335i tt naj bi imel precej več konj kot je deklarirano - plus navor - na nekaterih testih je bil celo precej hitrejši - in to avtomatik - od stare M3 in praktično enak novi RS4. S tem se precej ukvarjajo v tem testu (in še marsikje, praktično vsi so opazili, da je turbo povsem primerljiv oz močnejši od stare M3, verjetno ne samo zaradi navora)

The data doesn't make any sense. We're tearing our collective hair out trying to determine why the track-test numbers from our 2007 BMW 335i test car are so far off.
Our freshly minted 3 Series twin-turbo coupe has not only eclipsed BMW's own impressive performance figures — by a ton — it's also smoked those of the 2005 BMW M3 Competition Package, a car we called "The Best M3 Ever Sold in America." And while that admittedly turbo-deprived car had been a six-speed manual, the Arctic Metallic 2007 BMW 335i Coupe cooling in the driveway is but an automatic. Nothing about our Austrian First Drive of the car prepared us for this.
More than half fast
Consider the facts: This 2007 BMW 335i test car blazed from zero to 60 in 4.8 seconds. BMW says the new coupe mit twin-turbo engine and Steptronic six-speed autobox should make that trip in 5.5 seconds. Seven-tenths of a second quicker? That's 13-percent better than BMW's claim. Folks give aftermarket tuners wads of cash for that kind of performance bump, especially when a car starts out in the mid 5s to begin with.
Our 335i similarly scalded the quarter-mile in 13.3 seconds at 105.9 mph. For comparison, our 2005 M3 Competition Package used up 5.5 seconds getting to 60 and finished the quarter-mile in 13.7 seconds at 105.4 mph — close, but still a rearview-mirror performance. We almost beat the all-powerful 2007 Audi RS4, too. Despite a 120-horsepower advantage and all-wheel-drive launch superiority, it just nicked our 335i's 0-60 and quarter-mile times by a paltry 0.1 second each.
