This week, Ate Up With Motor wishes you all happy holidays -- or is it Holidays?

Read on for a special holiday message...

Between 1971 and 1978, Mazda launched nine new rotary-engined vehicles; by 1979, only three survived, and the company had come perilously close to collapse. In the second part of our history of Mazda's early rotaries, we take a look at those vehicles -- including the RX-2, RX-3, RX-4, and RX-5 -- and trace Toyo Kogyo's dramatic reversals of fortune in the 1970s.

Mazda has a long history with rotary engines, going back to the Cosmo Sport and R100 of the late 1960s. With the recently announced demise of the RX-8 -- the last rotary-engined model still in production -- we look back at the origins of the Wankel engine and the history of Mazda's early rotary-engined cars.

Recently, we were invited to an event at the Petersen Automotive Museum in Los Angeles, introducing the newly restored 1934 Ford Model 40 Special Speedster, an aluminum-bodied one-off originally designed by stylist E.T. (Bob) Gregorie for Edsel Ford's personal use. This week, we explore the history of that car and its lesser-known predecessor, and take a look at the evolution of Edsel Ford and Bob Gregorie's role in Ford Motor Company styling.

The Swedish automaker Volvo is best known for its solid (and often square) sedans and wagons, but starting in 1961, it also offered a sleek two-door sports coupe called the P1800 -- best known for its role in the 1960s TV version of The Saint. This week, we look at the origins and evolution of the P1800, its 1800S and 1800E successors, and its ultimate metamorphosis into a sporty two-door shooting brake, the 1972-1973 1800ES.

In mid-1949, GM's senior divisions introduced a trio of glamorous new models -- the Cadillac Coupe de Ville, the Oldsmobile Futuramic 98 Deluxe Holiday coupe, and the Buick Roadmaster Riviera -- that are popularly, if incorrectly, considered the first pillarless hardtops. This week, we consider the origins of this quintessentially  (though not uniquely) American body style, and examine the development of the '49 Roadmaster Riviera.
