BMW 528i vs Kia Tasman

What's the difference?

Sleek and attractive in the city,  engaging on a country back road and with plenty of clever technology, the 5 Series sedan ticks all the right boxes as an executive express. If you can stomach the price hike, the six-cylinder 540i is our pick of the bunch.

Ute buyers prepared to look beyond the Tasman’s polarising appearance will discover a competent all-rounder. It has its faults like any ute but boasts high standards of engineering, build quality, interior design and performance that make it a worthy new competitor in this space.

Hardly a revolution, the 5 Series has instead undergone a few nips and tucks. But if it ain't broke and all that. It might not be the most head-turning offering, but the 5 Series sedan remains sleek, powerful and understated, and it is undeniably handsome on the road.

Its 8mm wider, 28mm longer and 2mm taller than the car it replaces, but it's also around 95kg lighter, thanks to its aluminium doors and boot and a clever magnesium frame for the instrument panel that saved another two kilograms. There's some other clever design elements, too. The kidney grille has active air flaps that open when extra cooling is required, closing when it isn't, reducing drag and helping accleration.

Inside, the 5 Series offers a beautifully crafted yet joyously understated cabin, with quality materials joining modern technology in a seamless way.

The Tasman is claimed to have more Australian input than any previous Kia model and it certainly has a distinctive ‘Australianised’ competence in the way it performs (see Driving).

It also follows a reassuringly conventional engineering path with its turbo-diesel drivetrain, body-on-ladder-frame-chassis, twin wishbone/coil-spring front suspension, leaf-spring live rear axle, four-wheel disc brakes and electric power-assisted rack and pinion steering.

The Tasman is no shrimp either, as it shares the same 3270mm wheelbase as the market-leading Ford Ranger and is slightly longer and wider.

Work-focused light commercials are often armoured with unpainted plastic in areas prone to bumps and scrapes. The Tasman S 4x2 follows convention here too with dark grey plastic prominent at the front, rear and along the sides, where unusual ‘eyebrows’ are positioned above the wheel-arches which every onlooker we spoke to said looked better in body colour.

The S 4x2 shares the same 206mm ground clearance, 800mm wading depth and approach/ramp breakover/departure angles as its S, SX and SX+ 4x4 siblings. However, they also share a shallow approach angle of only 20 degrees, which is considerably less than its previously-mentioned rival 4x2 models.

The lower ‘spoiler’ section of the front bumper seems largely responsible for this, as it looks too close to the ground and vulnerable to damage from a farmer’s rocky creek-bed crossing or a tradie’s rugged worksite.

The black and grey interior is a functional and spacious design (see Practicality) which looks and feels more upmarket than typical base-model offerings. It has the coolest doorhandles we’ve seen in a ute, which although made of a composite material look like machined steel, complete with a lathe-like knurled finish on the finger-pulls.

There’s also soft-touch surfaces on the door armrests to optimise elbow comfort plus contrasting hard-surface finishes including honeycomb and diagonal patterns, two-tone fabric seat trim with exposed stitching and neat embossed grooves across the seat-facings.

This is a full-size sedan, and every seat feels spacious and airy. The sloping, slightly coupe-style roofline does cut into headroom in the back, but human-sized people will have little trouble, even sitting behind a tall driver.

Each trim offers two cupholders in the front, with another two housed in a pull-down divider that seperates the rear seat. And there's two ISOFIX attachment points, one in each window seat in the back. 

The 5 Series' boot opens to rival a surprisingly sizeable storage space, offering 530 litres with the 40:20:40 rear seats in place.

With its 2126kg kerb weight and 3250kg GVM, our test vehicle has a mighty 1124kg payload rating which is the largest available in the Tasman fleet. And up to 100kg of that can be carried on the roof.

Like its 4x4 siblings, the 4x2 model is rated to tow up to 3500kg of braked trailer but with its 6200kg GCM (or how much it can legally carry and tow at the same time) the payload would need to be capped at 574kg (a reduction of 550kg) to avoid exceeding the GCM.

Although few (if any) owners would need to tow 3500kg, it’s important to be aware of these numbers if you did to avoid overloading. Even so, almost 600kg of payload would still allow for a crew of five and their gear when towing the maximum trailer weight, so this is a useful set of numbers for many working roles.

