• 2015 BMW F82 M4 vs. 2014 Porsche 991 Carrera EVO track battle comparison

      We already saw this comparison earlier in the year when Car and Driver compared the F82 M4 to the Porsche 991 Carrera. In that comparison, the M4 came out on top. Let's see what happens when the Brits over at EVO get a hold of both of these cars for a track comparison. This is the big question, does the M4's power and updated chassis allow it to beat the lighter rear engined Porsche 991 Carrera around the track?


      EVO does the comparison well showing both cars lapping at the same time. This allows some of the trademark characteristics of the cars to show. Namely that the 911 has less understeer on turn in but this is the area that one traditionally has to be careful with a 911 getting back on the power exiting the apex so that oversteer does not bite you in rear end.

      The 911 handling is definitely tighter. The M4's additional mass shows as it tends to push a bit. The 911's lead built in and out of turns is made up by the M4's power. Finesse versus muscle is what we witness. The tighter the course gets, the more it ends up favoring the 991.

      Laptimes (for reference a 458 Speciale laps this track in 1:14.2):

      Porsche 991 Carrera: 1:17.8
      BMW F82 M4: 1:19.2

      The 911 in this comparison proves it is the better sports car. To open up a gap like that on the M4 even with a huge power deficit shows how impressive the 991 chassis is. If this was a 911 model with more power, it would not even be a contest.

      The M4 is more muscle car and that is the direction BMW M is headed with their street cars. If you want the cheaper car with more power, the choice is the M4. If you want the better driver's car, it's the 911.

        I think he coined the phrase that almost anyone who has driven an M3 hard would say: "The rear end of the car limited the speed it could go". Porsche is odd with it's engine sitting over the rear, but it seems like some guys just love it - and most people can simply squeeze more out.

        I think you're absolutely right. From a performance perspective, the 911 is superior. But then, again, there's more to life than performance (I can't believe I just wrote that). What I meant was, with the things you can change and stay way under what you spend for the 911.

        I always try to explain this to a girl if I've had too much whiskey.

        No doubt. But the 911 isn't a value and that actually is part of the appeal.

        shocked the M5/6 are quicker than the M4... would think the added weight would hamper them even more?
