Disclaimer - I like the RX7.
Okay so on paper the Fairlady looks like it has everything. Bigger Engine, More cylinders, More powah, More peak torque. More PP. More weight...oh more weight, that isn't good, is it?
Looks.
The Fairlady is pretty good, At the time it looked "mean" the front end had a very purposeful look... which the Bugatti EB110 seems to have stolen with the fixed top lamps that are a close set. The RX7 FD is a thing of beauty though. But both cars had long production runs that didn't really muck about with the lines of the car. Honestly both are slinky cars that don't melt your retina to look at.
Drive
The Fairlady was
Mediocre - at times it almost felt like the rear wheels were doing some of the steering. It feels a bit sloppy and inconsistent - Drivable though but not as precise as you would first like it to be. Maybe the slightly pudgy handling will suit you. I remedy my qualms by looking at the badge - and being happy I'm not in a GT-R
understeeru edition. So for a front engined rear wheel drive car it isn't that great, but better than any front wheel drive horror show or a sports off roading 4WD car.
The RX7 though is just grand. Delightfully balanced, Makes car control almost effortless, it rotates easily - so if you are a ham fisted driver you will create your own problems (oversteer) - Nice and Gentle. Driving an RX-7 is very much like making love to a beautiful woman. You've got to appreciate the curves, and caress the bodywork. Breathe softly and gently. Then savour the smells,
"Is that Castrol R, You little minx!" (Censored)
Engine
The Americans have a saying - "
There is no replacement for displacement" Can a twin rotor 656cc compete with a big 3 litre V6? Both have turbochargers. To be fair you have to remember the Rotary engine doesn't have much low end guts, but a bit of novice stickwork will let you sit high in the rev range getting the car gorge itself on torrents of buttery smooth power. The Nissan's V6 is nice enough reves freely and it is a better part of the comparison, If you could swap the engines stats, then the RX7 would go evenfaster and the Fairlady would go slower but the reason the Mazda's engine is so modest is a major factor in the RX7's lack of ...
Weight
The English had a saying "
Simplify, then add lightness." Chunky Chapman would use this maxim to lead the world of Formula One. Less weight makes faster acceleration and less load in the corners, so your tyres can accept more speed. Also you can slow down in a shorter order as Physics tends to get a forceful when you have to deal with that pesky conservation of energy. 550lbs is a good old chunk of extra weight.
(That is like a B.J.Raji and a Mason Crosby sat in the car.) But to be fair I think you have to really say that the RX7 is lighter rather than the Fairlady is a bit of a plumper.
(Step away from the cake 300ZX) - The RX7 is a sporty car, and the Fairlady is more of a comfort tourer.
Paint Chips
Neither are amazing, the rest of the world version of the Fairlady has a few interesting ones, Deep Purple Metallic and a Dark Green
(Who doesn't like Dark Green paint? What are you, some sort of hairdresser?) But we are just comparing the Japanese Domestic versions, I think you have to just give this to the Nissan, but it is a pretty close thing and neither have huge selection and the Iconic colours are pretty evenly matched; The Nissan just has a bit more choice.
Lap Times -
I ran alot of track time at Yamaha's Sportland Sugo way up in the north of Japan. Rolling track just under 2 and a half miles in length. I dropped the RX7 down to Comfort Softs to be fair - Though maybe the Fairlady will be better if it stepped up to semi slicks like the RX7 is issued with. - On Comfort Softs both are good, the lack of grip magnifies the handling.
Sportsland SUGO - RX7 edged it by over a second.
I also ran it on a longer, more open track (Rebel Run a 6 mile Death Valley track) - I was pretty amazed that the Fairlady kept pace with the RX7 and after the third flying lap was 2 seconds faster - Yet at Sugo the RX7 was faster. So closer matched than I expected - In Fact I am still unsure as to which is faster. Logic would say a longer open track would favour the Nissan, a tighter technical track should favour the lighter Mazda.
The Mazda was more fun to drive - just from having to balance the car so alot of added fun in the corners. The Nissan was much more meat and potatoes and you had to drive allowing for the longer breaking time and the trick was driving to avoid, turn-in understeer - once that box is ticked the lap times tumble.
Verdict.
Closer than I expected, the
RX7 wins though, but once you get the feel for the Fairlady it can be quite fast.
