BMW M5 vs Honda Accord

What's the difference?

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.

Will the new Honda Accord e:HEV RS topple the SUV throne? Unlikely, but it proves sedans can still haul the family around in relative comfort and style.

The new Accord drives stupidly well and offers great ongoing ownership costs, even if it's price tag is a little steep. It's hybrid powertrain also offers fantastic efficiency and that's a big win.

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.

The design for the new Accord is powerful with a sexy silhouette that features a rear spoiler, black accents and sporty 18-inch alloy wheels.

The old chunky grille is long gone and at certain angles you almost get a Nissan 200 SX vibe, which is gorgeously retro and a refreshing take for Honda - which has been playing it safe for the last few years.

The interior is simply styled but looks timeless. The dashboard has clean lines and a featured honeycomb mesh that hides the air-vents. It's a feature which might not land with everyone but it adds personality.

The black upholstery looks plush and there are enough soft-touchpoints to make the cabin feel like it deserves a premium tag.

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.

Access to the cabin is great thanks to wide door apertures but the Accord is a low car to get in and out of with its 134mm ground clearance. Expect a couple of grunts when parked on a hill!

Both rows offer ample legroom but the front enjoys the best of the headroom. A 183cm (6.0ft) friend was lumped with the middle seat and spent the trip dreadfully hunched over and uncomfortable. Save the middle seat for kidlets.

The electric front seats offer decent comfort for a longer trip but it's disappointing that only the driver’s side gets lumbar support.  

The rear row enjoys well-padded seats and amenities, like retractable sunblinds, reading lights, two USB-C ports and directional air vents but it took a while for the back to cool down on hot days which my kid made known. Loudly. 

Storage consists of a large glove box and middle console (which can accommodate a small handbag), a sunglasses holder, four cupholders, four drink bottle holders and two map pockets. There is also a dedicated phone tray but a few extra cubbies up front would be welcomed.

The boot offers plenty of space with its 570-litre capacity, which is great for the class, and you can also open up storage options with the ski-port door, if need be. The powered boot release is a handy feature.

The touchscreen multimedia system looks nice but is a pain in the butt to use until you set some time aside to get to know it. It’s just not intuitive but the screen is responsive and it's a bonus that you get the built-in sat nav and Google apps. 

The new Accord gets wired and wireless Apple CarPlay and Android Auto but it took a few beats to get the wireless CarPlay to work.

The charging options are good throughout the car with four USB-C ports, two 12-volt sockets and a wireless charging pad to choose from.

The model line-up has been streamlined for the new Accord and there’s only one variant available, the e:HEV RS model.

The new Accord is well-specified but misses out on some luxurious extras most of its rivals sport, like heated and cooled front seats, a heated steering wheel and heated rear outboard seats.

Which might all seem superfluous at first but maybe not when you consider the new Accord's $64,900, before on-road costs, price tag sits just shy of the more expensive Skoda Superb top model, which is $65,590, before on-roads.

The next two rivals are more affordable with the Mazda 6 Atenza priced at $52,590 MSRP and the new Toyota Camry SL at $53,990 MSRP.

The standard equipment list for the new Accord includes leather-appointed upholstery, electric front seats, lumbar support for the driver's side and a panoramic sunroof.

There's also keyless entry and start, adaptive LED headlights, a powered tailgate and a host of high-end technology throughout.

That includes a new 12.3-inch touchscreen multimedia system with satellite navigation and built-in Google apps, wired/wireless Apple CarPlay and Android Auto, the Honda app (with over-the-air updates), a 10.2-inch digital instrument cluster, dual-zone climate control, a wireless charging pad and a 12-speaker Bose sound system.

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.

Our test vehicle has an electric continuously variable transmission and features a new self-charging hybrid powertrain that couples two electric motors with a 2.0L, four-cylinder petrol engine that combine to produce 135kW of power and 335Nm of torque.

Only being available in one powertrain may limit its audience but the combo delivers decent performance for a sedan of this size.

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 new hybrid powertrain means lower outputs and the official combined fuel cycle figure is just 4.3L/100km! Which is only beaten by the Toyota Camry's 4.0L/100km.

The on-test figure pops out at 5.1L/100km after doing a some urban stuff but mostly open-road driving. Which is where hybrids tend to be the least efficient, so the fuel usage is excellent.

Based on the official combined (urban/extra-urban) fuel cycle and 48L fuel tank, you should see a theoretical driving range of up to 1116km, which is a little less than the Toyota Camry but still an amazing range for a family car.

That range figure drops to around 940km using our real-world average consumption number.

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.

Power delivery for the new Accord is pretty punchy and, in most scenarios it’s responsiveness is great. But occasionally, when you’re getting up to speed, there can be a small lag before things kick in.

The Accord handles like a dream and feels firmly planted on the road in corners. Even in high winds, the car feels stable and sure of itself. Delightful.

The cabin is quiet and engine noise is at a minimum most of the time. Around town, the Accord sounds and behaves like an EV. Only once you hit the open road do you get some road noise but it never intrudes on chatting.

It might also be one of the easiest sedans to park and it's got a lot to do with the top-notch 360-degree view camera system and direct steering.

The new Honda Accord hasn’t been assessed by ANCAP yet, but it has eight airbags, which includes a knee airbag for the front passenger, but you miss out on a front centre airbag.

Standard active (crash avoidance) safety tech includes blind-spot monitoring, driver attention alert, rear occupant alert, forward collision warning, tyre pressure monitoring, rear cross-traffic alert, lane departure alert, lane keeping aid, traffic sign recognition, intelligent seatbelt warning, a head-up display, adaptive cruise control and a 360-degree camera system as well as front and rear parking sensors.

There are two ISOFIX child seat mounts and three top tethers. The rear seat is wide enough to easily accommodate two big booster seats but you might get lucky with three smaller seats.

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. 

The Accord comes with a five-year/unlimited km warranty, and an eight-year battery warranty, which are now normal terms for the class.

You get a five-year capped priced servicing program and it costs just $199 per service, which is very competitive.

Servicing intervals could get annoying if you put a lot of kays on your car as they're set at every 12-months or 10,000km, whichever occurs first.
