OK. I had an argument with a friend of mine in regards to the 1/4 mile and 0-100 mph numbers posted by Motortrend (335i vs G37).

0-100 mph
335i = 12.7 sec
G37 = 13.9 sec

1/4 mile
335i = 13.7 @ 104 mph
G37 = 14.0 @ 101 mph

My friend claimes that the G37 is catching up to the 335 because at 100 mph the 335 was 1.2 sec ahead of the G37 and at the 1/4 mile (wich is only a few mph faster) it was only 0.3 seconds ahead of the G37.

How can this be true?

I told him the 1/4 mile test and the 0-100 mph test are two different things.

What do you guys think?

No flamming...

You can be assured the that G37 will be faster than 101 in the 1/4th. The sedans (hell, even the old sedans) traps 101-102, sometimes even 103 with significantly less power. I understand the 37 weighs nearly 3700 lbs, but its putting down about 300 whp.

[Jonmartin]

The 335 will walk the G37 any day of the week.The only way the G37 will pull is if the 335 had two flat tires.

[ward]

do your really judge which car by how fast it is in the 1/4

both cars perform about the same

[Walked U]

If you looking at straight line performance just look at trap times.

As far as the twisties go, i wouldnt know.

13.7?? Edmunds had the 335I at 13.3 in the 1/4..

different environments (tracks and temps) would be my guess. Mike.

Where did you see 300 whp?

Edmunds got 286 whp...just like most of the 335 get.

[shiggy]

i could care less if a G37 is faster or slower than a 335I....i really dont think an infiniti can replicate the driving experience of that of a BMW!!!
On the highway...straight aways or through a winding road...its tough to beat a BMW!
there is not another car that is produced today in the price range of a 335I that can remove the smile on my face every time I get behind the wheel!
By the way...I ate a porsche for lunch today...yum!...man was he pissed!!!
cheers, shiggy

[BMW320i]

not sure about the numbers but:

BMW hp > infiniti hp

Yup, I got a 13.465 even at 2700 ft elevation LACR, and at Sea Level I definetly can get 13.2x in the 1/4 mile. So low 13's, not 13.7 seconds in the 1/4 mile.

[BMWPower06]

cant stand Infiniti's ive been a BMW boy since day one and for me it was clear 330>G35

Its been a while ago. Somebody posted up a dynapak readout comparing an 05 g35C 6 speed against the G37 6 speed. Old G did like 265 whp, new one did 298 whp, I believe.

0-100 mph

The difference lies, most likely, in a few areas:

First and foremost, two different cars tested on two different days and possibly different tracks or locations.

The other discrepancy is probably the shift points.
The 335i got to 100 mph 1.2 seconds faster than the G37 and only (in that example) .3 seconds faster in the 1/4 mile because of shift points.

Tell your friend to look at the trap speeds.
If one car crosses the line doing 104 mph the other doing 101 mph how is it possible the slower car is catching up.
The car that trapped at 104 will be going 3 mph faster than the other so the other couldn't possibly be catching up.

If the G37 was catching up the 1/4 mile times and speeds would look like this:

335i: 13.7 @ 104 mph
G37: 14.0 @ 104.5

Then the G37 would of been behind and still lost the race, but catching up because it had a faster trap speed.

[grkm3]

That is the worst 335 time I have seen.Show your boy some mags that got 13.4 at like 106 and see what he says.

[Driver72]

Oh, and as to "which will eventually be faster"
well, at this point that's hard to say.
I don't think the G37 would ever catch the 335i.
However, it IS possible that as speeds continue to climb the G37 might make up some lost ground.
By that I mean. Smaller displacement turbocharged engines begin to lose more speed than larger displacement higher revving naturally aspirated motors.
It will also depend on aerodynamics. I'd venture to say the G37 is more aerodynamic than the 335i coupe since the OLD G35 is more aerodynamic than the 335i.

So, once the 335i is going say 120 mph it might be accelerating at a slower rate than the G37 and the G37 might begin to "catch up".
But it won't matter as the 335i will have a several car length lead at that point. The G37 might just slowly begin to get a bit closer, but it will still be a couple car lengths behind by the time both cars reach their governed top speeds (probably both 150 or 155 mph).

Time to speed & time to distance are 2 totally different concepts.

[Terry335]

We talking a stock 335 or a 335 with $60 in mods?

[jjlawyer]

The guy posts an interesting question about the physics of acceleration concerning specific motor trend numbers and everyone turns it into another G v 335 war.

The two relevant points are:

1. When the 335 is at the 1/4 mile mark, its going 104 while the G is probably going less than 100. If you were in that G, you would see the 335 moving away from you at 5 or 6 mph at least.

2. The reason that the G is only .3 seconds away at the 1/4 mark is not because its catching up, but because its only had to get to 101 mph in that amount of time, while the 335 had to get to 104 mph. By the time the G crosses the 1/4 mark (at 14 seconds), the 335 is probably going 107 mph or more. It could take more than a second for the G to go from 101 to 107. Because of the speed advantage the 335 has at the 1/4 mark, it probably made it to 107 1.3 seconds ahead of the G.

The OP should tell his friend he is an idiot.

Yes, exactly. If the slower car is "catching up" at the end of the quarter it would have a higher MPH and a longer ET.

[sflgator]

It's really quite simple...

The G37 on paper has more HP (but less TQ) than the 335i. However, in real-world tests, the G37 and the 335i are closer in HP than on paper, but the 335i has much more TQ and it's lighter than the G37. This is why the 335i is faster and would continue to be faster than the G37, even after the 1/4 mi. all the way up to the speed limiter.

very good point.
