Photos of the BMW Z4 Concept were leaked hours before the car's official debut at Pebble Beach. With traditional rear-wheel-drive sports car proportions, the Z4 Concept is a pretty thing with a clear preview of the next-generation Z4.

The 2019 Audi e-tron quattro has finally been spotted testing on public roads. Appearing to be sized between the Q5 and Q7 crossover SUVs, the e-tron quattro features a fast roofline, flat grille, and wide stance. Specs are unknown at this time, but expect more than 200 miles of range.

The Porsche Carrera GT supercar is far from new—production ended in 2007—but an example with a mere 25 miles is heading to the auction block. Estimates put the car's value somewhere between $1,100,000 and $1,250,000.
