Also, a car wouldn’t be able to fill the garage with exhaust gas at a constant rate. As oxygen is consumed and replaced, there is less oxygen available for combustion. Because of this, less exhaust gas can be produced, and the cycle repeats. If the only way to die was because of oxygen deprivation (not carbon monoxide…

You asked for corrections so I’ll add one:

Good guy BMW driver? Parked so 3 cars could fit into 2 spots when parking was limited

I would imagine the spikes were at least 50-100 yards in front of the trucks blocking the road

Today’s country music is formulaic and pandering???

With particle number regulations expected to be put into place soon, I would expect to see GPFs become very common.

100% agreed.I started looking at some used ATS’s with the 3.6L but that center stack was a dealbreaker for me. Looking at a Jaaaaaaag XF now :)

Sure boost pressure doesn’t give you the volume of air, but volume is related to temperature and pressure by the ideal gas law. Unless one compressor is much less efficient and heats up the air significantly more, then the volume output at a given boost pressure will be very similar.

Totally agreed. 10 hp per lb of boost is a good rule of thumb, so 5 lbs adding 125 hp just doesn’t add up to me. Throw in concerns about the IMS bearing and it’s a CP for me

I think the issue is that it’s hard to find non-recognizable cars that only look 5-10 years old for films like these. Since there’s not much interest in cars like these, not many of them exist any more, or at least not many that aren’t rusted out heaps of junk. Most of the period correct cars that still exist are…

Good point. It’s likely programmed to take that specific route, but all other functions are done autonomously

True, I tried watching the video again too see if there was a lane change or something that would better suggest which of the two it is, but there was nothing that stood out to me.

Have you considered that the autonomous software may be generating that line?

Velocity and acceleration are two very different things

Haha, I guess I should have added that for the same contact patch area, a taller tire provides better longitudinal acceleration than a wider tire

The confusion is because g-force is a bit of a misnomer. 1 g isn’t a force at all, but an acceleration. Standing still, the force pushing upwards on the soles of your feet is equal to your mass multiplied by the acceleration from gravity (1 g). That gives us the familiar equation F=m*a. If you’re sitting stationary,…

You will have more friction force, but also more mass to accelerate...because of the nonlinear mu that tires have, acceleration is actually reduced by increasing mass.

I know it’s being pedantic, but you can accelerate faster than mu if you include downforce in the equation. Most cars are power limited, rather than traction limited, once downforce starts to become significant, but a sufficiently powerful car could take advantage of the increased friction force.

For longitudinal acceleration, a taller tire typically works better than a wider tire. Wide tires help lateral acceleration.

Yeah, but CG and drag coefficient are independent quantities. In automobiles, they are usually related, but they don’t have to be. Also, in the argument above, point #7 takes aerodynamics into account.
