    Adobe?

    Didn't they build houses out of that stuff in Mexico/Arizona before it became the name of a programme?
    Excuse my ignorance of the branding. What company? I've never heard of this make.


    Sadly, I believe there was only one to ever roll off the assembly line. My favorite part of the car was its ability to be reshaped by hand after fender benders.

    Ahh - but so practical yes? Fantastic. But it would have put the bodyshops out of business hence the reason for it's eventual production demise.

    The SLK 350 has 32.9% more power than the new MX5, and 38.39% more torque. That means it will be about 38% faster down low, and 32% faster up high. A whole third more power and torque is quite a lot though, it's just not the twice as much as it seems on when quoting figures in a void. Torque is all well and good but you need to know how much weight that torque is trying to move. A vehicle with 3000nm and 2000kw that is 10 tonnes is going to be the same speed as a vehicle that has 300nm, 200kw and is 1 tonne.

    High torque can feel a lot faster than low Torque, despite being the same speed. I know a lot of 5.0ltr Commodore owners who feel their cars are much faster than my 1.8ltr Honda Integra, and are unhappy when they find out that in fact my Integra can keep up, and in many cases go faster.

    Just to show the difference, here are the two cars 0-100km/h times (0-60mph):

    Mx 5: 7.10 s
    SLK 350: 5.60 s

    So the Mercedes is actually quite a bit faster.

    As for your rotors, 14" is 355mm (I have actually seen elsewhere the rotor size being voted at 330mm, but I'll trust you on this one), which is impressive but the MX5 has 290mm rotors on the front. That means your rotors are only 22% larger, while your car is 35% heavier, which means just based on that your car wont have the same stopping power as an MX5.
    Your front tyres (which are the primary tyre used in braking) are 225mm wide compared to 205mm for the MX5, meaning your tyres are only 10% larger. The rears are more impressive at 245mm, or 20% larger. Again however, your car is 35% heavier, so your loosing out again.
    Having said that, the better materials and I dare say better engineering that went into your suspension and brakes would improve stopping power. But from what I've found on the interwebs (cursory search, feel free to find contradicting reports) the MX5 beats the SLK in stopping distance.

    SLK 350 60-0mph: 126ft
    MX5 60-0mph: 113ft

    You're right, the SLK is in a different class. It's a more powerful GT car, and less of a low power handles-like-it's-on-rails racer. I actually quite like them and would consider taking one over an MX5 so I by no means think you made a bad choice, it just seemed you were implying that the MX5 was crap compared to the SLK 350, which it isn't.

    Ultimately if you enjoy driving it that's the main thing.

    First, I enjoyed reading your post - some well though out points that you obviously put some time into. However, your numbers are way off, not sure where you're getting them, but the real numbers are below.

    The SLK 350 has 32.9% more power than the new MX5, and 38.39% more torque. That means it will be about 38% faster down low, and 32% faster up high. A whole third more power and torque is quite a lot though, it's just not the twice as much as it seems on when quoting figures in a void. Torque is all well and good but you need to know how much weight that torque is trying to move. A vehicle with 3000nm and 2000kw that is 10 tonnes is going to be the same speed as a vehicle that has 300nm, 200kw and is 1 tonne.

    High torque can feel a lot faster than low Torque, despite being the same speed. I know a lot of 5.0ltr Commodore owners who feel their cars are much faster than my 1.8ltr Honda Integra, and are unhappy when they find out that in fact my Integra can keep up, and in many cases go faster.

    Just to show the difference, here are the two cars 0-100km/h times (0-60mph):

    Mx 5: 7.10 s
    SLK 350: 5.60 s

    So the Mercedes is actually quite a bit faster.


    Actually, your numbers are seriously off.
    MX5 Specs
    SLK350 Specs

    Here are the real figures:

    SLK350 curb weight: 3318 lbs
    SLK350 horsepower: 305hp
    SLK350 torque: 265 ft-lbs
    SLK350 EPA est: 19/26mpg
    SLK350 0-60 time: 5.3 secs
    (SLK350 0-60 time and horsepower ratings pulled from the model review by edmunds, which is more accurate than their spec page, and which match the info listed in my MB manual: 2009 SLK First Drive)

    SLK350 horses-per-pound: 0.0919 hp
    SLK350 torque-per-pound: 0.0798 ft-lb


    MX-5 curb weight: 2602 lbs
    MX-5 horsepower: 158hp
    MX-5 torque: 140 ft-lbs
    MX-5 EPA est: 20/27mpg
    MX-5 0-60 time: 7.5 secs
    (MX-5 0-60 time pulled from the edmunds model review: MX5 Model Review)

    MX-5 horses-per-pound: 0.0607 hp
    MX-5 torque-per-pound: 0.0538 ft-lb


    As you can see here, in reality, the SLK350 is much more powerful than the Miata, to the point that they can't even be considered in the same class of vehicle. And this would make sense, since you will never see them racing in the same bracket in track racing, autocross, etc. The 2.2sec difference on the 0-60 times alone speaks pretty well for itself.

