It's official. The Audi RS 6 Avant is coming to the United States to challenge the Mercedes-AMG E63 S Wagon. Revealed this week, the latest generation of Audi's uber-wagon comes with close to 600 horsepower and styling that can make a supercar look tame in comparison.

The sole surviving 1939 Type 64 (in original condition) and the oldest car to bear the Porsche name was put up for auction during last week's Monterey Car Week. Unfortunately, a major stuff up by auction house RM Sotheby's caused confusion about the bids and the sale was called off before the hammer could be dropped.

This week we took a spin in the 2020 Lincoln Aviator, in range-topping Black Label grade. We'll save the full first drive for you but will say that the mid-size SUVs from the Germans finally have some serious competition from an American brand.

Another vehicle we tested was the 2020 Porsche Cayenne Turbo S E-Hybrid. Porsche's new range-topping Cayenne will hit 60 mph in 3.6 seconds and top out at 183 mph. That's thanks to 670 horsepower generated by a V-8-based hybrid powertrain.

We also drove the 2020 BMW 8-Series Convertible. The car is wider, heavier, and more upscale than the 6-Series it replaces, but sportier. You'd expect that for a car with 523 horsepower and price tag north of $130,000, however.