Internally the load tub is 1573mm long, 1600mm wide and 543mm deep with a load volume exceeding 1.3 cubic metres. And with 1186mm between the rear wheel-housings, it can carry either Aussie or Euro pallets.

The tailgate can be opened remotely and its hinges provide opening/closing assistance. There’s no standard tub-liner but it comes with four load-anchorage points positioned at around mid-height.

There’s ample cabin space for the driver and front passenger plus storage including a bottle-holder and bin in each door, a single glovebox and a centre console with a large open tray at the front with USB-C ports, two cupholders in the centre and a large box at the back with an internal 12v socket and padded lid which doubles as a comfy elbow rest.

Rear cabin access is enhanced by doors that open to almost 90 degrees and Kia claims the rear bench seat offers best-in-class legroom, headroom and shoulder-room. Even so, it would still be a shoulder squeeze for three big Aussies (like all dual cabs short of a full-size US pick-up) so a limit of two would be preferable for long trips.

Rear storage includes a bottle holder and bin in each door plus pockets on the front seat backrests and a slender pocket on the rear of the console ideal for storing phones. A couple of USB ports would be handy here too, but we are talking base-grade.

There’s also no fold-down centre armrest at this level but the bench seat's 60:40-split base cushions can swing up and be stored vertically if more internal cargo space is required, or to access a full-width bin that can store heaps of stuff away from prying eyes.

The Kia Tasman range offers a choice of cab-chassis and ute body styles and five model grades comprising S, SX, SX+, X-Line and premium X-Pro.

Our S 4x2 test vehicle represents the bottom rung of the model ladder, for those not needing the all-terrain capabilities of its S 4x4 sibling and other Tasman models. However, it does share the same 2.2-litre four-cylinder turbo-diesel and eight-speed automatic transmission, for a list price of $42,990.

That's more than competitive with equivalent dual-cab ute rivals like the Ford Ranger XL Hi-Rider 2.0L auto 4x2 ($43,530), Toyota HiLux Workmate Hi-Rider 2.4L auto 4x2 ($44,820) and Isuzu D-Max SX High-Ride 2.2L auto 4x2 ($44,200). Our example is also finished in 'Steel Gray' which is a premium paint option that adds $700 to this price.

The S 4x2 comes standard with 17-inch black steel wheels and 265/65 R17 tyres with a full-size spare, automatic LED headlights/daytime running lights/tailgate-mounted rear stop-lights, front/rear parking sensors, rear bumper corner-steps, body-coloured/heated door mirrors, body-coloured doorhandles with pocket lights (front doors only) and more.

Accessing the cabin using the smart key reveals a premium steering wheel and gear knob, remote start, six-way manually adjustable driver’s seat, dual-zone climate control, 12v socket and USB-C ports, tyre pressure monitoring, integrated trailer brake controller, reversing camera and more.

There’s also a six-speaker audio system and what Kia calls the ‘Integrated Panoramic Display’ which in one expansive digital screen combines a configurable 12.3-inch driver’s instrument display, 5.0-inch climate control display and 12.3-inch multimedia touchscreen display.

The hunt for efficiency sees all but the most expensive 5 Series models equipped with four-cylinder engines, including the entry-level 520d, which is fitted with a 2.0-litre diesel unit that will produce 140kW at 4,000rpm and 400Nm from 1,750rpm. That's enough to push the cheapest 5 Series to 100km/h in a not particularly inspiring 7.5 seconds, topping out at 235km/h.

The cheapest petrol, the 530i, arrives with a turbocharged 2.0-litre engine good for 185kW at 5,200rpm and 350Nm from 1,450rpm. That will see you clip 100km/h in 6.2 seconds and push on to a limited top speed of 250km/h.

The turbocharged six-cylinder feels right at home in a car this size, with acceleration effortless and freeway overtaking manoeuvres an absolute breeze.

The 530d introduces the first six-cylinder engine, a 3.0-litre unit that will produce 195kW at 4,000rpm and an impressive 620Nm from 2,000rpm. That's enough to knock off the sprint in in 5.7 seconds and offers a top speed limited to 250km/h.

