The BMW 6 Series Gran Turismo (G32) 630i M Sport is a premium 5-door fastback/liftback executive car launched in 2017 (produced until around 2023, with a facelift in 2020). It blends the sleek, coupé-like styling of a grand tourer with exceptional practicality, making it ideal for long-distance comfort while offering sporty dynamics.

Key Specifications

• Engine: 2.0-litre inline-4 turbocharged petrol (BMW B48) with TwinPower Turbo technology, including High Precision Injection, VALVETRONIC, and Double-VANOS. It delivers 258 hp (190 kW) at 5,000–6,500 rpm and 400 Nm of torque from 1,550–4,400 rpm.
• Transmission: Smooth 8-speed Steptronic automatic (ZF 8HP) with rear-wheel drive (RWD). Optional xDrive all-wheel drive was available in some markets.
• Performance: 0–100 km/h (0–62 mph) in approximately 6.3–6.5 seconds, with a limited top speed of 250 km/h (155 mph).
• Dimensions: Length 5,091 mm, width 1,902 mm, height 1,538 mm, wheelbase 3,070 mm. It is notably longer and taller than a standard 5 Series, providing a more imposing presence.
• Fuel Economy: Combined consumption around 6.5–7.0 L/100 km (depending on wheels, options, and test cycle), with a 68-litre fuel tank for strong real-world range (up to 1,000+ km reported in efficient driving).
• Weight: Unladen around 1,720–1,860 kg (EU).

Design and M Sport Package

The Gran Turismo body style features a long, flowing roofline that merges coupé elegance with a practical hatchback tailgate. The M Sport variant adds:

• Sportier aerodynamic body kit
• M-specific suspension (firmer tuning for better handling)
• M Sport brakes
• 19-inch (or optional 20-inch) M alloy wheels
• High-gloss Shadowline exterior trim
• Quad exhaust tips
• Anthracite headlining
• M Sport steering wheel, pedals, and illuminated door sills

It sits on air suspension at the rear (with self-levelling) for a composed ride, especially when loaded.

Interior and Practicality

This model excels as a “grand tourer”:

• Spacious 5-seater cabin with generous rear legroom and headroom (three adults fit comfortably).
• Massive luggage capacity: 610 litres (seats up) expanding to 1,800 litres (seats folded) — significantly more than a 5 Series saloon.
• High-quality materials, with M Sport adding sport seats, Sensatec dashboard, and options like panoramic glass roof, 4-zone climate control, and premium leather.
• Modern tech includes iDrive with large displays, optional Head-Up Display, and advanced driver assistance features.

The rear seats can slide and recline for extra versatility, and the self-levelling air suspension helps maintain a level ride when carrying heavy loads or towing (up to 2,100 kg braked).

Driving Experience

Reviewers praise its balance of comfort and engagement. The turbo four-cylinder offers strong mid-range pull for effortless overtaking, while the 8-speed gearbox shifts seamlessly. It feels refined and quiet on highways yet responsive in corners thanks to the M Sport setup. Fuel efficiency is impressive for its size and performance, often achieving 20+ km/l in relaxed long-distance driving.

Overall, the BMW 6 Series G32 630i M Sport Gran Turismo is a stylish, versatile alternative to a traditional saloon or estate. It targets buyers wanting luxury, space, and effortless performance without sacrificing driving enjoyment. Later models included mild-hybrid assistance for slightly better efficiency and emissions.
