What's the difference?
Tim Robson road tests and reviews the BMW 4 Series with specs, fuel consumption and verdict at its Australian launch.
Following on from the mid-life tweaks to BMW's mainstay 3 Series in December 2015, the spin-off 4 Series line has now been updated along the same powertrain and equipment lines.
Based on the same mechanicals as the 3 Series, the three-year-old 4 Series was ostensibly formed to give BMW's nomenclature some sense of logic by designating its two-door machines as 'evens' (2 Series, 4 Series and 6 Series) and its four-door cars as 'odds'.
Three variants currently make up the 4 Series range, including a two-door Coupe, a two-door Convertible and – oddly, given the naming regime – a four-door Gran Coupe that also sports a hatch-like tailgate.
The venerable VW Caddy was launched in 1979 and after five generations and more than four decades of service, it remains one of the world’s most popular range of small vans.
In Australia’s light-commercial vehicle market, the Caddy’s work-focused Cargo model competes in the small van (under 2.5-tonne GVM) segment against the Renault Kangoo and Peugeot Partner.
The VW range offers Cargo (SWB), Cargo Maxi (LWB) and Crewvan (LWB) models with a unique choice of petrol/diesel engines and manual/auto transmissions.
We recently revisited this German workhorse to find out why it remains such a strong seller in Australia from a business perspective.
The 4 Series line offers three distinct points of difference from the more traditional 3 Series, each with their own attraction. The sharpening of the sticker prices and the additional spec helps their cause as well, with the 430i Coupe probably our pick of the range. The 440i is the firecracker of the group, while the 420d is also worth a look, thanks to its value and prodigious torque output.
It’s not hard to see why the Caddy Cargo maintains its enduring favouritism in the small van class. It has outstanding workhorse capabilities, unmatched five-star safety and drivetrain choice, combined with a spirited car-like driving experience, be it unladen or with a heavy payload. It’s not perfect, but it's also hard to fault in a workhorse role.
No external changes to the 4 Series' bodywork have been affected for this midlife refresh, but there have been plenty of tweaks to the standard equipment offerings right across the board.
Our test vehicle rides on a 2755mm wheelbase with 4500mm overall length, yet its 11.4-metre turning circle is slightly larger than a Toyota HiAce mid-sized van, which highlights the restrictions in steering lock shared by front-wheel-drive vehicles like the Caddy and its French rivals.
Underneath you’ll find robust MacPherson strut front suspension, a coil-spring beam rear axle with Panhard rod, four-wheel disc brakes and electric power-assisted steering.
It comes well armoured for work duties with unpainted dark grey plastic used in areas where bumps, scrapes and wear usually occur like the front/rear bumpers (including the rear pillars from top to bottom), door-handles and door mirror-shells. The bright silver alloy-look plastic wheel-covers can also be easily replaced if damaged by kerbs to keep this van looking sharp on the job.
Its purposeful external appearance is matched by a neat and practical cabin design with wipe-clean rubber flooring and fabric-trimmed bucket seats for driver and passenger. Hard surfaces abound in contrasting shades of grey with splashes of satin chrome.
The minimalist dash design is achieved by corralling most functions into the comparatively small (by today's standards) central touchscreen including often-used climate control, engine auto start-stop etc., which can be fiddly and distracting when driving. Thankfully, at least physical dials for audio volume and tuning remain.
Two-doors are never the most practical devices, but the 4 Series Coupe and Convertible duo make a decent fist of it for front-seat passengers. There are bottle holders in both doors and a pair of cupholders in the centre console, along with a large lockable glovebox.
The centre bin is, however, quite shallow, and houses the car's single USB port inside it. There is covered storage under the dash for smaller items, and a small rubber-lined tray that the current crop of phones has outgrown.
The rear seating in the Coupe is reduced to almost a formality, especially if the front seat passengers are tall and the front seats are set back, while the sloping roofline reduces head space quite considerably. A centre armrest contains a pair of cupholders, and there are small side pockets.
Rainy conditions precluded us from trying the Convertible's metal folding roof, but the rear seat space restrictions also apply here. Its 370 litres of boot space is roomy enough for a drop-top, while a clever lifting function raises the folding roof structure up by about 300mm to allow luggage to be stowed under the panels when the roof is down. Capacity drops, though, to just 230 litres.
