What’s this Lexus concept car?

It's that time of the year when the world's car manufacturers boldly announce they'll be announcing the reveal of a new car at an upcoming motor show. Usually, this is accompanied by a wantonly ambiguous, shady teaser image to get our senses fizzing.

Well, this is Lexus' entry in the Here's A Notice Of Us About To Give Notice Of A New Car At A Motor Show. It's a ‘new concept vehicle' set for Frankfurt, and all we've been given is the picture above, and the notice that this new concept will be displayed alongside the new GS 300h saloon.

But, doesn't this game feel all-too familiar? Seems TopGear.com's moderately entertaining and often inexplicably frustrating car park-based guessing game - What's In The Top Gear Car Park - has caught on. This is Lexus' version, and you'll only get the answer at the Frankfurt Motor Show reveal, scheduled for 10 September.

So, the rules are simple:

1. Study Lexus' wantonly ambiguous image of a car
2. Guess what it is
3. Type down your answer in our handy new commenting system below

As mentioned, you'll get the answer when the car is revealed. You won't be getting your screen name emblazoned on this page in bold and italic, but you will be filled with a momentary sense of entitlement amongst your fellow TopGear.com commentariat. And surely that's worth its weight in pixels alone, right?
