Couple of comments:

1.) I can't stand these guys. Watch their other videos and you'll see what I mean. They can't drive, make constant inaccurate statements, and are incredibly annoying.

2.) As a resident of Colorado, this isn't particularly surprising, nor impressive. The IS-F is very heavy and naturally aspirated and thus makes far less power at altitude than it makes at sea level. The M235i is of course turbocharged and lighter. As a result, it loses very little power compared to the IS-F at altitude. This is why if you spend any time at all living in high altitude areas and you're a car enthusiast, you're usually biased towards forced induction cars. That's why bone stock 335i's can keep up with "faster" NA cars up here in CO. Hell, I had a MkV GTI with nothing but an APR stage 1 tune that would run with much faster NA cars stoplight to stoplight simply because my car was light, torquey, and didn't lose much power at altitude.

Bad testing

These guys are terrible to watch. I love the m235i but the test is flawed. First the ISF isn't in sport mode. They are at altitude. And the race didn't seem long enough for the ISF to stretch its legs.

I looked hard at the oil filter housing and could my see the added oiler cooler lines. Makes me worry about limping this one just like the other N55 and N54 motors without the secondary oil cooler under the front right fender .

I can see thrashing or maybe even thumping but throbbing? Was he excited to lose or something?

Yes, exactly! What is it with all these M235i tests in high altitudes (same with that Willow Springs time). I have datalogged extensively with the BT tool and by the M3's own internal dyno calculations (actual moment in nm of tq), 800 ft vs sea level elevation logging has at least a -10 hp impact at redline, and its very consistent. Try this test where I live and you will likely see a different result (though the M235i is an impressive vehicle!).

In all their videos, they appear to be outside of town, which usually means an increase in elevation when you're in the Denver/Boulder area. HP loss at these altitudes is horrible. Fortunately, we can do the math:

loss = (415 HP x 5,430 ft x 0.03)/1,000

By that equation (which I found online), you're looking at around 68 HP loss for the IS-F, knocking it down to the 345 HP range, instead of the sea level 416 HP. Edmunds lists the curb weight for the IS-F at over 3700 lbs. The M235i is about 200 lbs lighter, and has a turbocharger, which all but negates the loss due to altitude. Not to mention, the M235i is only a couple of tenths behind even at sea level because the turbocharged engine has a fatter power curve in the lower RPM range.

Add all this up and the IS-F never stood a chance at that altitude.

Every time I see an IS-F, I think why? Should have just got a M3. Not impressed with them at all.

That's it exactly, so if you live in the mountains, get a turbo.

As a resident of Colorado, you are one of the few who understand that normally aspirated vehicles are strangled at altitudes like Denver and Johannesburg (6000ft+). My 135i, as well as any other 335i's are faster in Johannesburg than my M3. It has nothing to do with the Lexus transmission, but more to do with the fact that turbocharged cars lose less power in thin air, when compared to an aspirated one. The outcome would be different if the very same race took place at sea level.

Since there is not much between an ISF and an M3, how do you suppose an M3 would fare against the M235i at altitude?

M3 vs ISF at , or M235i vs a45 Amg, at altitude would be a fair comparison.

IS-Fs are actually VERY quick. I wonder if altitude was a factor since I'd expect it to pull on the top end
