Genesis G70 vs BMW M5

What's the difference?

The updated Genesis G70 3.3T Sport Luxury is beautiful to look at and drive. It features premium features, trims and great power but the cabin is tight on space. Which makes it a little awkward to use, so this will suit a small family best or families where this may not be the primary mover. That said, I love the after-care program and it suited my small family of three, so it gets an 8.0/10 from us. 

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.

The G70 sedan is absolutely gorgeous to look at and the our test vehicle's 'Kawah Blue' paintwork makes the crisp pleating across the body stand out.

The G70 has a muscular stance, much like its BMW rival, but the rear is softer in its shaping.

The front looks sophisticated with the wide-set LED lights and black air-intake vents. The sporty 19-inch alloy wheels and red calipers behind them hint at what the powerful V6 engine can do.

The interior looks high-end with our test vehicle’s white quilted Nappa leather upholstery and a soft-touch black headliner. The dashboard looks solid and robust but the slick looking 10.25-inch touchscreen multimedia system and digital climate control panel elevate the overall design. 

The only thing I didn’t like about the design was the ambient lighting. It’s limited to two panels on the roof and is a little distracting when you drive at night. I think if it was scattered more throughout the cabin, it would be less intrusive.

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 practicality is hurt a little by the space available for passengers. The front row benefits the most when it comes to head- and legroom but if you’re ferrying passengers in the back seat, you’ll have to scoot your seat forward to accommodate them.

Especially if they’re tall because my knees brush the back of the driver’s seat when it’s in my driving position and I’m only 168cm tall!

The individual storage options throughout the car are okay for the class with the front enjoying a small middle console and glove box, two cupholders and two small drink bottle holders in each door.

The rear gets map pockets, two cupholders in a fold down armrest and two very small storage bins in the doors.

The other amenities are great in both rows and a high-level of comfort will be found for adults with the heat and ventilation functions on the front seats and the heat function on the rear outboard seats.

However, the width of the rear seat and the tall transmission tunnel means the middle seat should be strictly reserved for a kid. Think of the G70 as more of a four-seater if you have adults to carry.

The boot has a 330-litre capacity and it’s not too hard to reach to the very back if items roll that way. The back seat has a 60/40 split and there is a temporary spare tyre underneath the floor. 

In terms of technology, you get a USB-A and USB-C port up front, as well as, a 12-volt socket and wireless charging pad to choose from. Rear passengers get two USB-C ports and the boot features another 12-volt outlet.

The 10.25-inch multimedia system looks great and is easy to use with a responsive touchscreen. It also has built-in satellite navigation, wired Apple CarPlay and Android Auto and the system now features over-the-air updates and Genesis Connected Services functionality.

The digital climate panel is responsive and very simple to operate, which is handy when on the go. The 12.3-inch digital instrument cluster is semi-customisable and it’s handy that the 8.0-inch coloured head-up display pulls through satellite navigation directions and traffic sign information. 

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.

The G70 3.3T Sport Luxury sedan has a 3.3-litre V6 turbo-petrol engine with a maximum power output of 274kW and 510Nm of torque. The G70 sedan is a rear-wheel drive and features an eight-speed auto transmission.  

The V6 engine responds eagerly, being able to do a 0-100km/h sprint time in just 4.7-seconds. Suffice it to say it’s fun to drive.

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.

The compromise for getting all of the power is that she’s a thirsty gal and the official combined cycle fuel consumption figure is 10.4L/100km and my real-world usage came to 10.6L/100km.

However, that’s after mostly doing open-roading – expect the fuel usage to be higher in an urban setting.

Based on the combined cycle and the 60L fuel tank, expect a driving range of around 577km on average. Which means you’ll be filling up more on a longer journey than more efficient sedans.

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 G70 sedan is a lovely car to drive with graceful handling and a good well of power to dip into.

That oomph is there when you need it and it’s as easy to drive in the city as it is on the open-road.

The responsive steering makes the G70 sedan feel nimble and well-balanced in turns, even when you accelerate out of a hair-pin corner.

The suspension is on the firm side and that can lead to a few grunts when you hit bigger bumps but the ride is not unpleasant, even for back-seaters. 

The cabin is generally quiet but you can get road/wind noise at higher speeds. It’s not enough to intrude on chatting but you don’t forget it’s there, either.

The G70 sedan is easy to park because it has an outstanding 11m turning circle. The 360-degree camera system is clear and the front and rear parking sensors make light work of a tight car park.

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 Genesis after-purchase program is hard to beat and such a treat because you get five years or up to 50,000km complimentary servicing with the G70. How good is that? 

The G70 also comes with a five-year/unlimited km warranty and the servicing intervals are every at 12-months or 10,000km, whichever occurs first. The interval could be annoying if you travel a lot but any annoyance will be softened by the fact that the services are free.

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.