The Gran Coupe, on the other hand, is the most practical car in the entire 3 and 4 Series line-up outside of the 3 Series Touring wagon. With a large, flat load area, and a hatch-like tailgate, the Gran Coupe can swallow 480 litres of gear with the seats up and an impressive 1300 litres with the seats lowered.
Face-level rear vents, more head and backseat legroom – not to mention the fact you don't have to squeeze into the rear past the front seat – makes the Gran Coupe a most useful device, and it's little wonder it's the most popular variant of the three.
The Caddy’s 1508kg tare weight and 2250kg GVM results in a 742kg payload rating, of which up to 100kg can be legally carried on the roof where external anchorage points are provided for roof racks or rails.
It’s also rated to tow up to 1500kg of braked trailer, although its relatively low 75kg tow-ball download (TBD) limit could present a challenge, given that TBD is typically about 10 per cent of trailer weight. So, a 150kg TBD rating would be better.
Volkswagen also does not publish a GCM (Gross Combination Mass) rating, so we don’t know how much it can legally carry and tow at the same time.
The cargo bay, which offers up to 3.1 cubic metres of load volume, is accessed through a kerbside sliding door or asymmetric rear barn-doors.
Its 1797mm length and 1614mm width with 1230mm between the rear wheel-housings provides good versatility, given it can carry an 1165mm-square Aussie pallet or 1000 x 1200mm Euro 3 pallet, two 800mm x 1200mm Euro pallets, or two 720 x 830mm bread-roll containers.
However, with the sliding side-door’s 695mm opening, all of these would need to be loaded through the rear barn-doors which offer 180-degree opening for easy forklift or loading dock access. The load floor is protected by a thick moulded-rubber liner and there are six load-anchorage points.
The cargo bay walls and doors are lined to mid-height and there are two bright LED roof lights and a handy 12-volt socket.
Driver and passenger have ample cabin storage with large-bottle holders and bins in each front door, a handy pull-out compartment to the right of the steering column, numerous bins embedded in the dash-pad, full-width overhead shelf, a large glovebox and a centre console with dual small-bottle/cup holders and numerous storage nooks.
Entry into the 4 Series world now stands at $68,900 plus on-roads for the petrol 420i Coupe and Gran Coupe, and tops out at almost $118,000 for the 440i Convertible.
Both the 420i and 420d have been boosted by the addition of adaptive M dampers, a heads-up display, powered folding rear-view mirrors, lane-change warning, driving assistant and BMW's surround view camera with top and side views.
BMW claims the extra kit is worth just over $8000. Leather seats, sat nav, BMW's ConnectedDrive Emergency call system, bi-Xenon headlights and reversing camera are also featured. An eight-speed automatic transmission is offered as stock, but a six-speed manual can be optioned at no cost.
The diesel version costs an additional $2200 over the petrol powerplant.
Stepping into the 430i, the M Sport Package is offered as standard, with the Luxury line, which includes a leather-trimmed dash, a no-cost option.
Additional standard equipment over the outgoing 428i includes 19-inch M rims, heads-up display, lane change warning, driving assistant and surround view camera. The 430i also gains electric lumbar support for driver and front passenger seats and a nine-speaker stereo system over the base 420i.
Finally, the range-topping 440i scores a heads-up display, lane change warning, driving assistant, surround view camera, adaptive LED headlights, leather dash, front seat heating, high beam assist, active cruise control with stop and go function and parking assistant over the outgoing 435i.
Over the 430i, the 440i also gets variable sport steering, a Harman/Kardon surround sound system with 16 speakers, a leather instrument panel (with M Sport Package), ConnectedDrive internet and concierge service, and air collar neck-warming ducts for the 440i Convertible.
Our test vehicle in standard Candy White is the Cargo SWB, which at entry-level is available with a 1.5-litre turbo petrol engine with six-speed manual or seven-speed auto. Or you can step-up to a 2.0-litre turbo-diesel with either a six-speed manual or (like our example) a seven-speed auto for a price of $45,990 plus on-road costs.
That’s higher than its two small van competitors, given the Renault Kangoo SWB petrol auto lists at $42,990 and Peugeot’s Partner Pro Short petrol auto is $39,990, but the Cargo is unique in offering five-star safety and its drivetrain choices.
