Chevrolet Corvette ZR1 will be Indy 500 pace car

The 2013 Chevrolet Corvette ZR1 will be the pace car for this year's Indianapolis 500--a fitting victory lap as the current sixth-generation Corvette heads for the end of its production run and the end of this version of the ZR1. The Indy pace-car Corvette will wear the 60th-anniversary trim package--an arctic white exterior with silver stripes down the center of the car and a blue interior with suede leather coverings on the steering wheel, center console and in the seats. Changes for the pace car include only the addition of a light bar on the roof, some racing-safety equipment and race logos.

Porsche plans four-door Panamera convertible

A series of European and U.S. patent applications obtained by AutoWeek show that Porsche remains committed to building a four-door convertible version of its flagship Panamera, despite recent comments from Zuffenhausen insiders indicating the car had been canceled. The new car, depicted in official drawings that accompany the latest Porsche patent applications filed in February, eschews the two-door route taken by all of its upmarket rivals for a four-door body.
