Mazda taiki concept

Mazda’s latest series of concept cars seem like odd organic cars that do not look like it may make it’s way into production form anytime soon, and the latest is the Mazda Taiki concept which continues to follow the Nagare theme established with the first car in the new concept line, the Mazda Nagare. Nagare means flow, and Mazda turned to nature for inspiration - using cues from natural flow lines all around us - shapes in sand dunes etched by the wind, ocean waves, lava flow down a volcano, and etc. All three design centers - US, European and Japan contributed to this series of concepts, with cars like the original Nagare coming from the US-based design center and the Mazda Ryuga from the Hiroshima Design Center in Japan. The Mazda Hakaze design concept came from the European Design Center. The Mazda Taiki is the fourth in the series, and this one comes from the Hiroshima Design Center team led by Chief Designer Yamada Atsuhiko. Every concept car represents a different segment of future cars, for example the Mazda Ryuga was envisioned as a future compact car. The Mazda Taiki points to a possible future design direction for Mazda sports cars. The stretched coupe has short overhangs and its interior has a liberating and free feel to it thanks to an all-glass canope. It has a drag coefficient of 0.25 and zero lift. Air is channeled through the front fender via a tunnel formed between the body and the rear fender - this creates downforce. This design concept is also used to unveil some technical goodies. The 2-seater Mazda Taiki is conceptually powered by the next generation RENESIS rotary engine engine called the RENESIS 16X. The engine will be mounted at the front and will power the rear wheels, a proven formula for a sports car. More details on that engine will come in a later post, but you’ll be pleased to know that Mazda is the latest manufacturer to jump on the twin clutch bandwagon. The RENESIS 16X engine will be mated to a 7-speed dry twin clutch transmission. Suspension is a double wishbone setup for both front and rear, and the car rides on 22 inch Enkei wheels wrapped with Yokohama Advan Super-E spec Prototype 007 tyres in 195/40R22 size. As for dimensions, the Mazda Taiki is 4620mm long, 1950mm wide, 1240mm tall and has a wheelbase of 3000mm.

The rear doors open in opposite direction to the front. Given this circumstance, access to its rear seat is more comfortable than those of any other coupe on its size. Its length is 4.46 m.

The Mazda RX-8 has a rotary engine of 231 hp maximum power with a six-speed manual transmission. It is the same as the model is still sold, with minor changes in the lubrication system. It is the only engine available for the new Mazda RX-8, therefore, there is no version of 192 hp.

It has a high power consumption, which also does not weigh much. The cars of similar characteristics (none of them have rotary engine) spend a lot less fuel.

The Mazda RX-8 model 2010 comes with a set of decorative elements in the body as an input of large air or on the front spoiler in the final part of the body.

According to Mazda, as well as fulfilling a decorative function, play a role aerodynamics. Does not appear that the new model has less aerodynamic drag at forward because there is more speed to the model it replaces, or use less fuel.

Other changes in appearance are the tires that are 19 "in diameter (made of forged aluminum), changed the headlights and pilots (who are now LEDs) and exhaust are larger.

The dashboard is different. Instrumentation, is now a variable red zone, which is more or less extensive depending on the temperature of the engine (BMW also uses a similar system on some models). The steering wheel and seats, also manufactured by Recaro, are new. The body can be painted in four colors.

The equipment includes air conditioning, stability control (DSC), connection 'Bluetooth' for the phone, web browser, access system and keyless start, leather upholstery, heated front seats and electric adjustment for the driver's seat. Optionally you can have limited slip rear differential and adjustable dampers harder than standard.

The most important engine of the Mazda RX-8 from the previous 2010 model, is in the lubrication system. The oil pump is driven by an electromagnetic system (instead of a mechanic) and is placed in a different place.

The capacity of engine oil changes from 6.9 to 7.0 l and the letter has a different design to improve the lubrication when the lateral acceleration is very high. The rod is used to control the amount of oil is now located on the deck of the engine (the previous model had a side of the engine and it was difficult to insert in its housing).

According to Mazda, the inlets on the front of the body are higher than the previous model, the oil is cooled more equal speed (low temperature 6 º to 234 km / h, which is the maximum speed).

Mazda RX-8

The Mazda RX-8 has a more rigid chassis structure, changing the bar joining the support of the front springs (now trapezoidal section, instead of round). This new bar, along with other changes in the structure, makes the body of the Mazda RX-8 2010 is stiffer than the previous model.

The wheels have a different alignment and one arm of the rear suspension is slightly thicker to better monitor the adjustment of convergence. The cushions are manufactured by Bilstein. The fuel tank has more capacity (65.4 instead of 61.8 l l).

In the transmission system there are three changes. First, the manual gearbox six marches is different (as Mazda is similar to that of the MX-5, albeit with some changes, as the engine of the Mazda RX-8 has more power).

Second, the shaft (the part that transmits power from the gearbox to the rear differential) is more rigid (about 30%). Third, the rear differential has been changed now because a larger reduction (according to Mazda), but the final development of the Mazda RX-8 (32.2 mph 1,000 rpm) remains similar to the previous model.

This may be due to the reduction that makes the new gearbox is smaller than before, thus compensates for the further reduction of the differential.