Finally, the top-spec petrol, the 540i, will produce 250kW at 5,500rpm and 450Nm from 1,380rpm from its 3.0-litre turbocharged straight-six engine. Those are healthy numbers, and enough to welcome 100km/h in a sprightly 5.1 seconds before topping out a limited 250km/h.

Every model is paired with an eight-speed torque converter automatic transmission.

All Tasmans share the same 2.2-litre four-cylinder turbo-diesel that produces 154kW of power at 3800rpm and 440Nm of torque across a 1000rpm-wide band between 1750-2750rpm, which showcases flexibility that's well suited to hauling and/or towing heavy loads.

This engine is paired with an eight-speed torque converter automatic offering the choice of sequential manual-shifting and five selectable drive modes comprising Normal (default), Eco, Sport, Tow and MyDrive with the latter allowing custom settings.

BMW quotes a combined 4.3 litres per hundred kilometres from the 520d, which will also spit out 114g per kilometre of C02. The 530d lifts that number to 4.7 litres per hundred kilometres (which seems a small price to pay for all that extra torque), with C02 pegged at 124g per kilometre. Both diesels get a slightly smaller tank, at 66 litres.

The 530i will sip a claimed/combined 5.8 litres per hundred kilometres, with C02 emissions a claimed 132g per kilometre, while the big 540i requires 6.7 litres per hundred kilometres, with C02 pegged at 154g per kilometre. Both petrol models get a 68-litre tank and require 95RON fuel.

Kia claims combined average consumption of 7.4L/100km and the dash display was showing 8.3 when we stopped to refuel at the completion of our 591km test, which included suburban, city, highway and backroad driving of which about 120km was hauling its near-maximum payload.

Our own figure, calculated from fuel bowser and tripmeter readings, came in higher again at 9.6 which is still within the usual 2-3L/100km discrepancy between lab-based official figures and real-world numbers. That's also excellent sub-10L economy for a vehicle weighing more than two tonnes operating mostly in urban settings.

So, based on our own consumption figure, you could expect a realistic driving range of more than 800km from its 80-litre diesel tank.

BMW's pre-drive briefing was so technology focused we half expected the black turtle neck and dad jean-wearing ghost of Steve Jobs to emerge from behind a curtain clutching an iPad. Only a minuscule portion was dedicated to the cars' drivetrains, with BMW instead hammering home autonomy functions, technology upgrades and the fact that its car was a preview to "the future".

But once we'd slipped behind the wheel of the all-new 5 Series, it all started to make more sense. Having briefly sampled three models (the 530i, 530d and 540i), we can safely report there's nothing particularly revolutionary about their on-road behaviour. That's not necessarily a bad thing - they do everything you could ask of a car in this bracket. They're mostly smooth and always quiet, the new chassis has done nothing to dampen engagement when you start to ask a little more of it, and it's generally a luxurious experience. But then so was the old car.

But what's new is the technology poured into the 5 Series. Every car gets what BMW is calling its personal co-pilot, for example, which is a set of tricky systems (there's six cameras, five radar sensors and 12 ultrasonic sensors scattered around the car) that work with the active cruise control and allow the car to be driven completely autonomous for 30-second intervals. Now, it's not quite as advanced as some of its competitor's systems - it can't change lanes for example - but if you're out on a country road or on a highway, it will stay within its lane, turn around corners and keep up with the traffic, even if they stop in front of you.

This is a full-size sedan, and every seat feels spacious and airy.

While the cheapest diesel model has historically been the best seller, BMW is hoping the new 530i will prove the most popular this time around. And while you couldn't describe it as fast, the power from its four-cylinder engine is ample for all that will likely be asked of it, and it feels sorted and composed on  more challenging roads. It's a smooth and comfortable ride, too, even with the optional 20-inch alloys fitted, though that's undoubtedly thanks to the adaptive dampers and ever-changing dynamic ride function, both of which are fitted as standard. In fact, we're yet to drive a car without those options fitted, so we're forced to reserve judgement on the as-standard ride quality of the cheaper models.

Be warned though, none in the 5 Series range offer the disconnected and perfectly smooth conveyance you might find in some true luxury offerings, and you'll still know when you're diving into deep pockmarks in the road. But the trade off is a an engaging ride and steering set up that always feels planted, with enough feedback to ensure you feel connected to what's happening beneath the tyres. And that's a trade we're more than willing to make.

