Replying to: div2 (Aug 02, 2006 9:09 pm) Agreed 'Stang envy is not a problem here. An RX-8 sighted on the road still strikes me as "Wow that looks good, and I'm driving one". Where as the new 'Stangs looks like that '70ties show sans the chrome.

Replying to: trispec (Aug 03, 2006 2:10 am) While I do like the Mustang's looks, I chose the RX-8 because of my prior experiences with the RX-7 (owned a 79, 83 & 86). In 35 years of driving, I have never gotten as much reaction and praise as I have with my little red rocket. I didn't buy it for looks, I bought it because it's fun to drive & makes me feel like a kid again. I now have almost 9000 miles on the car & it's been virtually trouble-free. Also, gas mileage was better than I expected -averaged 23-24 mpg on the highway, with a few tanks at 25 mpg. Mazda needs to advertise the 8 more!!

I get around 13-15mpg in town in my 05 RX-8 GT w/6 speed. My commute is about 12 miles each way about 1/2 stop and go and 1/2 freeway. I drove a 380 mile round trip yesterday it was almost 100% interstate with only a couple of stops. Speeds were 60mph up to 73mph, depending on which state and if we were in town or not. For the first tank, I got 21.5mpg. For reference, in my 2005 S2000 I get 23-25mph around town and 27-29mpg on a trip - all with the top down. They only good news is that gas has dropped here to under $2.50 per gallon for premium. In the long term RX-8 test update in one of the car magazines, the commented on how expensive the 8 was to run in terms of always adding oil and how thirsty it was at the pump. "This is why no one else makes a rotary engine". The car is nice and fun to drive and the rotary is smooth, but I have owned 345 mph and 394hp (stock) cars that could deliver the same or better mileage and own a car with similar power and redline that gets a TON better.

Replying to: dwynne (Sep 24, 2006 9:14 am) I got 23MPG averaging 85MPH. I also believe, the RX-8 far surpasses all the competition. During the year I've own my RX-8 AT, I've driven 16K miles, where 6000 of those miles were highway. Long stretches of highway cruising needs a car to be roomy and comfortable, fun to drive, and capable of carrying the average U.S. family and all their weekend stuff.

Replying to: pathstar1 (May 13, 2006 1:46 pm) I bought a new Mazda RX2 in 1972, and loved the car, except for the gas mileage. And, as "pathstar1" says, apex seals were a problem. I loved driving that car, and gas was cheap at the time. |

Replying to: trispec (Sep 25, 2006 2:32 am)  I just report what I get. Driving around town there are lots of variables - do you redline, do you putt putt, etc. But on a trip where you just set the cruise and drive (straight line boredom) there is not much I could do to make it better or worse. Maybe after more miles are on my car the numbers will pick up. I agree that the car is unique - but that is not 100% a good thing. As I said I got better MPGs in cars with a LOT more horsepower than the 8 - the rotary is just horribly inefficient. Dennis

Replying to: dwynne (Sep 25, 2006 4:57 am) What does matter enormously, is having a car that pulls .93Gs through Boston's famous traffic rotary systems and winding cow path road layouts with three passengers. Makes the daily commute quite invigorating. Sure I pay 20% to 30% more for gas, but my passengers would much rather ride in my RX-8 than any other car. They pay me for the priveledge in fact. The car is known as "Therapy car" in my commute cycle.

Replying to: trispec (Sep 25, 2006 5:31 am) You must be short and have short passengers too. I love my 8 (except for the mileage, recalls, and lack of resale value) but my 6'+ sons really have trouble fitting in the car with me - and pretty much no one can ride behind me (and I am not that tall). But driving solo it is fine - and close to the thrill of the S2000. With a VooDoo knob the 6 speed in the 8 actually has shorter throws than the S gearbox - which has a very tight pattern. Lots of cars can do close to a g in a corner, and have more power to pull out of it. My M5 could, for sure I prefer a lighter, more tossible car however - which is why have both the s and the 8. Looking at the prices on the mazdaspeed6 I have been tempted to sell the 8 and get one (Mazda has a knack for making great cars that they can't sell) - but it is a good bit heavier than the 8 so ultimately would be less fun for me to drive. Ditto the new G35 - more passenger room, more ponies, better gas mileage, fewer (likely) recalls - but may not be as much fun. Enough of that, since this is the MPG forum - I will just state again 14-15mpg around town and 21.45 on a 95% interstate commute is lousy gas mileage for a small car. Good thing premium here is down under $2.50 a gallon  Dennis

Replying to: dwynne (Sep 25, 2006 7:28 am) Mazda was aiming at a price point, that's why the auto tranny can't go over 7500. An auto-tranny that can handle 9000 RPM starts to get expensive. The Caparo T1, needs a $13,000 paddled shifted 6 speed auto tranny to handle it's 12000 RPM racing V8. Sticks are definitely going the way of the dodo bird, I think. Beside Boston traffic jams pretty much destroyed my shifting knee and angle after 15 years of sticking it. |
