2018 Genesis G70 Dimensions, Size & Specs

The curb weight of the Genesis G70 ranges between 1595 kg (3516 lbs) and 1775 kg (3913 lbs), depending on the trim and options selected. This relatively moderate weight for a luxury sports sedan contributes to a dynamic yet composed driving experience. A lower curb weight typically enhances agility, acceleration, and fuel efficiency, while the upper range accommodates additional features and performance enhancements, slightly impacting fuel consumption but offering more stability. The G70's well-balanced weight distribution is optimized for confident handling and sporty driving dynamics.

With a width of 1850 mm (72.8 inches), the Genesis G70 offers a spacious cabin that comfortably accommodates four to five passengers. This width ensures adequate shoulder room while maintaining a sleek exterior profile. The wide stance enhances road presence, stability during cornering, and overall driving confidence. The width also contributes positively to the vehicle’s handling characteristics on various road surfaces, balancing comfort and performance without sacrificing maneuverability in urban environments.

The Genesis G70 comes equipped with rims sized at 17, 18, or 19 inches, paired with tire sizes of 225/50 R17, 225/45 R18, 225/40 R19, and 255/35 R19. Larger wheels and lower-profile tires, like the 19-inch rims, enhance steering precision, cornering grip, and aesthetic appeal but may slightly reduce ride comfort. Conversely, smaller 17-inch wheels with higher-profile tires generally offer a smoother ride and better absorption of road imperfections, ideal for urban and long-distance cruising. This range allows buyers to prioritize comfort or sporty handling as desired.

Yes, the 2018 Genesis G70 typically fits comfortably into a standard residential garage. Most single-car garages in residential settings are roughly 2440 mm to 3050 mm (96 to 120 inches) wide and 4877 mm to 6096 mm (192 to 240 inches) deep, which is ample space for the G70’s dimensions of 4685 mm (184.4 inches) in length and 1850 mm (72.8 inches) in width. Its 1400 mm (55.1 inches) height is well below standard garage door heights, ensuring easy entry and exit without clearance issues.

The Genesis G70, introduced in 2017 as Genesis' entry into the compact luxury sedan segment, does not have a direct predecessor under the Genesis brand, as it marked Genesis’ debut in this market category. However, compared to earlier Hyundai models from which Genesis originally derived, the G70 is more refined and slightly larger in overall dimension and interior space, focusing on premium luxury and performance. It is notably sportier and more upscale than Hyundai Elantra or Sonata sedans, reflecting its positioning as a standalone luxury model.

The Genesis G70 measures 4685 mm (184.4 inches) in length and 1850 mm (72.8 inches) in width, which places it very close in size to competitors like the BMW 3 Series and Audi A4. For example, the BMW 3 Series (G20 generation) is about 4709 mm (185.4 inches) long and 1827 mm (71.9 inches) wide, while the Audi A4 is around 4730 mm (186.2 inches) long and 1847 mm (72.7 inches) wide. The G70 stands out with a slightly wider track, offering a stable feel, and comparable length that balances maneuverability with interior space. This dimensional competitiveness helps it assert itself firmly in the compact luxury sedan market.

While the overall exterior height of the Genesis G70 is 1400 mm (55.1 inches), the interior height provides enough headroom to accommodate passengers comfortably, typically around 980-1000 mm (38.6-39.4 inches) in the front seats and slightly less in the rear. This ensures that average-sized adults can sit upright without feeling cramped, contributing to a comfortable and roomy cabin experience. The G70's low roofline is designed to balance sleek aesthetics with functional passenger space, providing a sporty yet practical interior.

The 2018 Genesis G70 offers a trunk capacity of approximately 340 liters (12 cubic feet), which is typical for the compact luxury sedan segment. This space is adequate for daily errands, small luggage, and grocery shopping, accommodating several suitcases or shopping bags comfortably. While not as large as midsize sedans or SUVs, the G70’s trunk space balances practicality with its sporty design and more compact size. For those needing extra cargo room, the rear seats can fold down to extend storage capacity, adding versatility for longer trips or bulkier items.

The Genesis G70’s dimensions, including its 1400 mm (55.1 inches) height and 1850 mm (72.8 inches) width, are engineered to optimize aerodynamic efficiency. The relatively low height reduces drag by lowering the frontal area that encounters air resistance. The wide stance improves stability and allows for a more sculpted body profile with smooth airflow around the sides. These factors collectively help the G70 achieve better fuel efficiency, reduce wind noise, and enhance high-speed stability, contributing to a comfortable and efficient driving experience.
