Breaking: 2015 Corvette Z06 drops its top for New York auto show

This is the new 2015 Corvette Z06 convertible, the Stingray for owners who want it all, shown a little earlier than we expected. Buyers get the Z06 engine, racing suspension and brakes, and now, for the first time since 1963, they can get that package with a convertible top, as we'll see at the New York auto show. “Until recently it was not possible to create a lightweight, open-roof structure strong enough to cope with the braking, cornering and acceleration of Corvette's top performance models,” said Corvette chief engineer Tadge Juechter.

2013 Buick Verano Turbo turns up the power

Buick is adding a turbo variant this fall as the premium model for the Verano lineup. While it's meant to be sporty, the idea behind the sedan is to offer buyers a reasonably powerful option that allows for more amusing commutes, but admittedly, it isn't a dedicated performance model. This is a measured approach, which means extra output for expressway merges and launches from lights, but no hard-core suspension or brake packages.
