March 15 was the last day of the 85th Geneva International Car Show.

You might call the last day of the show the “butt end” − I would never use such a term myself, but you might − so what butter, uh, better way to celebrate than a lineup of superbutts: ten perfectly polished posteriors for your personal perusal.

Bugatti Veyron: I’m not sure about that exhaust

McLaren 650 S Spider

Koenigsegg Agera RS: for when the Agera R just doesn’t cut the mustard

Lamborghini Adventador: no flab, it’s all muscle

Porsche 911 Turbo S Cabriolet: that’s a view never to get bored of . . . because it’s been virtually the same for 50 years, but unlike me it just keeps getting faster

The fuel-cell powered Quant F seems to have gone a bit wild with the lipstick

Koenigsegg Regera

Alpha Romeo 4C: yellow is flattering but avoid mud and rain, drizzle, dust, fog, and sprinklers

No, you didn’t wander into the vintage section by mistake; this is indeed a current-production Morgan Plus 4 hot off the production line

Pagani Huayra. . . and is that Bruce Wayne?

So do these supercar superbutts look bigger in carbon fiber or is it slimming? I don’t know what you think, but did you see the hips on that Koenigsegg Regera? I would have thought a few more laps on the Nürburgring might have been in order before trying to squeeze onto that little carbon fiber chassis (black would have been more slimming).

If you would like to see more of these cars, and by that I mean more of the cars shown above, and from different angles, please see Geneva International Motor Show 2015 Photo Essay: Warning, Supercar Heavy!
