BMW 507 Model

The BMW display at the 2006 and 2007 Portland International Auto Shows featured some display cases with BMW accessories and memorabilia, and models of past and present BMW cars, including this model of the BMW 507.

The BMW 507 roadster was produced from 1956 to 1959, with a body made entirely of aluminum. Only 252 of the V8-powered sports cars were built, as BMW lost money on every one sold. One of them was owned by Elvis Presley.

2006 BMW 550i

The 5-series is the mid-range entry of the BMW line. The 2006 525i and 530i offered the same 215-horsepower and 255-horsepower 3.0-liter double overhead cam in-line six-cylinder engine choices as the smaller 3-series, but the 550i features a 360-horsepower 4.8-liter double overhead cam 32-valve V8. In addition to the standard 6-speed manual and optional 6-speed StepTronic automatic transmissions of the 3-series, the 530i and 550i also offered a 6-speed manual sequential gearbox.

2006 BMW 325i

The "base" model of BMW is the 3-series. Shown here is the then-new 3-series sedan, Automobile Magazine's 2006 Automobile of the Year. The 3-series was powered by a 3.0-liter double overhead cam in-line six-cylinder engine rated at either 215 horsepower in the 325i or 255 horsepower in the 330i; both were capable of accelerating from 0 to 60 miles per hour in less than 7 seconds. The 3-series featured a standard 6-speed manual transmission or an optional 6-speed StepTronic automatic transmission, standard run-flat tires, and available all-wheel drive.

2006 BMW Z4

The 2006 BMW Z4 roadster offered the 215-horsepower and 255-horsepower 3.0-liter double overhead cam in-line six-cylinder engines and 6-speed manual and StepTronic automatic transmissions of the 3-series in a 2-seat convertible with a DVD navigation system and a top that lowered in 10 seconds, starting at under $35,000.

2006 BMW M5

The 2006 M5 was a high-performance version of the 5-series, and was BMW's fastest and most powerful offering. Powered by a 500-horsepower 5.0 liter double overhead cam 40-valve V10 engine with a 7-speed sequential manual gearbox, the M5 could accelerate from 0 to 60 miles per hour in 4.5 seconds and reach a top speed of 155 miles per hour.

2006 BMW 750i

At the top of the BMW ladder is the 7-series, available in 2006 as either the 750i, with the same 360-horsepower 4.8-liter double overhead cam 32-valve V8 engine used in the 550i and 650i, or the flagship 760i, with a 438-horsepower 6.0-liter double overhead cam 48-valve V12, both with a 6-speed StepTronic automatic transmission.

2006 BMW 650i Coupe

The 2006 BMW 650i was available as a coupe or convertible, with the same 360-horsepower 4.8-liter double overhead cam 32-valve V8 engine and 6-speed manual, StepTronic automatic, and manual sequential transmissions available in the 550i sedan, only in a sleek sports-car body.
