CFMA Nanjing factory shoulder to the achievement of Mazda in China’s mid-term goal – “2010 Marketing 300000″ – programs, and Mazda raised in the “2010 global sales of 1.6 million” heavy responsibilities. Mazda in the pursuit of driving pleasure and environmental protection, harmonious and safe performance at the same time, China will provide customers with the many “Zoom-Zoom” new product concept.

The Mazda rx 8 was designed as a front mid-mounted, rear-wheel drive 2+2 coupe. The car has a near 50/50 weight distribution, achieved by mounting the engine behind the front axle and the gas tank ahead of the rear axle. Weight is trimmed through the use of materials such as aluminum (hood, trunk, roof, and rear doors), fiberglass for the body panels and a carbon fiber composite drive shaft.

The car features a pair of rear-hinged “freestyle” doors (similar to suicide doors) in order to provide easier access to the rear seats. The Mazda rx 8 has no B-pillar between the front and rear doors, with the leading edge of the rear door acting as a ‘virtual pillar’ to maintain structural rigidity. Because of the overlapping design, the rear doors can only be opened when the front doors are open.

The Mazda rx 8 is powered by a 1.3 L (1,308 cc) naturally-aspirated RENESIS 13B Wankel-type rotary engine, which features newly designed side intake and exhaust ports. The engine is smaller and lighter than previous rotaries, primarily due to the lack of a turbocharger and associated parts. Though the engine is only 1.3 L, it is rated to get 18 mpg in the city.
The engine is designed in various configurations for different models, but in its most powerful setup develops 250 PS (247 hp, 184 kW) at 8500 rpm with a sustained red line at 8500 rpm, peak red line of 9000 rpm and fuel rev limit/cut-off at 9500 rpm. It won the International Engine of the Year and Best New Engine awards in 2003 and holds the “2.5 to 3 liter” size award for 2003 and 2004.

The Mazda MX-5, also known as Miata (pronounced /miˈɑːtə/) in North America and Roadster in Japan, is a lightweight two-seater roadster, of front engine, rear wheel drive configuration, built by Mazda in Hiroshima, Japan. The model was introduced in 1989 and continues to be a best selling convertible. There are currently three generations of MX-5, with the current (NC) model having been in production since 2006. Now in its third generation, the MX5's first generation, the NA, sold over 400,000 units from 1989 to 1997 – with a 1.6 L (98 cu in) straight-4 engine to 1993, a 1.8 L (110 cu in) engine thereafter (with a de-tuned 1.6 as a budget option in some markets) – recognizable by its pop-up headlights. The second generation (NB) was introduced in 1998 with a slight increase in engine power; it can be recognized by the fixed headlights and the glass rear window. The third generation (NC) was introduced in 2005 with a 2.0 L (120 cu in) engine. It was launched at a time when production of small roadsters had fallen into almost total disuse. The Alfa Romeo Spider was the only comparable volume model in production at the time of the MX-5's launch. Just a decade earlier, a whole host of similar models - notably the MG B, Triumph TR7, Triumph Spitfire and Fiat Spider - had been available. The MX-5 was conceived as a small roadster – with light weight and minimal mechanical complexity limited only by legal and safety requirements; technologically modern, but a philosophically direct descendant of the small British roadsters of the 1960s such as the Triumph Spitfire, Austin-Healey Sprite, MG Midget and Lotus Elan. The MX-5 was designed with a traditional front-engine, rear-wheel drive layout and four-wheel independent double wishbone suspension. It has a longitudinally-mounted four cylinder engine coupled to a manual transmission (5 speed for NA, 5 or 6 speed in NB & NC); an automatic transmission is a cost option. The body is a conventional, but light, unibody or monocoque construction, with (detachable) front and rear subframes. The MX-5 also incorporates a truss marketed as the Powerplant Frame (PPF) which connects the engine to the differential, minimizing flex and contributing to responsive handling. Some MX-5s feature limited slip differentials and anti-lock braking system. Traction control is an option available on NC models. The earlier cars weighed in at just over a ton, with engine power output usually 116 bhp (87 kW). The later cars were heavier, with higher power engines. With an approximate 50:50 front/rear weight balance, the car has nearly neutral handling. Inducing oversteer is easy and very controllable, thus making the MX-5 a popular choice for amateur and stock racing, including, in the USA, the Sports Car Club of America's Solo2 autocross and Spec Miata race series and in the UK the Ma5da racing championship. Beginning with the third generation, Mazda consolidated worldwide marketing using the MX-5 name, though enthusiasts in the USA still refer to it as Miata, a name that means "reward" in Old High German. The MX-5 has won many awards including Wheels Magazine 's Car of the Year for 1989 and 2005; Sports Car International's "best sports car of the 1990s" and "ten best sports cars of all time"; 2005-2006 Car of the Year Japan; and 2005 Australian Car of the Year - and making Car and Driver magazine's annual Ten Best list 10 times.

The majority of drivers will find that the 2010 Mazda MAZDA6 2.5 Liter V4 engine is sufficient for their needs, but if a person truly wants a powerful and impressive option, the 2010 Mazda MAZDA6 3.7 Liter V6 engine is the obvious choice. While the fuel economy may not be satisfactory to some consumers, the sheer enjoyment of driving a vehicle that has such an impressive power plant under the hood is often enough to make up for it.

This must be by far the most hilarious recall action we've ever heard about. It involves some 52,000 US-market Mazda6 cars from the 2009 and 2010 model years and a gasoline-loving spider. Yes, you read correctly; it's about a species of a spider that loves to build its web in the Mazda6 vent line, thus endangering the integrity of the gas tank.

“A certain type of spider may weave a web in the evaporative canister vent line and this may cause a restriction in the line," reads the National Highway Traffic Safety Association press release. "If this occurs, the fuel tank pressure may become excessively negative when the emission control system works to purge the vapors from the canister.”

What could happen is that “the stress on the fuel tank may eventually result in a crack, potentially leading to fuel leakage and an increased risk of fire,” adds the document.

The Yellow Sac spider, a common species in the US, likes the smell of hydrogen oxide that gasoline contains. The Mazda6 “has two pipes coming out from its gas tank, which is extremely rare and means that the smell of gasoline is strong enough to draw the spider in but not strong enough to kill it,” said Japanese automotive journalist Mitsuhiro Kunisawa quoted by Reuters, adding that there's no similar problem with any other Mazda car.

The remedy is to install a spring to prevent the spider from entering the vent line. The recall action will be free of charge for owners of the affected cars and will begin on March 25.
