Toyota HiAce vs BMW M5

What's the difference?

The HiAce maintains its staggering 50 per cent share of the mid-size commercial van market for numerous compelling reasons including its versatility, as evidenced by the diverse range of Aussie businesses that rely on it. Toyota’s latest suite of safety and other upgrades makes it even better.

Let’s get one thing out of the way: the new M5 is a very good car. Considering the emissions limitations and size increase of its base model, it is an impressive bit of engineering. 

What’s trickier is deciding whether the new car is really better to drive. Less edgy but supremely comfortable and quiet; BMW leaned into the daily usability of the plug-in hybrid M5 rather than amping the petrol-electric system for maximum thrills. And do you know what? That’s fine with me. 

The new M5 still performs on road and track and does an incredible job of hiding its weight (most of the time). Perhaps the G90 is a little more Audi RS6 than F90 in its demeanour but some would argue that’s no bad thing. 

The concept of the BMW M5 is not static, it evolves with the times, and the G90 is no exception. Expect future Competition and CS variants to unlock some extra lunacy. 

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

Apart from the recent safety upgrades, our LWB test vehicle resolutely adheres to a design that’s been perfected through decades of hard yakka.

Its simple and robust unitary chassis features MacPherson strut front suspension, a leaf-spring live rear axle, rack and pinion steering and (on all automatic variants) four-wheel disc brakes.

The HiAce’s traditional rear-wheel drive layout has an inherent traction advantage over front-wheel drive rivals, particularly when towing and hauling heavy loads on low-grip surfaces.

It also ensures the front wheels can be turned sharply enough for its 3210mm wheelbase to deliver an impressively tight 11.0-metre turning circle. And its 1990mm height also allows access to underground loading docks and multi-storey car parks.

There’s no load-floor liner or cabin bulkhead included as standard equipment, but both are available as Toyota genuine accessories. The use of unpainted plastic bumpers is designed to best withstand the wear and tear often evident in these areas on hard-working vans.

The cabin is spacious and airy, with a neat and functional dash design featuring large and clear instrumentation and (thankfully) physical dials and buttons rather than distracting touchscreens for the main controls that are easy to reach and operate. It’s a commercial van that’s easy to live with.

The M5’s raw size is what you notice first. The G90 M5 is a whopping 113mm longer, 67mm wider and 37mm taller than the car it replaces, with the wheelbase stretched 24mm.

It is also the most pumped M5 yet, compared to a 520i it is 70mm chubbier at its flared wheel arches. The ‘M5’ insignia on the C-pillar means you’ll know this is the fast one. 

Presence is not in question, then, but beauty? Not the right word. The G90 makes its predecessors — especially the original ‘E28’ — look demure. 

The cabin layout builds on the concept debuted by the iX electric SUV, with twin integrated screens and focus on technology and minimal buttons. Materials are mostly high quality and feel fitting for the M5’s asking price.

With its hefty 2260kg kerb weight and 3300kg GVM, our test vehicle has a 1040kg payload rating. So, it’s a genuine one-tonner and up to 120kg of that can be carried on Toyota’s triple roof-rack set.

The HiAce is also rated to tow up to 1500kg of braked trailer and with its 4800kg GCM rating (or how much weight it can legally carry and tow at the same time) it can carry its maximum payload while towing its maximum trailer weight. So, that’s more than 2.5 tonnes of combined cargo-carrying capacity, which would comfortably meet or exceed most job requirements.

Its cavernous cargo bay, which offers 6.2 cubic metres of load volume, is accessed from either side through sliding doors with 1010mm-wide openings, or through rear barn-doors with 180-degrees opening to allow easy forklift access.

The cargo bay is 2530mm long, 1760mm wide and 1340mm high, with 1268mm between the rear wheel housings allowing up to two standard Aussie pallets or three Euro pallets to be carried, secured by a choice of six load-anchorage points.

An unusual feature is the roof’s full-length internal lining, which we suspect contributes to at least some suppression of tyre noise emanating from the rear-wheel housings. The walls and doors are neatly lined to mid-height and there’s ample internal lighting.

Generous cabin storage includes a bottle-holder and bin in each front door, small bottle/cupholders in the centre and either side of the dash, plus a single glove box. The console between the seats offers another two bottle-holders plus generous internal storage, which is topped by a large hinged lid that can also serve as a storage tray or work desk.

