2009 Infiniti FX50 vs. 2008 BMW X5

February 10, 2009

I'm going to go out on a limb here; our long-term 2009 Infiniti FX50 is the quickest factory bone-stock SUV we've ever tested. In recent testing it hit 60 mph in 5.5 seconds (5.3 seconds with one foot of rollout like on a dragstrip) and covered the quarter mile in 13.7 at 101.5 mph. Impressive.

Around town, the Infiniti is mellowed by a sluggish throttle tip in, but lay into it and hold on. That big 5.0-liter under the hood really pulls, and it relines at a four-cylinder like 6800 rpm.

But this blog post is not about the FX50's thrust, it's about its other abilities. Which are also impressive; 60 - 0 stopping distance of 117 ft., 63.3 mph in the slalom and .82g around our skidpad. As far as SUVs go, this thing is a hot rod.

Still, I was expecting more.

It's on huge 21-inch summer tires for Pete's sake. Dunlops. SP Sport 01. 265/45R21 front and rear. That's quite a bit of contact patch. Far more rubber than our long-term BMW X5 wears. It rides on all-season Michelins. Latitudes. 255/50R19 front and rear.

Yet, the BMW nearly matches the Infiniti's dynamic performance. It stops from 60 mph in 123 ft., covers the slalom at 62.9 mph and circles the skidpad at the same .82g. Sure the FX50 smokes it in a straight line, but with more aggressive rubber the BMW would certainly stop and handle better.

Oh, you want proof. Then check out our recent road test of a 2008 BMW X6. That truck wore the optional meats. Huge all-season Dunlops. SP Sport Max. 275/40R20 front and 315/30R20 rear. And it smoked the Infiniti in every dynamic track test except acceleration. It stopped from 60 mph in just 111 ft., blasted through the slalom at 65.3 mph and circled the skidpad at .87g.

So are the Infiniti's dynamics disappointing or are the BMWs abilities so redamndiculous that this entire blog post is worthless?
