2009 Infiniti FX50 AWD: The New "Five-Oh" V8
January 14, 2009
Remember the 5-liter Mustang? I remember growing up in the mid-1980s and being impressed by the 1987 Mustang GT's then-heady output of 225 horsepower.
And hey, our long-term FX50 has a 5.0-liter V8, too. But now we have 390 horsepower, 369 pound-feet of torque and a redline close to 7,000 rpm. In a crossover SUV, no less.
Plus, the FX50 meets Bin5 (LEVII) for federal tailpipe emissions standards. On this historical EPA emissions guide, it looks like Bin5 is limited to 0.07 grams per mile for NOx tailpipe emissions and 0.01 for particulate matter. For a 1987 (Tier 0) Mustang, the emissions standards were 1.0 for NOx and 0.2 for PM. These numbers are just standards, but they give you an idea about how much cleaner cars are today.
If I owned our Infiniti FX50, I'd have to put a louder exhaust system on it, though. Not too loud, mind you, but something to bring out the V8's character a bit more. Every Joe Schlub has an aftermarket exhaust on his clapped-out Tahoe, so why not put it on something that could actually benefit from it?
