I hope we have enough strong voices to dictate thatwe do that with th is car.âThe concept sits on a unique platform and carries itscompact ro tary motor low and tight against the frontbulkhead. At 4389mm by 1925mm and 1 160mm, thetwo-seat er comes in shor ter, wider and lower than a 991Porsch e 911. âThe concept is on the larger si de, but theideal would be lightweigh t sports car with a very tautdesign,â continues Maeda. âThere are a number ofpotential materials, including carbon fibre and aluminium
- Mazda has the technology to exploit aluminium. If youconsider the price and engine performance [R880k and239kW for the 3.4 S] then perhaps the Cayman is anappropriate comparison.â Itâs a sentiment echoed by r&d boss Kiyoshi Fujiwara. âIfwe mass-produce this car then we would make it lighterthan a Cayman. We made the MX-5 a very light car. Weâddo the same with th is rotary.â All of which bodes well for a production coupe (andconvertible) with th e RX-Visionâ s styling and the RX-name. Fujiwara: âIn the past RX-7 was always a two-seat eror a 2+2. RX-8 was a four-seate r. If we call it RX-9 â six-seat er? You can imagine this carâs name.â Strengtheningthe case for a next-gen RX-7 was the reaction tothe car inTokyo: Mazda held sway over the kind of new-producthysteria normally reserved for a new iPhone. As for thetimescale, while a 2017 release would make for a neatanniversary launch â the original Cosmo ro tary debutedin 1967 â Mazda will have its work cut out to get the car ready. Alfaâs crack team may have create d the new Giulia in two years but they didn ât have the ro tary engine to contend with. Fond of bu rning fuel, slurping oiland merrily parping all sorts offilth from its exhausts, theWankel has caused Mazda nosmall amount of grief. It won LeMansfor them of course, and thethird-generation RX-7 FD isrightly regarded as one of Japanâsgreat sport cars but, as engineerFujiwara points out, th e ro taryâsalso been challenging. âWe havea solution now for the problemsbut we need to be su re it isdurable. We want to do two orthree times moretesting than wedo normally, beca use we havethis past ex perience of qu alityproblems and causing suchinconvenience to our customers.âWhy bother, you wonder?While there are advantages inthe ro taryâs strong output for agiven size and weight, and thetypeâs intrinsic smoothness, youget the feeling that, perhapscommendably, at Mazda heart isruling head.Maeda: âI owned one ofthe first RX-7s and a third-generation RX-7 FD, myfavourite. We feel that if wedrop the ro tary the technologywill disapp ear from the world.For that reason we have the mindset tocherish it. We would dearly like to race with it again too,and if we do Iâd like to be behind the wheel!âThe RX-Visionâ s beguiling form, weighing next to nothing,badged RX-7 and howling onto our ro ads just as a raceversion makes a triump hant return to Le Mansin the 201824 Hours?
