The stock fist engine, stock from the throttle body to the oil pan has made 423whp with BPU and a bolt on turbo upgrade... And its 2700#.
I will concede the mini-coppers new engine make it a much more attractive car. Mostly because I believe its basically bmw's awesome N20-series motor that makes almost 300whp with just a tune and E85 in the other bmw cars ( I know this because I cross shopped a bmw X1 to the fist ). The issue with the mini, and it being more of a focus ST competitor ( aka, "punching above the fist weight" ) lies in its price. A base fist is $21,400 ( or so ). Show me a 8miles off the truck mini cooper S that doesn't say $28k-$30k next to it, or MUCH MUCH more if you start adding bmw options ( which can add up to more than the cost of 1/2 of a new fist actually ). Lets not even touch on the fact your not going to
Get special financing on a new
2016 mini cooper S or get the awesome rebates ford has. So comparing a $21k car to a $30k car does sort of make a difference when your spitting hairs like we do in the hot hatch segment. I am excited for the mini forks, it only took just short of 15 years to get them a real driveline, and it came with another 400lbs in weight over the OG supercharged models.
I have less than $2,000 in my entire build. I went 13.3@104+mph on $76 a piece street tires on a 233whp tune. I can make around 284whp with reasonable weather and unless I told you any different at all, I could say, "its a stock fiesta with an air intake, cheap exhaust, and china intercooler" (all true btw). I'd like my chances against a 2010 mustang from any kind of roll right now ( unless its a power adder car, let's be real ).
Like the OP said, it punches way above its weight. We are actually all sitting here talking about a crappy ford fiesta facing V8 rwd muscle cars, $30k german useless mini's, and having a 12sec capable car that could be modded for less than $2,000 that also retains good fuel mileage, good insurance rates, reliability, and the best part? Almost no one gives a crap about its straight line speed, owners mostly love it for its drive. I mean, jeezzz, I'm out there racing new audi S4's in a fiesta !! Lol.
Name anything that is in the $21k area that competes with the fist? Pretty sure most people would agree the mini/fost/gti are all in a higher class. Lets just say I haven't lost any sleep about what's happened ANYTIME I've ever lined up against any of those 3. Even though I'd like my chances against a normal caymen, gosh... I don't think I could let a caymen S go for a fist. Or a BMW 135i coupe.
