The notorious apex seal from an RX-7 13B rotor

In my video describing the border of the RX-8, viewers rightfully stated that I contrasted model year 2015 vehicles to a 2011 design in regards to fuel economy, which to be unfair on Mazda’s end. Let’s best this wrong, utilizing the RX-8’s first model year.

Car Engine Size Weight Power MPG linked Rating
2004 Mazda RX-8 1.3L Wankel 3053 lb (1385 kg) 197-238 HP (Auto/Man) 18 mpg (13L/100km)
2004 VW GTI 1.8L I4 2934 (1330 kg) 180 HP 24 mpg (9.8L/100km)
2004 Corvette 5.7L V8 3214 lb (1458 kg) 350 HP 20 mpg (11.8L/100km)

As you have the right to see above, the RX-8 doesn’t ridge up favourably in terms of fuel economy. The Corvette, through a substantially larger engine, 47 per cent more power, and also five every cent more weight tho manages 11 per cent far better fuel economy. It’s likewise worth stating that this to be the very first model year for the RX-8, if the Corvette and GTI engines had actually been around from vault years. Fairly simply, yes nothing good to say about the RX-8 in regards to fuel economy. Back the buyer may not necessarily view this together a an unfavorable point, without passing emissions there is no automobile to buy.

It’s precious noting that due to the fact that the original publishing that this article, Mazda has actually announced it will bring back rotary engines, although only as little range extenders in electric vehicles. In various other words, nothing that will go ‘braap’.
