The boxes are just more data points (engines) that they have data for. The square ones are diesel engines, the diamond ones are petrol engines. They've highlighted a few data points as stars, but the others are just other engines that are perhaps less relevant, so not highlighted. The diesel race engine they've highlighted comes in before the year 2000, so if the scales are accurate then that's not the Audi racing unit. There were a few diesel touring cars in the 90s, but they weren't really at the level of technology that diesel LMPs and touring cars ran in the 00s.
The line graph/arrow they've drawn through the points isn't accurate though. Both the lines should be significantly lower if they're to be accurate.
