The Alpina Roadster S is a sports car manufactured and marketed by Alpina, a German car manufacturer, from 2003 to 2007. In 2003, Alpina released the Alpina Roadster S at the 2003 Frankfurt Motor Show and based the car on the BMW Z4 (E85).

History of Alpina Roadster S

The Roadster S made its debut at the IAA 2003 in Frankfurt, Germany, in September of that year. It was not a replacement for any Alpina models because there was no Alpina variant of the BMW Z3-series. Body-in-white was manufactured at BMW's Spartanburg plant and shipped to Alpina's Buchloe facility for final assembly. Z4 3.0i Z4 Roadster S, on the other hand, was built using the Z4 3.0i Z4 Roadster S as a base for upgrading the Z4 3.0i and incorporating Alpina's unique components. The Roadster S was only produced in Europe for two years (2004 and 2005), totaling 370 vehicles, of which 167 were right-hand-drive models for the United Kingdom market. In January 2006, BMW discontinued supplying engines to Alpina because the M54 engine did not comply with the new Euro 4 emission laws, which were in existence at the time. Through dealership stocks, the automobile was still available for purchase until 2006.


Alpina sold the 2005 Alpina Roadster S with an MSRP of £37,850 (£60,219 or $78,688 in 2022). Online car auction websites offer different styles and upgrades. Prices range from $25,000 to $50,000.


Interior Features of Alpina Roadster S

Alpina manufactured the interior of Roadster S in three color combinations for its dashboard and steering wheel: black leather with blue and green stitching, red leather with red stitching, and beige with maroon piping and maroon stitching. More interior features include an Alpina blue instrument cluster, logos and badges, heated sports seats, door sills, and an overhead plaque with the car's production number. Roadster S' interior also sports Alpina leather sports seats and floor mats. Overall, the car manufacturer made over 2,000 modifications to its interior.

Exterior Features of Alpina Roadster S

Alpina made minor modifications for its exterior, including the installation of the front and rear spoiler lips with Alpina lettering. The manufacturer also installed 18-inch Alpina Dynamic alloy wheels with Michelin Pilot Sport tires, "Roadster S" badging at the rear, and front quarter-panel badges of "3.4 S". Available exterior colors were Alpina Blue, Japan Red, Sterling Red, Black Sapphire, Royal Red, Black Sapphire, and Maldives Blue. Alpina also offered the Alpina Roadster S as a hardtop option.