Step up to the 540i and things take a much sportier turn. The turbocharged six-cylinder feels right at home in a car this size, with acceleration effortless and freeway overtaking manoeuvres an absolute breeze. And while we didn't find roads quite brutal enough to really test the active anti-roll bars housed at each axle, there's a wonderful and stable flatness to the way the biggest petrol handles corners.

It's not cheap, but thanks to the bigger engine and sorted dynamics, the 540i feels most like a 5 Series probably should.

There’s no cabin side-steps but large handles on the A and B pillars assist climbing aboard. People of most shapes and sizes can find a comfortable driving position given its supportive seating, large left footrest and height/reach-adjustable steering wheel featuring a flat top to optimise forward vision and a flat base to provide ample torso room.

It exudes solidity in its engineering and build quality along with excellent steering feel, handling and braking. It also has energetic acceleration and all-round performance.

We trialled the sequential manual-shifting and selectable drive modes but spent most of our test in the ‘Normal’ default setting as it provides the best compromise. It’s also a low-stressed highway cruiser requiring only 1600rpm to maintain 100km/h and little more for 110km/h.

The unladen ride quality is firm, as you’d expect given its big payload rating, but it’s more supple than some other 4x2 one-tonners we’ve tested without loads.

To test its GVM rating we forklifted 890kg into the load tub, which combined with our crew of two equalled a total payload of 1070kg which was only about 50kg below its legal limit.

Under this weight, the large bump-stop rubbers fitted to the rear leaf-springs engaged with the chassis rails above them very early in compression, which eliminated the hard thuds experienced with traditional designs that ‘bottom-out’ over large bumps and through dips.

The Tasman proved to be a competent heavy load-hauler in ‘Normal’ drive mode, maintaining its hearty performance and sure-footed handling with more than one tonne on board.

It also made light work of our 13 per cent gradient, 2.0km-long set climb at 60km/h, self-shifting down to third gear to easily haul this load to the summit.

Engine-braking on the way down, in a manually selected second gear, was equally strong until the engine reached 4000rpm on overrun (no redline is displayed) and promptly shifted up a gear.

These engine-protection protocols are increasingly common in light-commercial vehicles (both utes and vans) but can spring a surprise when you’re ‘leaning’ on the engine to restrain its payload during steep descents and it suddenly shifts up a gear and starts running away from you. Even so, the Tasman’s four disc brakes easily maintained the posted 60km/h speed limit for the remainder of the descent.

Overall, we struggled to find fault in the driving experience apart from one baffling oversight in cabin design, given the steering wheel’s rim blocks the driver’s view of the climate control screen located between the instrument and multimedia screens.

This is distracting for drivers, given climate control settings are among the most-adjusted cabin functions. Hopefully this will be corrected in future upgrades.

The Tasman S 4x2 and X-Line/X-Pro 4x4 models are yet to be ANCAP-rated, but other grades earned the maximum five stars when tested this year.

There’s a full suite of airbags, auto emergency braking (AEB) with multiple object detections, blind-spot monitoring, rear cross-traffic alert, trailer stability assist, driver attention alert, smart cruise control, lane-keeping and lots more.

Junior tradies get ISOFIX and top-tether child-restraint anchorages on the two outer rear seating positions.

The BMW 5 Series is covered by a three year, unlimited-kilometre warranty, and requires condition-based servicing (rather than a pre-defined service interval).

You can also prepay your maintenance costs for five years/80,000kms, with prices ranging from $1,640 for the basic package, and climbing to $4,600 for the all-inclusive option.

It comes with Kia’s excellent seven-year/unlimited km warranty, plus 12 months complimentary roadside assistance which is renewed each year for up to eight years if serviced by an authorised Kia dealer.

Scheduled servicing is every 12 months/15,000km whichever occurs first. Capped-pricing applies to the first seven scheduled services up to seven years/105,000km totalling $3971, or a pay-as-you-go average of $567 annually. Alternatively, Kia offers pre-paid servicing packages with cost savings for three, five or seven-year terms.

There are currently more than 160 Kia dealerships across Australia, which also provide vehicle servicing.
