    Default POWER to WEIGHT ratio ...... in some new cars Mazda 3 Turbo AWD & others

    TBH ...
    It is all about power to weight ratio ... 0-100kph , 30-100 and 100-0 .
    Change the HP or drop your cars weight and center of gravity , changes how your car handles.
    Some of you love the extra HP off the line. More is better. Keeping that speed around corners is better. But how fast can you stop that speed.
    I love keeping all that speed and then stopping 40 feet shorter. Think about better pads on those oem rotors or going bigger rotors next time you have change your pads.
    Alot of after market oem fitting pads with more grip/stopping power. For daily drivers, Street & some track, and autocross enthusiast. Hawks/EBC/G-loc and others..do your research.

    As for power to weight ratio ... yes 250-300 HP on a 2000 lbs car is that ideal street car and especially fast too. A car 2000lbs and 250 HP would be .125 hp per
    pound (HP divided by weight). Keep in mind , weight affects braking and cornering performance, but you guys already know that

    Here are some cars out there that i would like to compare to the new Mazda 3 Turbo AWD:

    Golf R 288 HP 3300 lbs ..... Power to weight ratio : .087 hp per pound
    WRX 268 hp 3300 lbs ...... .081
    BMW 2 series 248hp 3380 lbs ...... .073
    Honda Type R 306 hp 3106 lbs ..... .098
    2021 Mazda 3 Turbo AWD 227hp 3400lbs ...... .067 (canadian specs)
    Mazda MX5 181 hp 2348 lbs .... .077
    Alfa 4C 237 hp 2400 lbs .... .095
    BMW M2 Comp 405hp 3700 lbs .... .109
    Porsche GT4 414 hp 3200 lbs ... .129
    370Z 332 hp 3300 lbs ..... .100
    SRT Hellcat 717 hp 4509lbs .... .159
    Shelby GT500 525hp 3800 lbs .... .138
    Porsche GT3 RS 520 hp 3153 lbs .... .165

    Hmmmm so why is the MX5 always the fastest at all my autocross events.....

    In my 2012 GX im at 2600 lbs and 170whp (approx 220 hp) ... .085
    (I have not weighted it without spare / jack / jack accessoroes/ extra lug nuts/ oem battery/ plus other dib and do das in the glove box and hiding = almost 100 lbs)
    Hoping to drop more weight and add 20+whp after i rebuild and aiming at +8K rpm. I would love to get it close to .100