    And trust me, get into an SLK350, take her for a spin and you will see that there is seriously no comparison between these two cars, performance-wise. To top it off, the fuel mileage is literally about 1mpg different between the two cars. I've since added Green Air Filters to my SLK, which increase my mileage about 2mpg in mixed driving on average, so I'm now getting better fuel mileage than a stock Miata.

    It's not fair to compare the two cars, though. It's like comparing the Cayman S to the Mazdaspeed 3. They're not in the same class at all, and doing so unfairly makes the MS3 look like a crappy car. Same with the SLK350 vs Miata.

    My only point earlier was that anyone who would say the SLK is "Miata-ish" or "girly" is seriously ignorant, to the point of absurdity. When I hear such things, I start hearing the Deliverance theme song in the back of my head, and I just giggle. Whatever, let the rednecks be rednecks, that's my motto.


    You're right, the SLK is in a different class. It's a more powerful GT car, and less of a low power handles-like-it's-on-rails racer. I actually quite like them and would consider taking one over an MX5 so I by no means think you made a bad choice, it just seemed you were implying that the MX5 was crap compared to the SLK 350, which it isn't. Ultimately if you enjoy driving it that's the main thing.

    A stock SLK350 is built with luxury in mind, and lacks the "handles-like-its-on-rails" characteristics of the AMG sports package, which I have added. This includes much stiffer sports suspension, lowers the car by about 1 inch, adds larger tires and brakes, etc. While I can't speak for a stock SLK350, because I don't own one, I can definitely say for sure that my car with the sports package handles like it's on rails. It's not a Lotus, for sure, but I'd say the handling is just slightly softer than that of the Cayman S, with similar turning characteristics, which impressed the hell out of me when driving it. There are very few cars on the road with similar abilities. I've also added the Kleeman headers and x-pipe setup, so I'm probably seeing about 10-20 more hp than a stock SLK350.

    Definitely not saying the Miata is crap, however. I really enjoyed the ride when I test-drove it, and was surprised at how peppy it felt. The handling in that car was pretty excellent, which is to be expected. However, the MX5 feels "quick" where the SLK350 feels "FAST." You can't do burnouts in a Miata, nor do you often have to worry about the rear getting happy when downshifting to 5th at 80mph. Also, the cabin in the MX5 is quite loud with the top up or down. If price is a concern, the Miata is a great car. It's worth noting that you can pick up 2 slightly-used (as in, one year old) Miatas for the price of a single SLK350. I just felt that for overall thrills, the SLK fit my needs better and I was willing to pay the additional costs. Again though, I think the Miata is a great car and personally think people who put it down are just ignorant. And when I hear people call them "girly" or "gay" cars, I just think those people are either douchebags or just closeted homos (either way, they suffer serious insecurity issues and obviously doubt their own manhood).

    So what's the lease rates on a black, power hard top, SLK350? Has to be pretty cheap.

    You think folks driving Bentleys stinks of new money and douchebaggery. I think that is absurd.

    I think men driving SLKs stinks of the male driver hitting for the pink team. You think that is absurd.

    That is all.

    That's because MB doesn't race SLK's, whereas there is a SCCA class that does actually race MX-5's. When I think MB, the only cars I feel might be track or race worthy is the Black edition AMG CLK's. The SLK, along with it's bigger brother (SL) was built to be more of a luxury blvd cruiser.

    The CLK Black is a serious car.

    I also think homophobia is a clear sign of a douchebag (the type of distasteful ignorance our society has been working hard to remove for the last 40 years or so). Or maybe I'm wrong in concluding that you find homosexuality to be a character flaw. Maybe you were calling me a homosexual as a compliment.

    Or perhaps you are just a 19-year-old frat kid who hasn't matured enough to learn that calling someone a homo as an insult proves only that you are an ignorant dipsh!t. Perhaps next time you'll be calling someone a "darkie" for liking watermelon. Perhaps you could impart some other bigoted witticisms for us and further prove your total lack of an education, and immaturity.
