2018 Proton X70 Dimensions, Size & Specs

With a width of 1831 mm (72.0 inches), the Proton X70 is moderately wide for a compact SUV. This width provides a stable and comfortable driving experience, yet it remains relatively easy to maneuver in urban environments and parking lots. However, drivers should still be cautious in narrow lanes or tight spaces as the width requires some attention to curb clearance and adjacent vehicles.

The Proton X70's curb weight ranges from 1660 kg to 1725 kg (3,660 to 3,802 lbs). This weight range is typical for a vehicle in the compact SUV segment, offering a balance between solidity and efficiency. The relatively modest weight contributes to decent fuel economy and responsive handling dynamics, although it may not be as nimble as lighter crossover counterparts.

The Proton X70's length of 4519 mm (177.8 inches) and height of 1694 mm (66.7 inches) mean it fits comfortably into most standard residential garages, which typically have an internal length of around 5400-6000 mm (213-236 inches) and a height clearance above 2000 mm (78 inches). Its dimensions allow for easy garage storage without concern for tight clearance, though wider aftermarket accessories might require caution.

The Proton X70 offers tire sizes of 225/65 R17, 225/60 R18, and 225/55 R19, with corresponding rim sizes of 17, 18, and 19 inches. Larger rims with lower-profile tires typically enhance handling and road grip but can reduce ride comfort due to stiffer sidewalls. Conversely, smaller rims with higher-profile tires tend to absorb bumps better, improving ride comfort, especially on rough roads.

While exact interior dimensions may vary, the Proton X70 provides generous passenger space typical of a compact SUV, with ample headroom and legroom for five occupants. Cargo capacity is competitive within its class, offering around 400-500 liters of luggage space with rear seats up, which expands significantly when the rear seats are folded down, suitable for family trips and everyday hauling needs.

The Proton X70's height of 1694 mm (66.7 inches) places drivers higher above the road compared to sedans, offering a commanding view of traffic and surroundings, enhancing overall driving confidence and safety. This higher stance aids in better road visibility and ease of entry and exit but may slightly impact aerodynamics, which is common across SUVs.

The Proton X70 is the brand's first SUV developed with significant input from Geely and represents a major step up from Proton's previous SUV-like offerings, which were limited or rebadged. It is larger, more modern, and more feature-rich than previous models such as the Proton X50’s predecessors. It provides more space, advanced safety features, and modern tech, establishing Proton in the competitive compact SUV market.

The Proton X70 competes well against compact SUVs like the Honda CR-V, Mazda CX-5, and Hyundai Tucson in terms of exterior dimensions and features. Its length of 4519 mm (177.8 inches) and width of 1831 mm (72.0 inches) are comparable, offering competitive interior space. While some rivals may offer slightly lighter curb weights or different engine options, the X70 stands out with its combination of size, comfort, equipment, and pricing.

The Proton X70 has rim options of 17, 18, and 19 inches paired with tires sized 225/65 R17, 225/60 R18, and 225/55 R19 respectively. Larger 19-inch rims enhance sporty handling and sharpness on smooth roads, while the 17-inch variants deliver a more comfortable ride, especially on uneven or rough surfaces. The tire profile plays a key role in balancing grip and ride comfort across urban and highway driving.
