Diesel Power 2009 BMW 335d @ 2008 Detroit Auto Show

http://www.edmunds.com/insideline/autoshows/detroit/2008/2009bmw335d.html

In case you haven't noticed, German's carmakers aren't big on the idea of hybrids. Sure, BMW and Mercedes-Benz collaborated with GM on the two-mode hybrid transmission, but what they would really like to sell you is a car like the 2009 BMW 335d. Yes, that "d" stands for diesel and although BMW already sells several diesel models in Europe, only now has emissions technology advanced enough to get the EPA's seal of approval in all 50 states.

I'm still loving my jetta diesel.

[AJG77777]

I own one and I love it when i said not in Cal i meant that diesel is cheaper than gas and car can go 600 miles on one tank on highway. LOVE the torque too.

[soton000]

Got 730D E65 230hp 500Nm of torque ,when raced 328i he could not shake off and when we hit 65 mph he left behind , my weight was over 2 tonnes and his half of it , i reved till 4,5k rpm he reved to 8 k rpm( his engine almost fell apart) well torques does it all no doubt

[bekomach]

In conclusion, if gasoline has a bit greater HP and the torque difference is not much (smaller than ~100-120N.m) then gasoline generally takes the diesel.

[bekomach]

I'm giving another example;

BMW 5.30d = 231 HP 500N.m torque

BMW 5.30i= 231HP 275N.m torque

5.30d is better on all acceleration test,

if you take new 5.30i 272HP with 300N.m torque 0-100is better than 5.30d but acceleration from 60kph, or 80kph or whatever due to 500torque 5.30d is quick ok?

However if you draw torque, HP, RPM curves yes you'll see that gasoline uses their max torque wide range of RPM.

@bekomach i just wanna know one thing is that torque or horsepower is ACTUALLY more important during acceleration cuz i keep ppl hearing that ppl say diesel will be quicker cause it have a greater torque BUT gasoline have much more HP and RPM so idk who or what to believe..........:(( not talking about top speed thou. just acceleration

[bekomach]

There are several things affecting the performance of motor and the acceleration:

1-HP of engine

2-Torque

3-Gearbox ratio

4-Equipment and all materials used in production

5-ECU, chip tuning etc

6-Sequence of cyiinders ( V, boxer, in-line, wankel)

7-Weight of car

As a matter of fact, prediction of acceleration is not easy, but generally if there are cars with 200HP (one of gas, one of diesel), always diesel has a greater compression ratio, means greater torque, so diesel is good :)

[bekomach]

I don't know about trucks, but, nearly all diesel car or bus or truck has a turbo unit to increase performance.

Diesel has lower top speed because it reaches maximum of 5000-5500rpm but gasoline cars can reach even 8500-9000rpm, if there are two cars with a same gearbox, of course gasoline has a higher top speed, do you understand?

[7150285]

@bekomach another thing that i wanna know is that but diesel pickup truck have extremely fast acceleration even from 0-whatever but not a very high top speed thou......i heard they uses boost launch or something like that??

[bekomach]

@7150285 When you are starting from zero kph, yes gasoline will a bit faster and can reach the maximum speed (for example 250km/h) earlier, but if you start from 80km/h or 120km/h, torque of a car more effective instead of the horsepower. 3.35d has 580N.m torque, 3.35i has 400N.m,

180N.m torque is a great number so 3.35d has a greater acceleration except from starting 0

Please check 3.35d and 3.35i technical details. For ex:

335i: 80-120: 5.2 sec

3.30d 80-120: 4.7sec

3.35d 80-120: 4.0sec

[7150285]

@AJG77777 but the acceleration is slower right?

[7150285]

@bekomach i thought diesel will have a slower acceleration instead??
