Who knew the Toyota Avalon could be so... sporty? SEMA isn't just about tuning no-brainers like the Ford Mustang and Scion FR-S, it's about showing what's possible for a wide variety of cars, even seemingly geriatric machines like the big Avalon.

But remember, Toyota is seriously considering a sportier version of its Avalon flagship – we first brought you this news earlier in the year. And while these SEMA concepts aren't intended for production, nobody is ruling out that something very similar might make it to showrooms in the near future.

The stealth Avalon you see above is the DUB Edition, rolling on 22-inch matte black wheels and featuring a completely de-chromed exterior with blacked-out elements. The DUB Avalon doesn't offer any tweaks to the 3.5-liter V6, but behind that tinted glass is a totally black interior with suede accents on the seats and many of the touchable surfaces.

Moving on, Toyota has brought a TRD Edition Avalon that uses plenty of parts from the company's in-house tuning catalog, and showing that even hybrids can be sporty, the Avalon HV gets a meaner, sleeker look. Have a look at all three in the attached galleries.
