Car Aerodynamics Beyond the Norm

When you look at any modern car, the aerodynamic design is always going to be advanced since reducing drag is key to fuel economy. However, you will also see a bunch of stuff that is designed to look like it is aerodynamically important, but it is really just styling. Vanes that look like they do a lot are common but the one that is always there is a diffuser. The shaping of the underside of the rear of the car is designed to look like it is there to increase downforce. The underside of the rest of the car is hardly tailored for downforce, so this is really a styling cue.

There are cars, where the aero is significant, though. The Festival of Speed at Goodwood included an Aston Martin Valkyrie. This is a car where aero really does matter. In these two shots, focus on a couple of areas. The rear of the car has quite a diffuser and this one is definitely functional. A combination of flow route either side of the centre of the vehicle combining and expanding to enhance the downforce under the car. Then look near the front wheels in the wider shot. The wheels are isolated with the flow coming around them and then back out of the sides. So much effort went into this design.

Photomerge Likes Weird Stuff

The panorama merge function in Lightroom is usually pretty good. It can have some odd quirks, and the three different projections can produce very different results at times but, on the whole, I rely on it for my pano creation. Every once in a while, though, it catches me out. At the Festival of Speed, I did find myself using a longer lens to get elements of a shot with the intent of stitching them together later. Partly, this was because the crew was working around the car and I took shots when they were in different places to aim to have an unobscured car in the final shot.

It was the Red Bull RB17 where I was playing with this. When I went to stitch the images together, Lightroom gave an old result. Instead of either having the whole person or no person, it managed to have parts of them only in the shot. I decided to use Photoshop’s photo merge function instead, but it gave the same results. However, it did this by outputting layers with masks which were then editable. I was able to go into the shots and get rid of the bits I didn’t want while bringing out the bits I did. Some of the blending is not perfect in the revised versions but, for a quick solution, it works fine. If I needed to do more with the images, I would fix the flaws with more care.

Goodwood House

The Festival of Speed at Goodwood is spread throughout the grounds of the estate but the main route takes cars right past the front of Goodwood House. They always put up a sculpture involving cars of some sort in front of the house. This year it was three Singer 911s. A pretty dramatic structure. Seeing the house brings back big memories for me. I spent the summer of 1986 living in the stable block just to the left of the main house. That was a cracking summer. Being back there is a treat. Seeing the cars zipping by is an extra!

Goodwood Festival of Speed

More from the archives today.  Only once have I made the trip to the Goodwood Festival of Speed.  For car enthusiasts, this is quite the event.  An enormous variety of motor vehicles are on display and the drive them up the hill across the estate past the main house – a place I am quite familiar with having spent a summer living in the stable block around the corner.  Oh how I wish they had done this when I was there!

My one trip would have probably been in 2003 shortly before leaving the UK.  I only got a few photos but there are some rather unusual cars in the shots I did take.  I thought that a few of you are in to cars and might be interested in what was there.  Maybe some of you were there too?  One day I will try and be back when it is on again and make another trip.
