The BMW 3 Series LWB has appeared on China’s MIIT Batch 413 as the eighth-generation long-wheelbase sedan, internally coded G58. Gasgoo’s November 6, 2026 English analysis of the list released on November 3 frames it as the first New Class design language on a domestically produced BMW internal-combustion sedan.
Two petrol variants are declared: 325L and 330L, both with 2.0-litre turbo engines. Overall length is 4,865 mm, width 1,852 mm, height 1,461 mm and wheelbase 2,970 mm. China market launch is expected in 2027. India import or localisation plans are not part of this filing.
Here is what the MIIT paperwork confirms, how naming now splits ICE from battery-electric 3 Series models, and what still needs an official BMW China reveal.
What is the BMW 3 Series LWB G58?
The BMW 3 Series LWB G58 is the China long-wheelbase edition of the next-generation 3 Series. Gasgoo describes it as the debut of BMW’s New Class design language on a domestically built ICE sedan, not a battery-electric model. That matters because New Class branding has been closely tied to BMW’s electric roadmap elsewhere.
Up front, the kidney grille narrows horizontally and merges with the headlight clusters. Daytime running lights move to a vertical layout, which Gasgoo says officially retires the round “Angel Eyes” look. The body keeps a classic sedan silhouette with semi-hidden door handles. At the rear, slender full-width taillights sit beside symmetrical rectangular exhaust outlets.
Those exterior cues matter because they show New Class design arriving on combustion metal, not only on battery-electric concepts. Shoppers who follow BMW’s electric New Class cars should not assume every New Class surface equals a pure-electric powertrain in China.
Interior localisation details for the domestic version still await official disclosure. Treat cabin screens, materials and option packs as unconfirmed until BMW Brilliance publishes launch materials. The same caution applies to driver-assistance hardware: the Gasgoo section used here does not list lidar counts or software packages for the G58 ICE sedan.

Those power and dimension figures come from Gasgoo’s English breakdown of MIIT’s 413th vehicle list. Rated power and maximum net power are both listed in the filing language Gasgoo quotes; do not collapse them into a single “horsepower” claim without noting which figure you mean.
How big is the new BMW 3 Series LWB versus the current one?
Gasgoo says the new long-wheelbase car is larger than the current China LWB, but the growth is restrained: 27 mm more length, 25 mm more width and 9 mm more wheelbase. That keeps the car recognisably in the mid-size sports-sedan envelope rather than stretching it into a different class.
| Dimension | G58 LWB | Change vs current China LWB |
|---|---|---|
| Length | 4,865 mm | +27 mm |
| Width | 1,852 mm | +25 mm |
| Height | 1,461 mm | Not stated as a delta in the Gasgoo piece |
| Wheelbase | 2,970 mm | +9 mm |
Rear-seat space is the usual reason BMW sells a dedicated China LWB. The filing numbers support a modest stretch, not a radical rethink. Exact knee-room, rear screen size and seat-track travel still need a launch walkthrough.
Why did BMW drop the “i” badge on the ICE 3 Series LWB?
Gasgoo’s reading of the filing is clear: the combustion edition drops the “i” suffix from the trunk badge and retains only the “L” designation. The “i” prefix is formally ceded to pure-electric models, completing a clean split in the naming hierarchy.
For shoppers, that means a future China ICE 325L or 330L should not be confused with an i3 or other battery-electric sibling that may share New Class design cues. Sibling and reference names should stay labelled as such until BMW publishes the full China line-up map.
The same Batch 413 catalogue also carries high-power EV filings such as the 2027 Zeekr 001 MIIT filing with a 370 kW single-motor layout and the Denza N9 EV MIIT tri-motor filing.
How much power do the 325L and 330L make?
The 325L uses a 2.0-litre engine with 172 kW rated power and 155 kW maximum net power, with a top speed capped at 233 km/h. The 330L steps up to 211 kW rated and 190 kW net, with a 250 km/h top speed.
Those are MIIT filing figures summarised by Gasgoo, not a full dyno sheet or India ARAI certificate. Transmission type, drive layout and any mild-hybrid assistance are not detailed in the Gasgoo section we used for this article, so leave them unmarked rather than guessing.
For context, the net-power step from 155 kW on the 325L to 190 kW on the 330L is the clearest on-paper differentiator between the two petrol filings. Top-speed caps of 233 km/h and 250 km/h follow the same ladder. Real acceleration, fuel economy and India-cycle numbers would still need homologation sheets that do not exist for this China filing.

Will the BMW 3 Series LWB G58 come to India?
BMW has not announced an India plan for the G58 long-wheelbase car. The confirmed story today is a China MIIT filing with an expected 2027 domestic launch window. India would still need pricing, homologation, right-hand-drive decisions if applicable, and a clear CBU-versus-local path.
Until those appear, treat the G58 LWB as a China-market product that signals how BMW will split ICE and electric 3 Series naming. Readers comparing mid-size cars should wait for BMW India or BMW Group statements before assuming a showroom date.
Historically, China LWB 3 Series cars have not automatically translated into India CBU or local assembly programmes. A New Class design language shared with future electrics also does not, by itself, create an India EV or ICE launch calendar.
CarBike Insight Analysis
The G58 filing is interesting less for raw millimetres and more for the naming clean-up. Putting New Class design on a China ICE sedan while handing the “i” badge to BEVs reduces badge confusion that has grown as electrified and combustion models share showrooms.
The open questions are China price bands, whether 325L and 330L cover the whole ICE ladder at launch, and whether any New Class ICE hardware later influences export markets. A restrained 27 mm length gain suggests BMW is refining the China LWB recipe rather than chasing a different segment, which usually means cabin polish and software will decide showroom success more than millimetres alone.
Our view: for China shoppers, the restrained dimension growth plus clearer ICE-versus-BEV badging looks coherent on paper; for India readers, this remains a distant filing signal, not a purchase brief. The next proof points are BMW Brilliance launch pricing, a full option sheet, and any homologation chatter outside China.
FAQ
What is the BMW 3 Series LWB G58?
It is the eighth-generation China long-wheelbase 3 Series ICE sedan filed on MIIT Batch 413. Gasgoo’s November 6 analysis says it brings New Class design language to a domestically produced combustion sedan.
What are the BMW 3 Series LWB dimensions?
MIIT figures summarised by Gasgoo list 4,865 mm length, 1,852 mm width, 1,461 mm height and a 2,970 mm wheelbase—about 27 mm longer and 9 mm longer in wheelbase than the prior China LWB.
How much power do the 325L and 330L make?
The 325L lists 172 kW rated and 155 kW max net with a 233 km/h top speed. The 330L lists 211 kW rated and 190 kW net with a 250 km/h top speed.
When will the BMW 3 Series LWB launch in China?
Gasgoo expects a 2027 China market launch based on current cadence. That is not the same as a priced launch event or a dealer booking window.
Is the BMW 3 Series LWB coming to India?
Not announced. The MIIT filing covers China. Any India plan would need separate BMW India confirmation on import or local assembly, pricing and timing.
