Well its nice to know i am not alone in criticising the decision by MAZDA to bring out the automatic RX8.
These are the comments made by the jounalists from Wheels magazine Feb 04, pgs. 61, 110, 111 in relation to the automatic RX8:
"Mazda meanwhile got busted over its reluctance to hand out automatic RX8's to the press. They were firmly told that there could be no COTY (Car Of The Year award) consideration without it. Magically, they found one, and suspicions were confirmed when the four-speed, low-revving rotary drove like a DRUGGED DACHSHUND (breed of small dog). It became known as the six-cylinder P76.
(Hymee as an ex-P76 owner - are you reading this?)
The RX8 automatic, on the other hand, is not so satisfying. Mazda's decision to team the rotary with a four-speed automatic is hard to understand. Torque converters can't cope with high revs. Consequently, the auto RX8 redline is 7500 rpm, largely accounting for the loss of 36kW compared with the unrestricted engine of the manual.
The automatic's top gear is much taller than the manual's and with fewer gears to fill a wider spread, the gaps between ratios are huge. Compounding the problem further is the auto's electronic control software. To avoid shift shock and to ensure transmission durability, it will not allow selection of first gear from second at more than 45 km/h.
This equates to an engine speed of only 4600 rpm. The driver is denied access to the top half of the engine's operating range, where the rotary is at its best.
While the automatic RX8 performs reasonably well in undemanding situations, such as city or freeway driving, it cannot be recommended to an enthusiastic driver. Mazda should have given the RX8 the automatic it deserves - either a sequential, one of the double-clutch sequentials, or even a toroidal CVT; all would have been good choices. All of these technologies avoid the rev restrictions of a torque converter auto. Even a five-speed conventional auto would have been better."
** The words in brackets are mine
The good news is that even with the lame duck/dachshund of a dog automatic RX8 we still managed to win the coveted Australian Car Of The Year (COTY) award.
For all the automatic drivers - learn to drive manual so that in the future you can truly enjoy what a sports car is all about.