BMW has persevered with its twin-screen, minimal-button approach for its 'Operating System 8.5' in the M5. 

The 14.9-inch central touchscreen is bright, responsive and high resolution but the software remains a little strange. The main interface is classy but when looking for settings to adjust you’re presented with a Windows 95-esque panel of small square touch targets. It’s not intuitive. 

Wirelessly mirroring Apple CarPlay or Android Auto works a treat, at least. Digital climate controls keep temp adjustment persistently on screen and a shortcut to fan speed. The nipple-like vent direction adjustment grows on you, as do the digital vent sliders. 

The 12.3-inch digital driver’s display still doesn’t have the freedom of customisation and clarity of Audi’s interface. 

The M5 has two cupholders, a deep central storage cubby, door bins that swallow two 600mL plastic bottles and twin wireless charging pad that resolutely grips smartphones even under the sort of tummy-churning G-Forces this M5 can manage. 

Setting the M5 apart from the regular sedan is a unique centre console bunching 'M Drive' modes, 'M Hybrid' modes and other shortcut functions together next to the gear toggle and M-engraved crystal 'iDrive' controller.

Comfortable front seats are power adjustable with in/out, up/down lumbar support and have two memory positions. 

The 5096mm long M5’s back seat is very spacious. Headroom is good for those beyond 182cm (six-foot), the bench is extremely supportive, while leg and toe room are adequate.

A fold-down centre armrest has two cupholders and there are USB-C charge ports in the back of each bucket seat for a total of four. 

You can buy an accessory mount that holds tablets or smartphones for rear seat passenger entertainment, too.

When you look in the boot, BMW offering a Touring version of the latest M5 makes even more sense. The load aperture is big but the usable space is narrow; the sides intrude on load space. 

The 466-litre space will make fitting suitcases for an airport run tricky and, even with the 40/60 split-fold rear bench, you will struggle to fit a bike in the back. There’s no spare tyre, either.

The last M5 was well equipped but the new car is wanting for nothing. Australian cars have just about every option for $259,900, before on-road costs.

Australian M5s wear staggered 20-inch front and 21-inch rear alloy wheels paired with standard metallic paint, 'M Carbon Exterior' package (including carbon roof and rear lip spoiler), adaptive LED headlights and BMW’s 'Iconic Glow' illuminated kidney grille surrounds. 

Keyless entry, a heated steering wheel, heated and ventilated front seats, interior camera, powerful 18-speaker Bowers & Wilkins sound system, M seatbelts, four-zone climate control and a power tailgate are the cabin highlights. 

Optional extras are thin on the ground; you can choose from (eight) no-cost paint colours and all manner of 'Individual' shades (from $4100), four interior trims including classy 'Dark Oak' wood and four leather colours. There’s classic black ‘Merino’ leather, or you can have it dyed with a mix of 'Silverstone', red or 'Kyalami Orange'. 

Aside from that, the only major option is carbon ceramic brakes at a staggering $18,500, and an M5 Touring wagon costs $263,900. 

Though the M5 is more expensive than Audi’s closest rival, the RS6, the gulf isn’t huge considering you get a lot more punch in the BMW. Mercedes-AMG does not have an E-Class answer, yet.

Good value, then? Well, an equally potent Porsche Panamera is twice the price. So yes, in a sense.

Toyota’s well-proven (1GD-FTV) 2.8-litre, four-cylinder, turbo-diesel produces 130kW of power at 3400rpm and, in auto models like ours, 450Nm of torque between 1600-2400rpm. Its Euro 5 emissions compliance doesn’t require AdBlue, which minimises maintenance and running costs.

The refined six-speed torque converter automatic offers the choice of sequential manual-shifting. Fuel efficiency is optimised with full torque converter lock-up on fourth, fifth and sixth gears, along with overdrive on fifth and sixth to minimise engine rpm when highway driving. The traction advantage of rear-wheel drive is enhanced by an electronically controlled automatic limited-slip diff.

Unlike the Mercedes-AMG C63, BMW has kept the M5’s eight-cylinder heart and this has proven to be a good decision. 

The 4.4-litre twin-turbo petrol engine has been optimised with “a cross-bank exhaust manifold and optimised oil separation”, says BMW.

The V8 spins to 7200rpm though it isn't a screamer, outputting a full-bodied 430kW (5600-6500rpm) and 750Nm (1800-5400rpm).

