Mythbusters: Cars vs. motorcycles

[Urano]

haven't seen the mythbusters episode, but i remember to have read a french study, some time ago, that reported as bikes "emit" more pollution but at the end of the day are less harmful.
this seems to be caused by the fact that the smaller medium displacement is paired with the shorter medium time the bike engine is on than the car's on a city trip.
bikes suffer so less from traffic jams and do not usually have to go around searching for parking. they concluded that despite the higher emissions, bikes are anyway better for city pollution.

i believe it will be controversial for long...

a link for the mb episode?

Because as I keep prattling on about, a car exhaust system has far more volume into whihc you can shove scrubbers, as well as revving MUCH lower, thereby producing far more harmful pollutants over time and distance. I'm glad they did it. Maybe you fuckers might start to look at the links and shit I post, eh?

So does that mean you agree with their findings that bikes are more feul efficient?

If you've got some links with info about the relative harm of the different pollutants emitted I'd be interested.

You can tell just from the smell produced by motorcycles that pollutants are high. It's the same as lawnmowers put out more pollutants than an SUV/min.

I don't quite understand how 18L of fuel can produce more pollutants through my bike than my car.. does't that just mean my bike's more efficient and detonating the fuel more???

No I don't because, they didn't take 1000cc sportsbikes on a typical Wairarapa ride. I've seen Ducati 996s looking for petrol stations around the 70-80kms traveled mark. As I've always maintained, testing for fuel efficiency is very different to measuring actual use.

[Gremlin]

you dont get 180+ hp out of 998cc by being nice to trees.

Well, they're not made out of trees are they?

Maybe you fuckers might start to look at the links and shit I post, eh?

mmmmm....




nope

Cars can be thrashed too, fuel efficiency must be measured under the same conditions, your argument is that more motorcycle riders waste fuel than car drivers (though I'm yet to see a biker pour deisel on the road). I don't beleive the fuel wasted is more than the savings, but in either case, it is not something that should be taken into account when comparing mechanical fuel efficiency as it is a user choice, and not inherent in the mode of transport.

I think Triumph conrods are.

I would argue that when comparing 'like with like', bikes are considerably less harmful to the environment.

If you are comparing a 'Green Party voting Hybrid driver' with Mr Gixxer on P, then you come to such contrary mythbusting conclusions.

If you compare a new Ducati 1198 with a new a new Ferrari V12, with both driving as hard as, I suspect that the myth would be confirmed.

The same goes for Mr Standard 1400cc car commuter, compared with Mr Standard 250cc motorcycle commuter

Well from the way it was written, it sounds to me like they are comparing a car and a bike on a commute, so they may also be able to take into account the decreased travel time due to being able to lane split etc

HAven't seen it but it's fucking hard to compare apples with apples. For example.

A Scorpio or an R15 uses a shitload less fuel than my wifes Legnum. Unless the Legnum's carrying three or more people, then you need two bikes minimum and things even up a little. The cars tyres last a hell of a lot longer and it's service intervals are longer, although it needs four times as much oil every service.

If you compare an R1 with the Legnum, it consumes tyres 4 times as quickly and has slightly worse Km/L of 98 unless you ride like a total fucken Nana.

Hopefully they even the stakes up a bit and compare the 180hp bikes to the 1100hp cars........

Looks like they are getting a lot of feed back on the tests. They only tested emissions and considering they both drive hybrids this focus is no surprise. Should be an interesting watch.

[James Deuce]

Nope.

That's alright because I won't be buying bikes off you. Kind of sick of your sanctimonious conversion.

How about comparing a 'busa with my 1.3L Ka? I know I'll use less gas. It uses less gas than my 750 did in exactly the same usage.