The work-focused standard equipment list includes 16-inch steel wheels with plastic covers, 205/60R16 tyres and a full-size spare. There’s also an electronic handbrake, separate cargo bay locking system, a reversing camera, rear parking sensors, heated door mirrors, daytime running lights, two USB-C ports and two 12-volt sockets.
A moulded composite bulkhead with window separates the cabin from the cargo bay. The driver also gets a leather-trimmed flat-bottom steering wheel with multi-function controls, plus adjustable lumbar support for both driver and passenger seats.
The four-speaker multimedia system is controlled by an 8.25-inch colour touchscreen with Apple CarPlay, Android Auto and MirrorLink connectivity and FM radio, but no DAB or (sorry, talkback fans) AM band.
Volkswagen also offers numerous paint colour options and four option packs, plus there’s a genuine accessories range containing useful workhorse items like all-weather floor mats, roof racks, cargo barriers, dashcams and more.
There are two new petrol engines, two new badges and prices cuts of up to $10,000 right across the board for the line-up, along with additional standard equipment that improves the value equation even further.
The line kicks off with the 420, which can be had in either diesel or petrol guise. The 420i gains BMW's new B48 2.0-litre four-cylinder turbo petrol engine, which gains 5kW over the old motor to produce 135kW and 270Nm.
It also benefits from slightly improved fuel economy, with a drop of 0.3 litres per 100km for the Coupe and 0.5 for the Gran Coupe to 5.8L/100km, and a fall of 0.2L for the Convertible to 6.2L/100km.
The 420d retains its 140kW, 400Nm 2.0-litre four-cylinder turbo diesel engine, which returns 4.3L/100km in the fixed roof cars and 4.7L/100km for the Convertible.
The 430i – formerly known as the 428i – also receives the new 2.0-litre petrol engine, albeit in a 185kW/350Nm tune. Its fuel economy drops a healthy 0.6L for the Coupe and Gran Coupe and 0.4L for the Convertible, posting figures of 5.8 and 6.3L/100km respectively.
The top-spec 435i has been transformed into the 440i with the addition of BMW's new Twinpower 3.0-litre straight six petrol motor. Its output jumps 15kW to 240kW and by 50Nm to 450Nm, and its consumption falls by more than half a litre to 6.8 litres per 100km for the closed-roof pair and 7.2L/100km for the Convertible.
All cars come standard with a 'traditional' ZF eight-speed torque converter automatic transmission with steering wheel paddles as standard fitment, while a six-speed manual gearbox is a no-cost option across the line.
Our test vehicle’s premium 2.0-litre four-cylinder turbo-diesel engine, dubbed TDI320, meets Euro6 emission standards using AdBlue, and produces 90kW at 4250rpm and 320Nm between 1500-2500rpm.
The seven-speed dual-clutch automatic offers three drive modes comprising (default) Drive, Sport or sequential manual-shifting using steering wheel-mounted paddles. There’s also an electronically-controlled automatic locking diff.
Our brief test loop on a rainy, blustery Melbourne winter's day in all three model types (but no diesel) netted varying fuel consumption readings across the line; we recorded 8.4L/100km in a 420i sedan against a claimed figure of 5.8, 9.8L/100km for the 430i Gran Coupe against a claimed figure of 5.8L/100km, and 8.4L/100km against the 440i Gran Coupe's 6.8L/100km.
The official combined average fuel consumption is a hybrid-like 4.9L/100km and the dash display was showing 5.6L after our 355km test, of which about one third of that distance was hauling a near-maximum payload.
That wasn’t far south of our own fuel-sipping figure of 6.5L/100km, based on actual tripmeter and fuel bowser readings. Therefore, you could expect an excellent real-world driving range of up to 770km from its 50-litre tank.
BMW introduced a raft of tweaks to the 3 Series platform late last year, which have translated over to the 4 Series. The key addition across the line is BMW's two-stage adaptive dampers that feature a Sport and a Comfort circuit, fitted as part of the M Sport pack that comes standard on the 430 and 440, and is a $2600 option on the 420.
Larger 19-inch rims are fitted to the 430i and 440i cars, while the 420 gets 18s out of the box. It's possible to fit 18s on the more expensive cars, as part of the no-cost Luxury option pack that supplants the standard M Sport pack.