Augmented with a transmission-mounted 145kW electric motor that can produce up to 450Nm, thanks to pre-gearing, maximum combined outputs are 535kW and 1000Nm. 

Weight blunts punch, though, so despite nearly 100kW and 250Nm more, the new M5 is a tenth slower to 100km/h than its predecessor (claimed), at 3.5 seconds for the sprint.

You can thank a 220kW/tonne power-to-weight ratio, worse than the old car's 233kW/tonne figure. The new G90 claws some time back with brute force, hitting 200km/h in just 10.9 seconds and goes on to a limited top speed of 305km/h.

You can choose from five powertrain settings, starting with 'Electric' and 'Hybrid' for everyday use, while 'eControl' lets you store battery power for urban use.

'Dynamic' provides the best balance, says BMW, while 'Dynamic Plus' is like a qualifying mode. Think maximum combined punch for up to 10 minutes, at which point you’ll have drained the battery. 

Driving in pure electric mode, the take-off can be a little jerky but the quietude and decent power make it pleasant. Power sources are combined expertly in Hybrid and giving it some stick in Dynamic is more than enough to make your passengers feel queasy.

Toyota claims combined cycle (urban/extra-urban) average consumption of 7.8L/100km. Our 328km of testing was conducted with the engine’s auto start/stop function switched off and comprised the usual mix of city, suburban and highway driving, of which about one third was hauling a near-maximum payload.

Our own figure, calculated from fuel bowser and tripmeter readings, was 10.7L/100km. That’s still within the usual 2.0-3.0L/100km discrepancy between official and real-world figures and not bad for a vehicle weighing more than 2.2 tonnes driven mostly in metro settings and hauling more than one tonne during our test. So, based on our real-world consumption, you could expect a driving range of around 650km from its 70-litre tank.

Electric-only range is rated up to 69km in WLTP testing, but the 18.6kWh battery is more likely to give you around 60km in real-world driving. It can be topped up in about two hours using an 11kW AC charger, or overnight on a three-pin socket. 

BMW includes both Mode 3 (public) and Mode 2 (home) charging cables with the M5. 

The M5 uses 3.2L/100km of 98 RON premium unleaded in ADR testing, corresponding to just 72g/km of CO2, so it should sail through the first rounds of Australian emissions regulations. 

Indulging in what the V8 has to offer sees that consumption spike, though. An enthusiastic road drive saw the M5 gulp 12.4L/100km, according to the trip computer.

The driving position is comfortable thanks to a well-sorted combination of supportive seating with power-adjustable lumbar support, a leather-rimmed steering wheel that’s adjustable for height and reach and a large left footrest for extra support.

The standard kerbside sliding door includes a large window, which partly reduces the huge blind spot over the driver’s left shoulder created by the cargo bay’s solid walls.

Fortunately, the HiAce also comes standard with blind-spot monitoring to ensure safe lane-changing on multi-lane roads, while its rear cross-traffic alert and rear-view camera are equally valuable when reversing out of driveways into busy traffic.

The new electric power steering has more noticeable changes in turning weight compared to the more linear hydraulic system it replaces. Its variable-ratio assistance feels even lighter at parking speeds for easier manoeuvrability and becomes increasingly firm and direct as road speeds increase.

Ride quality is reasonably supple when unladen or lightly loaded and the 2.8-litre turbo-diesel, with its sizeable 450Nm of torque, has strong low-rpm response and displays good flexibility in city and suburban driving.

Internal noise levels below 80km/h are acceptable, but like all vans can become intolerable at highway speeds due largely to tyre roar emanating from the rear-wheel housings. So, if you do lots of highway travel, we’d recommend fitting Toyota’s genuine accessory solid bulkhead to insulate the cabin from this noise.

The six-speed auto’s shift calibrations feel like they’re getting the best out of this engine, particularly fuel-efficient highway travel which requires less than 2000rpm to maintain 110km/h. The sequential manual-shifting function can be handy in certain situations, though, like hauling/towing heavy loads in hilly terrain.

To test its GVM rating we forklifted 830kg into the cargo bay, which combined with our crew of two equalled a total payload of 1010kg that was only about 30kg less than its 1040kg limit.

The stout rear leaf-springs only compressed about 30mm, which left more than 60mm of static bump-stop clearance that was more than enough to ensure there was no bottoming-out on our test route.

