BMW 730i
The BMW 730i is the entry point to the 7 Series flagship range — powered by a turbocharged 2.0-litre four-cylinder engine, it delivers genuine luxury sedan presence with competitive running costs, available in both standard-wheelbase (G11) and long-wheelbase (G12) configurations across two generations.
Overview
The BMW 730i entered the G11 7 Series lineup in 2016 as the range-entry model, positioning a turbocharged 2.0-litre B48 four-cylinder beneath the long bonnet of BMW's flagship saloon. Producing 258 hp and 400 Nm of torque, the 730i delivers 0–100 km/h in a respectable 6.0 seconds — performance that belies its four-cylinder configuration, thanks in part to the 8-speed ZF automatic transmission and the inherently lightweight construction BMW used for the G11 generation, including carbon-fibre reinforced plastic (CFRP) in the core structure.
The G70 generation 730i (2023 onwards) received a revised B48 unit producing 286 hp, paired with an updated iDrive 8 infotainment platform, revised exterior styling with vertically stacked headlights and a bolder kidney grille, and expanded standard equipment. xDrive all-wheel drive became available in selected markets. The 730i distinguishes itself from lesser saloons through its full 7 Series chassis package: air suspension with road preview, executive rear seating, and an interior specification that rivals dedicated luxury marques.
In Azerbaijan, the 730i is relatively uncommon — most buyers stretching to the 7 Series tend to select the 740i six-cylinder or higher. This creates a genuine value opportunity: the 730i offers essentially identical exterior presence and cabin quality to the 740i at a meaningfully lower price. BMW Baku can service the B48 engine as a routine item. For buyers who cover primarily urban and intercity distances where the B48's efficiency is most relevant, the 730i represents the most cost-efficient way into a current-generation flagship BMW.

Competitor Snapshot
Competitor choice in Azerbaijan should account not only for headline specs, but for service ecosystem, parts availability, and ownership confidence over your actual routes.
| Model | Core Strength | Main Compromise (Local Context) |
|---|---|---|
| Mercedes E 350 (W213) | Refined V6 engine, strong brand recognition in Azerbaijan, wide dealer support | Less prestigious than S-Class positioning; 730i offers full flagship cabin at similar price |
| Audi A6 2.0T (C8) | Quattro AWD standard, advanced MMI tech, strong residual values in Europe | Smaller interior than 7 Series; less executive cabin drama |
| Lexus ES 350 (XV70) | Outstanding reliability record, low maintenance costs, smooth V6 | Rear-wheel drive architecture less refined for luxury; no air suspension option |
| Mercedes S 350d (W222) | Comparable prestige and interior quality to 7 Series | Diesel engine less desirable in Azerbaijan; older generation now showing age |
Repair & Service in Azerbaijan
BMW has an established service presence in Baku through authorised dealerships and independent specialists familiar with the brand. Parts supply for common maintenance items is generally reliable, though specialist components for performance models and older generations may require additional lead time.
- B48 timing chain: robust design, but oil service compliance is critical — irregular oil changes are the primary cause of chain stretch
- Air suspension bags: inspect for cracking or slow leaks on G11 cars above 80,000 km; replacement is straightforward at BMW Baku
- Brake system: G11 7 Series uses electric parking brake with integrated service mode — requires BMW diagnostic equipment for rear pad changes
- Transfer case (xDrive): fluid change at 60,000 km recommended to maintain smooth AWD engagement
- Executive Drive Pro (if fitted): front/rear roll stabilisation actuators — specialist diagnostic required for any ride height irregularities
- Battery management: G11 and G70 use AGM battery systems; replacement must be coded to the vehicle management system
Ownership Cost Estimator (Azerbaijan)
Adjust these values for your driving profile. All figures are estimates for planning purposes only.
- Estimated annual fuel consumption: 1700 L
- Estimated annual fuel cost: $1190
- Total annual ownership estimate: $6690
- Average monthly ownership estimate: $558
- 730i fuel consumption: 7.5–9.5 L/100km in mixed driving — one of the most efficient 7 Series options in real-world conditions
- B48 engine requires full synthetic 0W-30 or 5W-30 BMW Longlife 04 specification oil; RON 95 minimum fuel
- 8-speed ZF transmission: fluid service recommended at 80,000 km for long-term reliability
- Air suspension compressor: budgeted maintenance item on G11 examples above 100,000 km
- The 730i carries near-identical insurance and road tax liability to the 740i in most Azerbaijani registration categories — verify before purchase
Used 730i Buying Checklist
Inspect each point thoroughly before committing to a purchase. Request service records, VIN validation, and any recall completion documentation.
- Air suspension operation: check all four corners are level at startup and that the system rises and lowers correctly through the range
- B48 engine: check for any oil leaks at the rocker cover and turbo oil feed lines — these are manageable but indicate service history quality
- Service history: verify BMW Baku or authorised dealer stamps; the B48 is sensitive to oil change intervals
- Infotainment system: test all iDrive functions including navigation, wireless connectivity, and driver assistance cameras
- Rear entertainment or Executive Lounge (if specified): confirm all rear screens, ambient lighting zones, and massage seats function correctly
- Exterior lighting: LED adaptive headlights are standard — confirm all units illuminate correctly and directional function operates
- Transmission behaviour: test smooth engagement at low speed and clean kickdown from highway speeds — ZF 8-speed should be imperceptible
- Tyre condition and wheel alignment: large 18–20 inch wheels on 730i are sensitive to kerb damage given the low-profile options specified
730i FAQ — Azerbaijan Buyers
Is the 730i four-cylinder engine suitable for a flagship saloon?
For the majority of real-world 7 Series use, yes. The B48 produces 258–286 hp with 400 Nm of torque available from very low in the rev range, making urban and motorway driving smooth and effortless. The engine's refinement in the sound-insulated 7 Series cabin is impressive — four-cylinder character is well suppressed. Buyers who regularly carry passengers at full capacity over long distances or who value the effortless cruise of a larger-displacement engine will prefer the 740i, but for typical single or paired occupancy use the 730i is entirely appropriate.
How does the 730i compare to the 740i in everyday use?
The cabin, technology, and chassis equipment are nearly identical — both use the same air suspension, iDrive generation, and interior architecture. The 740i provides noticeably stronger mid-range pull, especially above 120 km/h, and has a marginally more prestigious sound. The 730i is lighter, more fuel-efficient, and less expensive to purchase. On paper the gap is meaningful; in practice, on the roads between Baku and Ganja for example, most drivers would not find the 740i's extra performance relevant more than occasionally.
Are spare parts and service readily available in Azerbaijan?
BMW Baku maintains stock for the full G11/G70 range including standard service items for the B48 engine. The B48 is BMW's highest-volume engine globally and parts are well-supported. Air suspension components and iDrive electronics can be ordered through the official dealer, though lead times of 1–2 weeks apply for non-stock items. Specialist independent workshops in Baku have also accumulated experience with the G11 platform as the generation ages.
Should You Buy the BMW 730i?
The BMW 730i makes a compelling case that few buyers pause to consider: you receive every flagship 7 Series comfort, technology, and exterior statement that the range offers, with a turbocharged four-cylinder that is efficient, refined, and well-supported. The price gap to a 740i is real. For buyers in Azerbaijan who want 7 Series presence without 740i running costs, the 730i is a rational and underappreciated choice. Source a low-mileage G11 example with full BMW history and you will have one of the most characterful luxury saloons in Baku for the money.
