’ model.

2009 Tokyo Auto Show: Toyota SAI Hybrid

Wednesday, October 21st, 2009

On the eve of the 2009 Tokyo Auto Show, Toyota has launched its new SAI, a sister car to the Lexus HS 250h in Japan. The 2009 Toyota SAI is a more affordable version of the Lexus hybrid sedan.

Toyota SAI with the four-door looks the same and the 2.4-liter hybrid system is identical. The SAI has a simpler interior and hits the streets for thousands less.

Toyota SAI is almost 4 inches shorter than the HS. It has changed new extensive sheet metal changes, including new lights front and rear, although these are so subtle that few will notice at first glance.

The SAI is being powered with the 2.4-liter hybrid powertrain with nickel-metal hydride battery pack mounted beneath the trunk floor, which is a straight carryover from the Lexus, making 187 horsepower.

Hybrids means green and the SAI turns in a useful 47-54 mpg in Japan’s economy cycle, exactly the same as the HS 250h, even though it’s smaller and up to 154 pounds lighter.

Japan gets the SAI because there is no Camry hybrid in the domestic market and its smaller body is better suited to Japanese driving conditions. For that reason, the SAI will not be crossing the Pacific to the U.S.

The Toyota SAI is a reasonable value at the equivalent of $37,600, but the top-spec model is of $47,370.

The Toyota SAI seems to be a smart move, but with the HS 250h on which it’s based selling out in Japan.
