The Alpina RLE Roadster (Z1), produced between 1990 and 1991, features a compact and sporty design typical for a roadster of its era. The length measures approximately 4,140 mm (163 inches), the width is about 1,665 mm (66 inches), and the height stands at roughly 1,260 mm (50 inches). These dimensions contribute to its agile handling and distinctive roadster styling, offering a low and wide stance on the road.
The wheelbase of the Alpina RLE Roadster (Z1) is approximately 2,470 mm (97.2 inches). A relatively short wheelbase like this enhances the car’s agility and responsiveness, making it nimble in corners and more engaging to drive. This is a typical characteristic for roadsters, which prioritize sporty handling and driver feedback over long-distance comfort.
The curb weight of the Alpina RLE Roadster is estimated to be around 1,200 kg (2,646 lbs). This relatively light weight helps in achieving better acceleration, braking, and cornering performance, all key attributes for a sports-oriented roadster. The lower weight contributes to an enhanced power-to-weight ratio, allowing the engine’s output to be effectively translated into spirited driving dynamics.
The Alpina RLE Roadster has a ground clearance of approximately 140 mm (5.5 inches). This low clearance emphasizes handling precision and a lower center of gravity but may require drivers to be cautious over speed bumps or uneven urban surfaces. While it is practical for regular city driving, care should be taken to avoid obstacles that could scrape the undercarriage.
Yes, the Alpina RLE Roadster fits comfortably into a typical residential garage. With its length of 4,140 mm (163 inches) and width of 1,665 mm (66 inches), it is smaller than many modern cars and sports cars. Most standard garage spaces, which are roughly around 6,000 mm (236 inches) long and 3,000 mm (118 inches) wide, can accommodate this roadster with room to spare for easy ingress and egress.
The Alpina RLE Roadster offers a snug but driver-focused interior typical of classic roadsters, emphasizing sporty seating and minimalistic design rather than expansive cabin space. Compared to contemporaries like the Mazda MX-5 Miata or BMW Z3 from that time, the RLE's interior prioritizes driving engagement but might offer slightly less passenger space due to its compact overall dimensions. The cabin is designed more for short, spirited drives than for long-haul comfort.
The Alpina RLE Roadster (Z1) itself was a specialized limited edition based on the BMW Z1 platform, which was its predecessor in terms of chassis and design. Compared to the BMW Z1, the Alpina RLE maintains very similar dimensions, with only slight modifications primarily for styling and performance tuning. The length, width, and height remain close, preserving the compact and sporty proportions of the Z1, while Alpina enhancements focused on performance and exclusivity rather than size changes.
In comparison with other early 1990s roadsters like the Mazda MX-5 Miata, Porsche 968 Cabriolet, and BMW Z3, the Alpina RLE Roadster is similar in compactness and low profile. Its length of 4,140 mm is slightly longer than the MX-5's approximately 3,970 mm but shorter than the Porsche 968 Cabriolet which is about 4,390 mm. Width-wise, it sits in the middle, offering a balance between stability and nimbleness. Overall, it holds its own in terms of size, emphasizing a pure sports-car, driver-focused approach similar to its rivals.
The Alpina RLE Roadster has a fuel tank capacity of around 52 liters (approximately 13.7 US gallons). This size is fairly typical for sports cars of its era, allowing for a good balance between weight and driving range. With combined fuel consumption figures that are moderate for a sporty roadster, drivers can expect a practical range between refueling stops, making it suitable for both spirited weekend drives and occasional longer touring.
The Alpina RLE Roadster is a highly exclusive and rare variant derived from the BMW Z1, bearing distinctive Alpina tuning. It features performance enhancements such as tuned suspension for sharper handling, exclusive Alpina wheels, and upgraded interior trim and badging reflecting Alpina’s craftsmanship. The engine, typically the BMW 2.5-liter inline-six, receives Alpina-specific tuning for slightly increased power output and more refined throttle response. These features combine to make the RLE a more focused, collector-oriented roadster with a blend of BMW’s engineering precision and Alpina’s bespoke attention to detail.
