The 2012 Porsche Cayman R

The 2012 Porsche Cayman R does 0 to 60 in 4 seconds and it's street legal.

DAMASCUS, MD. (MarketWatch) — The barebones Porsche Cayman was already a pretty fast car, but German engineers like to tinker with things. 

Hence the Cayman R for 2012 — a street-legal version of Porsche’s Cayman racing entry — and more changes coming in 2013, when, according to Road & Track, the headlights and taillights will be repositioned and there may be increased power in the form of a new engine. 

One easy way to get more out of the current design is weight reduction, and Porsche’s engineers have increased performance by removing the air conditioning, sound system and just abut anything else that could be taken out without hurting performance. That makes the R model about 121 pounds lighter than the standard Cayman.

And that means the 3.4 liter, 330-horse inline six that powers the Cayman R is good for zero to 60 in a 4-second range.
