Not exactly and especially not for cars where bluff-body aerodynamics are in play. The usual purpose of a VG is to generate a flow structure that will pull higher-momentum air that is away from the vehicle surface closer to the body to energize the flow and delay or prevent flow separation. For aircraft, they are…

Take a look at his braking point for Turn 1. It’s AFTER the last marker. The margin for error between braking too much or too little must be in the hundredths of a second. Unreal.

With its’ sealed underside, expect plastics and gaskets to start failing from heat soak after the warranty expires. The oil pan gasket on my E60's N54 motor weeped to the tune of a quart of oil every 7500 miles before I replaced it at 100k miles. Having never done such a thing in all the years of owning cars, I asked…

Preach on, Brother! I’m getting fed up with systems on cars that help the manufacturer eek out a couple more MPG on the EPA tests so their CAFE numbers look good but cost way more than their benefit in fuel savings when they fail. Electric water pumps, heavier starters for stop/start, sealed underbodies for better…

And now......It’s not Patrick George’s E23, but it IS its’ drunk racing cousin....

My wife had a friend in college who was an awful driver. She’d been in 6 accidents and totaled 2 cars since getting her license. They took a trip to DC with some friends and my wife volunteered to take the first driving shift in the friends car. When she got in, she noticed that all the mirrors were way out of wack…

Quick, Sherman, to the Way-Back Machine!!!

If the car has a heads-up display, the windshield is probably polarized and unavailable as an aftermarket part. This forces the purchase of a genuine Alfa Romeo windshield which is going to cost more. The windshield of my E60 BMW 535i was $1200 because of this. No HUD and the cost drops to $400.

Meh.

There could be several things going on with this paint as there are many formulations that do different things. Traditional paint flow visualization is as several people already explained but there also exists temperature-sensitive (TSP) and pressure-sensetive paints (PSP). PSPs can also be further divided into…

What needs to be taught in Driver’s Education is a simple philosophy that would serve in many situations: “DO NOT IMPEDE THE PROGRESS OF OTHERS”. It works for lane etiquette, merging situations, keeping THAT guy from letting someone out of the parking lot who wants to cross three lanes of traffic to get to a left…

As a Howerton, I approve of this post.

Casey Kia in Newport News, VA just got one in. Saw it yesterday. The GM of the store is a neighbor. Maybe I should ask for a test drive............

By no means was he getting smoked by the 599 driver.

My friends and I were in Monterey for the BMWCCA Oktoberfest celebrating their 100 Jahre anniversary. Having just met the head of BMW Classic during the unveiling of Elvis’ restored 507, we proceeded to get into a fight over the pronunciation of his name: Georg. They were convinced I was full of crap when I told them…

It’s not pointless. You just have to apply science. Take a look at this:

I’ve had two BS traffic stops in my life. One happened 30 years ago when I was in high school and the other just a few months ago. So here they are in chronological order:

I could have used a dashcam\datalogger last year when I was pulled over and falsely accused by a state trooper of reckless driving. His radar reading was 20 mph higher than my true speed and no amount of polite protest was going to convince him otherwise.

I was not a fan of Bangle when his BMW’s first came out. At the time, the E39 M5 was the epitome of cool for me and the want was very strong. His designs were so very different from what I thought a BMW should look like and I was convinced it was a huge misstep for the brand. Now, I regularly look through the listings…

My 48G is still working 25 years later. That thing was $200 back in 1990!
