These are a initial cinema of a next BMW 3 Series in Touring form, display how a many unsentimental several of a G20-generation automobile will demeanour when it hits roads in 2019.
Both a Touring and tavern versions of BMW’s future model are being engineered to offer even some-more comfort yet not to a wreckage of handling. This means a whole operation — even sportier versions such as a just-spotted M Sport several — should be some-more forgiving on severe surfaces than before.
The proclivity for this more gentle indication comes from prohibited foe from Mercedes-Benz and a rivalling C-Class. Although a 3 Series stands clever as BMW’s best-selling model, it’s fallen short of a hot-selling C-Class, that sole in 176,915 units to a 3 Series’ 129,053 in 2017.
As such, BMW engineers have been tasked with broadening a 3 Series’s strech and fighting a C-Class during a own, some-more comfort-focused game.
The destiny 3 Series will also be offering with some-more variants, including new M-fettled versions that underline inexhaustible boosts in performance.
The initial several will be a rear-wheel-drive M340i M Performance, that will underline a 360bhp chronicle of BMW’s twin-scroll turbocharged 3.0-litre inline six-cylinder petrol engine. It will be followed by a four-wheel-drive M340d xDrive M Performance, that is set to accept a 320bhp chronicle of a company’s twin-turbocharged 3.0-litre inline six-cylinder diesel engine.
Key to a enlargement devise for a seventh-generation 3 Series is a further of dual new M Performance models powered by six-cylinder engines. In a plan mirroring that undertaken with a latest 5 Series, a new M Performance variants will go on sale shortly after some-more mainstream versions of a new 3 Series are launched in both tavern and estate bodystyles. The new derivatives will be offering as possibly a petrol or a diesel and will overpass a opening in a choice that currently exists between customary six-cylinder models and BMW M’s range-topping M3 saloon.
The new performance-oriented 3 Series models will be targeted during a likes of a Audi S4 quattro and Mercedes-AMG C43 4Matic. They will have particular styling touches, their possess singular framework tuning and comparatively high apparatus levels. Autocar can exhibit they will also form the basement for a two-door M440i M Performance Coupé and M440d M Performance Coupé models, that will arrive in showrooms in 2020.
Significantly, a preference to launch a M340d xDrive M Performance indication underpins skeleton by BMW to continue to supply a 3 Series with a full operation of three, four and six-cylinder diesel engines, notwithstanding increasingly parsimonious emissions legislation opposite Europe, including a spook of informal bans on diesel cars from entering city centres (some of that might be implemented in Germany).
“The diesel is a vicious member in a efforts to strech a 2020 meridian targets,” pronounced BMW authority Harald Krüger. “It is really critical in improving a altogether potency of a destiny models.”
BMW is pulling out all a stops to safeguard a new 3 Series, that goes underneath a inner codename G20, possesses a stylistic appeal, opening credentials, energetic ability and altogether technical bravery it needs to scratch behind a gains done by a keenest executive category rivals, many particularly a C-Class, that officials have described to Autocar as a transparent benchmark.
Prototype tavern versions of a new 3 Series spied contrast on a roads around BMW’s engineering domicile in Munich recently prove it will continue a company’s tradition of evolutionary pattern change, with an coming that leans heavily on that of a incomparable 5 Series, as good as change from a X2 SUV. The automobile has a some-more naturally sporting position to counterpart a changes beneath.
Credit for a pattern of a new indication rests with former BMW code pattern boss, Karim Habib, who changed to Infiniti last year.
As a initial 3 Series indication to be entirely honed in BMW’s Munich-based breeze tunnel, a G20 is also claimed to compare a aerodynamic potency of a 5 Series. The many sleazy physique character is pronounced to have a drag co-efficient of 0.22.
The new 3 Series has grown in many pivotal dimensions. Nothing is official, yet Munich insiders advise altogether length is adult by 60mm to around 4703mm. Some 20mm of this is pronounced to be strong within a extended wheelbase, that has increasing to roughly 2830mm, adult from 2810mm. By comparison, a stream C-Class is 4696mm in length and has a 2840mm wheelbase.
