Alright, let's take a dive into the world of livery making, since there seems to be some confusion on how things work in the world of a race car's paint job. Liveries, for those that don't know, are massive political landscapes. The 1999 BAR F1 cars are examples of such politics and what comes out as a result. The year before, BAR wanted to run one car in the Lucky Strike paint scheme, and the other in the 555. F1/FIA said no, so the following season we got the split livery, an unapologetic middle finger to the rule mongers of F1.
@D-Max I don't recall reading that there's a requirement for only one title sponsor permitted. Plenty of race cars have multiple sponsors plastered all over their racecars. Here's an example:
Hey look at that! It's a race car that has BP
and Castrol branding, at one of the top echelons of motorsport no less. Not only that, but it also features sponsorship from Ford, Abu Dhabi and Karcher. Is this an attractive livery? Not necessarily. Is it a split livery? No. It
is symmetrical however, and it's the result of five different sponsors all requiring their logos and branding be featured on the car a certain way. bp ultimate clearly mandated it be featured on a light green background. Castrol required a dark green. Abu Dhabi wanted a red, Ford a Blue and Karcher a white. All wanted equal space on each side of the car they were featured on.
My livery, being asymmetrical and not based on any pre-existing liveries (it was inspired by the '93 BP GT-R and the '99 Mugen Castrol NSX though), was able to feature bp prominently on one side, and Castrol on the other as well as the front. I chose a yellow field to put the bp logo on as I felt that would be more akin to their branding and would contrast with the Castrol side.
Let's look at another livery that's the result of series politicking and sets additional precedent for Fuel and Lubricant co-sponsorship:
Joey Logano's Penske Ford just won the NASCAR championship this season. It's symmetrical and very much Shell-oriented. It's the result of NASCAR's fuel supplier Sunoco requiring any rival company to feature it's lubricant brand in addition to their fuel brand in order to sponsor a car in the series.
Last but not least, one more example. Symmetrical as well and featuring Castrol no less:
I had never heard of ARAL ultimate before, but even as I googled it, I guessed to myself, "It's probably bp's German subsidiary." Boy wouldn't you know how much I hate being right? Naturally, ARAL's corporate colors are blue, so it's brand would, of course, be featured on a blue field. Castrol is again featured on a green field. Is it symmetrical? Yes. Is it a split livery? As I'm sure you've likely seen this livery before and not even considered it as such, I'd say the answer to the Audi (and now BMW that features it) as well as both Ford's above is "no". But they are very symmetrical!
So to end off, just because I followed the competition brief in making an asymmetrical livery does not automatically mean it's a split livery just because I did what every livery ever has had to do. That being distinctly feature the primary sponsors in their own fields of color. Even if those fields were determined by my own choosing.
Regardless, I updated my entry anyways and cleaned up a few things while I was at it.