While our test was brief and held in less than ideal road conditions, the large-wheeled 4 Series really didn't enamour themselves to this author. There's a distinct lack of communication from the tyres and chassis through the steering wheel and your backside, while the combination of firm Sport shocks and large 19-inch wheels with narrow-section tyres made for an uncomfortable ride over country roads.
Sampling a 420i with the Luxury 18-inch rims, however, improved things immensely, with much better feedback and comfort that didn't come at the expense of handling.
One of BMW's strong points should be its steering, given all the 3 and 4 Series cars are still rear-wheel-drive… but it's not, unfortunately. The electrically assisted set up is far from perfectly calibrated, feeling too dull and digital underhand, no matter what the setting.
The pick of the bunch performance wise is – logically – the six-cylinder 440i. The turbo powerplant is potent from right down the rev range, with a muted yet still pleasing engine note permeating the cabin. The self-shifting mode on the eight-speed auto does a good job of keeping up as well.
The updated 2.0-litre four is a sprightly performer, too.
Its compact external dimensions are deceptive, as the cabin has ample headroom and it’s not hard for even tallish drivers (I’m 186cm) to find a comfortable position, even though the close-fitting bulkhead restricts backrest recline adjustment and the base cushion rake is fixed.
Small vans are the closest you’ll get to a car-like driving experience in light commercials and, given the Cargo’s unique turbo-diesel powertrain, it has unmatched torque output that provides energetic performance.
The shift calibrations of its seven-speed dual-clutch automatic ensure vigorous response in city and suburban driving, given that for most of the time they keep the engine operating between 1500-2500rpm, where its 320Nm of torque is served at full strength.
Combined with nicely weighted steering and four-coil suspension that provides an ideal balance of responsive handling and supple bump absorption, it’s an enjoyable and engaging vehicle to drive. The Sport drive mode and sequential manual-shifting options raise the fun level.
The gearing also ensures low-stressed highway driving with only 1600rpm required to maintain 110km/h, at which speeds the solid bulkhead minimises cargo bay noise that mostly emanates from the rear tyres. However, tyre noise can still be intrusive on certain grades of coarse bitumen.
To test its payload rating, we forklifted 650kg into the cargo bay through the rear barn-doors, which with driver equalled a total payload just shy of its 742kg payload limit. The rear suspension compressed almost 60mm under this weight, with long jounce rubbers positioned inside the rear coil springs providing additional load support and, in effect, a second stage of springing.
The Caddy took this heavy load haul in its stride on city and suburban roads, gliding over bumps without a hint of bottoming-out. The payload’s effect on engine, steering and braking performance was minimal and its handling composure was maintained regardless of speed or road conditions.
It also made light work of our 13 per cent gradient, 2.0km-long set climb at 60km/h, and although engine braking on the way down required some assistance from the quartet of disc brakes to keep speeds in check, they handled this task with ease.
Our only criticism of the driving experience is that, given the substantial blind-spot over the driver’s left shoulder caused by the cargo bay’s solid walls, a Cargo buyer must pay extra to get blind-spot monitoring and rear cross-traffic alert as part of an options pack. We reckon these active features are crucial to safe van operation (any solid-walled van that is) and should be standard.
six airbags, lane departure warning, pre-collision safety pack, parking sensors, active cruise control with collision warning, AEB and pedestrian warning, along with reversing camera and surround-view cameras across the line.
Unmatched by its small van rivals is a five-star ANCAP rating (tested 2021, expires 2027) which applies to all Cargo variants built from July 2022.
It’s equipped with seven airbags, AEB with pedestrian and cyclist monitoring, a reversing camera, rear parking sensors, daytime running lights, non-adaptive cruise control, driver fatigue alert system and more, but you must pay extra for extra safety.
BMW offers a Service Inclusive program at the time of purchase, which for $1340 covers everything – including items like spark plugs, brake fluids and other fluids - for five years or 80,000 km scheduled. The cars are also covered by a three-year free roadside servicing program, in addition to BMW's two year, unlimited kilometre warranty.
The Caddy comes with a five-year/unlimited-kilometre warranty and 12 months roadside assist.
Scheduled servicing is every 15,000km or 12 months, whichever occurs first.
An optional five-year pre-paid service package is available for the price of a three-year package ($2000), so that’s two free services and savings of up to $1439 compared to pay-as-you-go capped-price servicing. In other words, an average annual servicing cost of $400.
