2012ISF

not impressed and would never trade my F for it. Even if the M6 costs double.

We traded cars and went on the highway, the F just looks nicer and pulled better imo.
I also felt that the dual clutch on the bimmer was gonna go one day. It functioned normally and there was no problem with it, but I really didn't have faith in it. My buddy told me that those clutches eventually go and must be replaced and it cost a lot to fix.

I just didn't feel the security of solid reliability that I really feel with lexus. This is my 2nd japanese car, the first was a honda accord for the family. I come from a long line of german and a few american cars in my life and I will probably never go back. If i did and got a porsche again, I would be going into it knowing that I would be putting alot of money for maintenance and repairs. My last porsche 911 was a money pit.

Long Live the F!

Glad you could still choose the F after the more powerful and mod friendly M6. My parents have been long time enthusiasts of German automobiles, but as extensive an aftermarket support and the prestige they hold, they're not longevity type cars. Not all BMWs are money pits and not all Lexus are bulletproof, but enough of them are to keep me sticking to Lexus vehicles. On the flipside, my younger sister is looking into a V10 R8. Guess I'm the ugly ducking in the family...

I drove an M5 and wasn't impressed.

The V10 or V8 motor? I hear the new V8 is supposed to be pretty torque heavy and can up the boost. I figured they would pull pretty good.

The DCTs will eventually go. Its a real clutch, just like your normal 6 speed clutch will go out from normal use.

Which year m6? I believe isfpower here on the forums has the older model v10, I wonder what he thinks. Older one is 500hp, New one is 560. I also find it funny that the m6 highway mpg = isf city mpg

Oo we all know Euro V10s dont get good gas mileage lol. I am impressed with a 7.0L Z06 getting 17/26. My F doesnt get that good of hwy mileage and we have 2 more gears.

I got 27mpg cruising at 75mph with my F to work. I even took a picture of the cluster!

CUTigers

^^ ok you win, that is pretty good lol. But still, we do take 2 more gears to achieve it compared to the 6 speed.

Are the mpg for the is-f even accurate? I know for some cars (like the 2gs) they weren't completely accurate at all. Then again that technology was like 10 years ago

I know on the BMWs is just based on the air flow into the engine and stuff. I always reset one of my trip odometors every fill up to always have it for real.

On Lexus it's based on the #1 cylinder injector duty cycle. I also always reset Trip A for accurate mileage. The reported MPG can be very accurate or very different depending on your driving pattern. I have measured this more than once.

Yeah I have reset after every refil and the number is very accurate so far

It's because the z06 cruises at like 1700rpm at 80mph or something like that, I know it is under 2k rpm at 80mph got sure. We are at 2100rpm at 80mph

The good gas mileage of the ISF is like the cherry on top, but very few of us bought the ISF specifically for gas mileage. The fact that it avoids the guzzler tax is a big bonus for sure... but there are many other reasons that I'd rather have the ISF over an M6, and gas mileage is a ways down that list.

I just can't get over the way the M6 looks. The newer ones look a lot better than the first gen, but the car simply looks too big for a coupe for my tastes. If you're going to get a car that large, get the M5 instead. It's one of my main complaints about the GTR as well, even though I know the car is amazing on paper. I don't like big, bulky coupes.

26.2 - 26.4 mpg is usually my average on cruise control between 75-78. The route I take is flat with usually no tail/head winds