The new 3 Series is formed on BMW’s latest CLAR (cluster architecture) height — as used by all new BMW models — and facilities a longitudinally mounted engine. In gripping with developments already seen on a incomparable 5 Series, it advantages from a operation of weight-saving initiatives, including a incomparable use of hot-formed high-strength steel within a categorical physique structure, to cut a already rarely rival kerbweight of today’s sixth-generation indication by adult to 50kg, notwithstanding a incomparable dimensions.
The volume of 3 Series sales manners out a use of carbonfibre, so there’ll be no Carbon Core constructional developments like those seen on a headlining 7 Series.
However, BMW’s physique construction specialists advise a G20 will underline a many incomparable array of expel aluminium components and a incomparable commission of magnesium in load-bearing areas. All told, a weight-saving developments are approaching to give a lightest several in a range, a three-cylinder 318i, a kerb weight of about 1425kg.
Together with a rebate in weight, a CLAR height is also claimed to pierce an alleviation in constructional acerbity that, in a pierce identical to that undertaken with a 5 Series, forms a basement for a change in truth for a framework tuning. Recognising a flourishing patron enterprise for additional float comfort, BMW is looking to yield customary versions of a new 3 Series with some-more agreeable properties, in a pierce directed during relating a fibre of a C-Class.

Expected developments embody a adoption of back atmosphere springs on some-more upmarket models. However, BMW is suspicion to have ruled out a active four-wheel steering complement (that countersteers a back wheels during revoke speeds and together steers them during aloft speeds in a name of agility), even yet a 5 Series is versed with it.
In a delay of a Efficient Dynamics programme that has seen unbroken reductions in expenditure and emissions opposite a 3 Series choice over new years, BMW skeleton to pierce a array of upgrades to a petrol engine choice of a new model.
BMW officials have confiredm an prolongation of a plan in use today, with both 3 and four-cylinder units portion volume-selling 316i, 318i, 320i and 330i models in multiple with either standard rear-wheel expostulate and discretionary xDrive four-wheel expostulate on comparison variants.
Positioned above them will be a six-cylinder engine offering in both a standard, rear-wheel expostulate 340i and a aforementioned M340i M Performance guises.
BMW has begun to constantly upgrade the petrol engines in any of a several indication lines, with a recently suggested 2 Series Active Tourer facelift being a many new indication to bear the tweaks. Measures such as a new injection system, a particulate filter to revoke NOx levels, a revised belt expostulate complement and some-more fit cooling measures are claimed to pierce assuage increases in energy and torque.
Together with a rebate in kerb weight betrothed by a new CLAR underpinnings, a reworked petrol units are also pronounced to offer expenditure and glimmer assets of adult to 5% opposite a indication line-up.
Unclear during this theatre are BMW’s skeleton to deliver H2O injection as partial of a raft of revisions. First introduced on a six-cylinder section used by a M4 GTS, and also tested by Autocar on a antecedent chronicle of a smaller three-pot section propitious to a 118i, a H2O injection complement brings proven opening and potency gains. However, it also requires a further of a H2O tank tighten to a engine, that in spin complicates packaging.
Accompanying a petrol units will be operation of diesels. Adopting developments initial seen on a 2.0-litre section used by today’s 325d, any new oilburner will accept two-stage turbocharging and a resourceful catalytic rebate (SCR) filter as partial of BMW’s efforts to revoke emissions.
At a same time, BMW skeleton to boost a vigour of a common-rail injection complement used by any of a diesel engines from 2000 to 2200 bar in a smaller three-cylinder units and from 2000 to 2500 bar in a four-cylinder engines, with a difference of a section to be used by a new 325d, that will run pressures of adult to 2700 bar.
Autocar’s sources advise a 1.5-litre three-cylinder powered 316d will benefit 21bhp during 136bhp, instead of a 115bhp of today’s model. Above it, a 2.0-litre four-cylinder will continue to be offering in 3 graphic states of tune, building an combined 13bhp in a 318d during 163bhp, some 14bhp some-more in a 320d during 204bhp and a claimed 14bhp additional in a 325d during 238bhp.
The Bavarian manufacturer is also formulation to supply adult to 3 new 3 Series variants with an upgraded chronicle of today’s 3.0-litre inline six-cylinder diesel. They embody a customary 330d and 340d, as good as a aforementioned M340d xDrive M Performance diesel flagship.
The stream 3 Series saloon, designated F30, has been on sale given 2012, and a 4 Series (F32) coupé given 2013.