Its ample torque made light work of hauling this payload in city, suburban and highway driving as well as our 13 per cent gradient, 2.0km-long set climb at 60km/h, which it easily cleared in third gear.

Engine braking on the way down, in a manually-selected second gear, wasn’t as robust but within expectations given the one-tonne-plus payload it was trying to restrain.

We also tested what we safely could of the HiAce’s latest safety upgrades in road use, which all worked as intended. The ‘lane trace assist’ function when using adaptive cruise control was outstanding, as it resolutely kept the vehicle centred in its lane even around curved stretches of multi-lane highway, without the driver needing to intervene.

The three M5 elements start with daily usability. We trundled out of Bathurst in electric mode, with the adaptive dampers (and other myriad settings) in Comfort. 

The M5 has steel springs, double wishbone front suspension and a five-link rear axle, all of which has been heavily reworked by the boffins at M. Naturally, the ride is firm, though in Comfort the body moves through its motions smoothly. 

The M5 is an effortless tourer, its eight-speed automatic shmoozing through ratios as it climbs and descends steep gradients. Wind and tyre noise insulation is good on coarse chip tarmac, though a bit more burble from the V8 would be appreciated. 

The M5 has nine adjustable parameters to wake it up: 'Drivetrain', 'Energy Recovery', 'Drivelogic' (gear shift aggression), 'Chassis', 'Steering', 'Brake', 'M xDrive', stability control settings and 'M Sound'. Favourite settings can be stored to the wheel-mounted M1 and M2 buttons. 

With the dampers still in Comfort the M5 remains fantastically capable with power delivery from the xDrive mighty rewarding on corner exit. Sport dampers sharpen the experience up further, amplifying the M5’s surprising agility. Thank the rear-wheel steer for this big sedan’s switchback performance. 

Step beyond the limit of grip, brake too late, or get on the power too early, though, and the M5’s mass reveals itself rapidly. It doesn’t help that the accurate steering is devoid of feel. The brake-by-wire pedal is too numb and light, as well, making it tricky to judge grip levels on the road.

Feel is less of an issue on a dry Mount Panorama circuit, where the M5 turns out to be a total pussycat. The all-wheel drive, consistent dynamics, strong brakes and well-tuned stability control make for an approachable but seriously fast sedan.

The responsive transmission will hold gears to redline and is eager on the downshift in its most aggressive setting while tactile shift paddles make commanding ratio changes yourself that bit more engaging. 

Prodigious punch out of corners is matched by the impressive consistency of the carbon ceramic brakes. The M5 pulled up for The Chase every time with minimal fuss, even from above 250km/h.

Similar credit goes to the 285mm front and 295mm rear Hankook S1 Evo tyres which remained consistent and predictable all day despite reaching temperatures over 130 degrees, according to the tyre pressure monitor.

The regular BMW 5 Series range scored a maximum five stars in 2023 ANCAP safety testing but this does not apply to the M5.

The M5 features nine airbags and a host of active safety systems, including auto emergency braking (AEB), blind-spot monitoring, rear cross-traffic alert, lane-keep assist, auto parking and speed limit assist. 

Lane-keep can easily be turned off via two taps but the other systems require more menu navigation, though are mostly unintrusive. A 'Track' mode disables lane-keep, AEB and other systems along with switching the central display off. 

The HiAce is covered by Toyota's five-year/unlimited km warranty which is in line with competitors like the Ford Transit Custom and Hyundai Staria Load but lags behind the LDV Deliver 7's seven-year term.

Scheduled servicing is a relatively short six months/10,000km interval, whichever occurs first. Capped price for the first 10 scheduled services up to five years/100,000km totals $3650, which is $365 per service or $730 annually.

Toyota currently has 275 dealers across its vast Australian network located in metro, rural and regional areas. Toyota dealerships are also service centres.

In Australia, BMW has moved to match other manufacturers in offering a five-year/unlimited kilometre warranty on all its cars. 

Servicing is recommended on a condition basis, with the M5’s multimedia system prompting a visit to the mechanics. BMW offers pre-paid service packs for five years/80,000km at a price of $5059 for the basic offer and $8152 for 'Inclusive Plus', which covers brake pad and rotor replacements. 

It is expensive next to a regular 5 Series but when you consider the purchase price and performance level, the M5’s service pricing is not astronomical.
