Also note that MT said they had no problems with this car on canyon roads and the xdrive does not feel nose heavy like the rwd.

Another thing to consider.
We might not be seeing the full potential of the PPK yet. This is the first test of the Xdrive 335 F30 period. We have already seen 4.6/13.3 at 105.5mph from a RWD 335. So 4.4/13.0 at 105.4 is largely the traction of Xdrive, the fact that the trap speed may only be equal to a NON PPK RWD car-well we might see interesting numbers from a PPK RWD car. 4.4/12.9 at 106+ maybe. That would be neat to see.

Two things: MT tested their 335i at 13.3@103.4 mph. the test you are referring to was a C&d test. different driver different tracks so i would not draw any conclusions from comparing these two tests, especially as it relates to trap speeds. Second, note that the rwd you are referring to was wearing staggered summer 19s. There is a lot of time left on the table for both rwd and xdrive. Either way this is exciting news for PPK I agree with you, both could easily be trapping 106mph with the right tires. Lots of potential here.

But in the end, I agree and we will hopefully see more testing of PPK equipped cars-I am hoping in varieties such as RWD and or 6mt.

But it did not say xxx.x for any car in the CD test with the IS350 and ATS, they did not include the fraction as they did in the PPK testing via MotorTrend.

We all think we remember stuff well at times. I once thought I read that the msport 4 series would come standard with adaptive dampers.lol. Big mistake Edit: MT's rwd did the 1/4 @103.9mph not 103.4 as i had noted so fuzzy memory is not working for us today, lol.

I really do not care to get into a debate about the findings of American mags. I have already talked at length about them and it is well documented. The concerns about the steering is bullshit that is just American mags whining over EPS because they want to be "traditionalists!" because we all know hydraulic power steering is the enthusiast performance oriented steering of choice... Despite the fact that Professional Race car drivers will rather deal with driver fatigue due to manual steering then allow their engineers to put a power steering unit in. When Carlos Lago actually has a racing resume I will listen to what he has to say but seeing how he was just some kid with good writing skills that sometimes tracked his parents car.... I don't give a fuck what he or Lieberman or the Editors of C&D say. However, I think the big issue is when you compare the 328i to the 335i. The real issue I see when driving the 335i is that you can feel the weight in the nose. As for the "softer suspension" fuck that noise.. that is just bullshit statement. The only concern I ever felt when blasting down VIR with the new 335i is at higher speeds the nose does not turn in as crisp or as accurate as the 328i. Having said that the tires on my 328i is the Pirelli summer tires and they do not respond fast enough to steering input as the Bridgestone Potenza runflats on the 335i. A lot of people do not realize that the rubber on the wheels massively effects the way your car drives. I cannot wait to get some Bridgestone Pole Positions to so I can really see what the car can do. |

the PPK adds more torque to the 8AT model than it does the 6MT. So while on a non-PPK model you could argue that a manual with no torque converter has less drivetrain loss than the auto** and therefore more "power", I would argue that the extra torque on a 8AT PPK vs a 6MT PPK makes up for any torque converter penalty. **although I will say MFGR's across the board have spent a great deal of engineering in closing this gap significantly. Torque converters are not the power sucks they were 10 years ago. |

the reason BMW sent an XDrive to MT for this test is to show off the best possible 0-60 numbers. rwd would have been somewhere around 4.6s-4.7s and that would not have been a very good show case for the MPPK.

For trap, you are measuring your average speed across a certain distance. Average and max are not the same. But don't take my word for it This is a direct quote from the NHRA website, in the section entitled "The basics of drag racing:" Speed is measured in a 66-foot "speed trap" that ends at the finish line. Each lane is timed independently. |

not sure on the actual weight. Once you throw in the flywheel and clutch, I am not sure how much weight savings you're actually getting. You might be better off skipping breakfast or not wearing socks

a 1/4 mile pass is 1320 ft. It takes you time to go from 0 to crossing that marker at 1320 ft. The time, that is referred to as your ET or ELAPSED TIME. When you cross that line and register the ET, the speed you are traveling when you register it is your TRAP SPEED. Power to the wheels, is the power that makes it to the ground after all the losses associates with a drivetrain like transmission, axles etc. A torque converter found in an automatic transmission saps a small amount of power more than a manual transmission. This allow for more power to reach the ground. More power to the ground is best represented by trap speeds, not necessarily by ET. ET and 0-60 is very traction dependent. Example: High powered front wheel drive cars. I grew up on them. They are very difficult to launch and so I had terrible 0-60 times but could plant the power at higher speeds, making for roll on races or races from a high speed rolling start. A cars roll on prowess is better indicated by trap speed. So my FWD car might do 0-60 in 6.0 seconds, ET 14.2 but Trap at 105mph My RWD car might do 0-60 in 5.4 seconds, ET 14.2 but trap at 100mph. So racing, well if I was in the RWD car I would want to race the FWD from a dead stop where I have the advantage. If I am in the FWD car, I ask to race from a "roll", maybe 30-100. Make sense?
