The curb weight of the 1998 Mazda Roadster (NB) is approximately 1010 kg (2227 lbs). This lightweight design is pivotal to its dynamic performance, allowing for quick acceleration, precise handling, and enhanced fuel efficiency. The relatively low weight helps the car achieve nimble cornering and responsiveness, key attributes for a sports roadster. Additionally, the lighter mass reduces the load on the suspension and brakes, improving overall driving enjoyment and vehicle agility.

The standard rim size for the Mazda Roadster (NB) is 14 inches in diameter. The tire size fitted is typically 185/60 R14. This combination offers a balanced ride quality with good grip, especially suited to the car's lightweight and sporty profile. The 185 mm tire width ensures adequate contact with the road for confident handling, while the 60 aspect ratio balances comfort with responsive cornering. Overall, this setup is optimized for the car's intended use as a fun and agile two-seater roadster.

Yes, the 1998 Mazda Roadster (NB) fits comfortably into a standard single-car garage. Given its compact dimensions — 3955 mm (155.7 inches) length, 1680 mm (66.1 inches) width, and 1235 mm (48.6 inches) height — it is well under typical garage size limits. Most standard garages are at least 6 meters (about 20 feet) in length and around 3 meters (about 10 feet) in width, which provides ample space for the Roadster with additional room for opening doors and maneuvering. Its slim width and low height also make parking particularly convenient.

Compared to its predecessor, the 1998 Mazda Roadster (NB) is slightly larger in overall dimensions while maintaining a similar compact footprint. The NB generation measures 3955 mm in length versus approximately 3980 mm for the NA, so it is marginally shorter by about 2.5 cm. The width increased slightly from around 1675 mm to 1680 mm, and the height dropped slightly from approximately 1240 mm to 1235 mm. These subtle changes result in a car that feels a bit more refined and stable without losing the nimble driving characteristic. Additionally, the NB improved in weight distribution and structural rigidity, enhancing handling compared to the NA.

The 1998 Mazda Roadster (NB) stands out in its segment due to its compact and lightweight design when compared with similar roadsters like the Honda S2000 or Toyota MR2 Spyder. For example, the Honda S2000 is longer at about 4154 mm (163.5 inches) and wider at 1770 mm (69.7 inches), making the NB smaller and potentially more agile in tight corners and urban environments. The Roadster's lighter curb weight of 1010 kg (2227 lbs) also tends to be lower than many rivals, contributing to its reputation for nimble handling. This compact size and low weight balance make it an excellent choice for enthusiasts valuing pure driving dynamics in a small package.

While the Mazda Roadster (NB) is a two-seater sports car prioritizing driving experience over spaciousness, its interior is thoughtfully designed for comfort within its compact frame. The width of 1680 mm (66.1 inches) translates to snug but sufficient shoulder room for two occupants. The low height of 1235 mm (48.6 inches) gives the car a sleek profile, but headroom is optimized by the roadster’s convertible design, offering ample vertical space when the top is down. Legroom is focused on accommodating a sporty seating position rather than expansive space. Overall, the cabin balances intimacy with comfort for spirited driving.

The 14-inch rims paired with 185/60 R14 tires are a balanced choice that support the Mazda Roadster (NB)’s lightweight, agile character. Smaller diameter rims help keep the unsprung mass low, which benefits suspension responsiveness and ride comfort. The 185 mm tire width ensures a good footprint for grip without compromising the car’s maneuverability. The 60 aspect ratio provides enough sidewall height to absorb road imperfections yet maintains enough stiffness to preserve sharp handling. This tire and rim configuration underscores the car’s emphasis on nimble, precise road feel rather than outright aggressive cornering grip.

The 1998 Mazda Roadster (NB), due to its compact size (3955 mm length, 1680 mm width, 1235 mm height) and lightweight design, is quite suitable for everyday use, especially in urban and suburban settings. Its small footprint makes parking and city driving easy and less stressful. Its convertible roadster style offers an enjoyable open-air driving experience, which can be appreciated daily in good weather. However, its limited cargo space and two-seat configuration may be a constraint for families or heavy cargo needs. The car also benefits from simple handling and relatively low running costs, making it pragmatic as a daily driver for those prioritizing fun.

The 1998 Mazda Roadster (NB) offers several improvements over the first-generation Roadster (NA), starting with refined styling that is slightly more aerodynamic and modernized. Dimensionally, the NB is marginally more compact in length but slightly wider, lending improved stability without compromising nimbleness. Mechanically, the NB features updated suspension geometry and lighter weight construction at around 1010 kg (2227 lbs), improving handling, ride comfort, and fuel efficiency. The interior was redesigned for improved ergonomics and comfort, including better safety equipment. This generation also brought subtle powertrain enhancements, making the NB a more capable and enjoyable roadster while maintaining the core characteristics that made the NA beloved by enthusiasts.
