Rolls-Royce has redesigned the Ghost, and we've just tested the latest generation. The car definitely has big shoes to fill. Its predecessor, launched in 2009, is the most popular Rolls-Royce in the marque's 116-year history. It also helped to reduce the average age of a Rolls-Royce buyer to a relatively young 43.

BMW has a redesigned M4 coupe racing into showrooms next March, and not far behind it will be an M4 Convertible. The drop-top is still out testing and should offer the same 473- (base) and 503-horsepower (Competition) power ratings as the coupe when finally revealed.

Acura has previewed its redesigned MDX, which is headed to showrooms next year. The new crossover SUV will be longer, wider and lower than the outgoing generation, and it will also feature a sporty Type S variant packing 355 hp.
