• Australia's most powerful production car takes on the CLA45 AMG - Holden HSV GTS versus CLA45 AMG drag race

      Interesting comparison here between the most powerful production car Australia has to offer, the Holden HSV GTS with 577 horsepower, versus the new CLA45 AMG. On paper this is quite the mismatch as the CLA45 AMG M133 turbocharged 2.0 liter four-cylinder motor has 'only' 355 horsepower. However, BenzBoost readers will know that the M133 AMG motor is slightly underrated. The CLA45 AMG also weighs a substantial 709 pounds less than the Holden HSV GTS despite featuring all wheel drive and a dual clutch transmission.


      The HSV GTS is more traditional muscle car with rear wheel drive and a big V8. The engine is borrowed from the Camaro ZL1 so it is the same supercharged 6.2 liter LSA V8 we all know and love. The Holden does not have a fancy dual clutch but a 6-speed automatic.

      American raw muscle versus German engineering, what wins? Well the more powerful car but it's closer than HSV GTS owners would like it to be. The CLA45 AMG is running high 12's at close to 110 miles per hour. That is impressive.

      For as much power as it has and the size of the motor in the HSV GTS, a 12.1@118 is almost a letdown. The CLA45 AMG definitely is poised to be a giant a killer especially once the aftermarket for it heats up.

        And heres a S200 making 410 whp with a F20c and anybody who knows honda knows that F series motors are $#@!.

        K20 or K24s is where it is at!

        http://www.evans-tuning.com/dynos/20...-k-pro-tuning/

        Then last but not least here's a bone stock s2000 CR with a F22 running 718 whp off Q16 gas!

        http://www.evans-tuning.com/dynos/20...onda-flashpro/

        that is a .2 displacement difference on those two cars and race gas.

        With that being said I think that CLA 2.0 Can do wonders with proper aftermarket support.

        and its a awd platform so it will hook up unlike most hondas FWD. The s2000 is RWD so it makes a lot of honda tunners very happy let alone they make a conversion kit to drop in a k series motor and really make a monster!

        And I can post my 415whp graph with my 2.0 too and all the other evos with 800whp on built motors and stupid huge turbos!!! That's not the point man. I'm talking about the car with the stock turbo all stock just FBO and tuned. Maybe I should bolt and underline stock? Stock

It has a nice amount of lag man. If you want me to post up my dyno graph of my k04 or my EFR on my cobalt, you'll see it's really close to the way that spools.
        Pretty nice graph considering this output if you ask me. Especially the torque curve:

        It's a direct injected motor with low compression. Sure, that's a large amount of factory boost but at one time people said you couldn't do higher than 11.0:1 compression on pump gas and then BMW comes along with several motors doing that.

        I'm not saying there's a ton of power in it but there is power in it.

        For now, we just gotta sit on the bench and see where it goes.

        No I'm confident in saying there's more power there than the factory gave us. The question is how much.

        I'll stick with my theory of not more than 30-40 whp FBO and tuned maybe 50whp at most if its on racegas lol.

        That's enough for the car to get close to the 11's. That's impressive.

        If it's an AMG, I'd expect it to. LOL

        Well the C55 AMG never did with just bolt ons and that was a big V8. Times are changing!

        I never saw an intelligent debate about four cylinder power potential in any Fast and the Furious movie although I have not seen the most recent one.

        for me its still 4 cylinders, compact, sporty and produce 355-hp!! maybe price wise it wont be perfect deal in the US but for EU content definitely will shine. Moreover there is always room for development such as tune, DP and other support mods that will make baby AMG hit 11's maybe less Click here to enlarge

        Kudos to AMG for raising the bar! This forces BMW and Audi to compete in this segment and more importantly, bring those cars to the USA.

        The CLA45 is a great car. I also believe FBO's and a tune will net 50-70whp, which will be enough to wreck some quick cars out there. Time will tell how the motor holds up beyond that.

        On a 2.0!! That wont hit full boost till around 5.5-6k rpm. You of all people should know that LOL

        The turbo stock comes with 26 psi. With a tune and FBO how much more do you really think it can gain. Really 50-70whp?

        I think it'll only peak 30-40rwhp put pick up tons of power under the curve. Enough to challenge the likes of a C7 or C6 LS3, C63, stroked M3, Boss 302, FBO B8 S4, or Z28 down the 1320 (in terms of E.T). Mainly due to the AWD and stock DCT.

        Does anyone have the compressor map? This thing will be a monster with ethanol, opened up/bigger turbo and some mods to keep that water to air intercooler really cool.

        People are just thinking it is maxed out 26psi because they aren't used to it... I've seen stock 4g63s with hybrid stock turbo setups push 35psi all day on e85..

        It's all about combustion chamber temps, the clamping force of the stock head studs/gasket and the rod strength.
