MG MGS5 EV vs BMW 528i

What's the difference?

Benchmark is a big word. But I’ve been testing cars long enough to know when and where to use it, and if my motoring instincts are correct the MG S5 EV could be the new benchmark for budget small electric SUVs.

Still we’ve only driven one grade - the Essence with the bigger 62kWh battery. We need to get the other grades into the garage to test them too, but on first impressions the MG S5 is outstanding for price, practicality, styling, ownership, and the way it drives.

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.

The MG S5 EV is a completely new car. Unlike the ZS EV which was a combustion car that was later turned into an EV, the S5 EV was designed from the start and built as an electric vehicle and that’s super important for everything from space to how it drives.

The S5 EV is a bigger car than the ZS EV. It’s 153mm longer and 40mm wider and it shares the same underpinnings as the excellent MG4 hatch.

The S5 EV looks a bit like the MG4 but an SUV version and I think the styling is a massive improvement over the ZS EV. This thing looks snatched with its sleeker shape and a smooth modern face, the blade-like LED running lights sitting atop the headlights and I really like the treatment to the tail-lights as well and the way the boot lid flicks up into a little integrated spoiler.

It's a far more refined, mature and prestigious look to the ZS EV. And while we're being completely subjective here I also think it's better looking and more refined than the BYD Atto 3 and Chery E5.

That same refinement and modernity is everywhere in the superb cabin from the clean dash design and door trims, to the steering wheel and floating centre console.

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 MG S5 EV’s practicality is also outstanding and while it’s early days, it could be the new benchmark for the class. It's a spacious cabin with superb ergonomics and excellent storage.

Even as a taller person (I’m 189cm) there was plenty of elbow, shoulder and legroom for me as a driver and also to sit behind my driving position in the second row.

Storage is excellent with giant bottle holders in all the doors, stowage under the floating centre console, four cupholders and a flat space for your phone which also is a wireless charger on the Essence.

It’s such an ergonomic and practical cabin even the buttons are practical. There’s a volume dial, and physical buttons and switches for the climate control switch, not screen buttons.

And then there’s the boot, at 453 litres it’s about 10 litres bigger than the ZS EV’s cargo capacity. It's also 10L larger than the Atto 3 and a lot bigger than the Chery E5’s boot.

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.

BMW's venerable 5 Series is now 45 years old, and this all-new model arrives in four distinct flavours, with a fifth - an incoming M5 performance sedan - still some way off.

For now, though, the range kicks off with the 520d, before stepping up what BMW hopes to be the big seller of the range, the 530i (replacing the outgoing 528i). Next up is biggest diesel, the 530d (replacing the the 535d), before the current range tops out with the petrol-powered 540i (replacing the old 535i).

Be warned though, there's been some pretty serious price increases right across the line up, ranging from $9,145 to a whopping $19,245. In fact, only the 530d has seen its price come down, now $3,755 cheaper than the outgoing 535d. BMW justifies the hikes by pointing to an increase in standard inclusions across the range.

It might not be the most head-turning offering, but the 5 Series sedan remains sleek, powerful and understated.

The 520d kicks off from $93,900, and arrives predictably well equipped for your money. Expect 18-inch alloys, leather trim, dual-zone climate control and a 12-speaker stereo. You'll also get a technology overhaul, with a bigger and upgraded Head Up display (it can now read street signs and beam that info onto the screen), a 10.25-inch touchscreen and a wireless (insert link to chi charger story) charging pad.

Step up to the 530i ($108,900) or 530d ($119,900) and you'll add 19-inch alloys, adaptive dampers with dynamic mode (that reads both driver input and navigation data and tweak suspension, gear and steering settings automatically) a 16-speaker Harman Kardon stereo and a crystal-clear 12.3 high-resolution digital display in the driver's binnacle. You'll also find heated front seats, a powered boot and sports seats in the front.

Finally, spring for the 540i ($136,900) and you'll get 20-inch alloys, a sunroof and electric blinds for the rear windows. You'll also find better Nappa leather on the seats, which now also offer a cooling function. Under the skin, you'll get an active anti-roll bar at each axle designed to keep the car from rolling side-to-side on the twisty stuff.

One quirk, however, is the fact that BMW's very cool wireless Apple CarPlay is a cost option on every trim level, and one that will set you back $479.

The MG S5 EV has one electric motor driving the rear wheels and it has an output of 125kW and 250Nm. That’s plenty of grunt to move this electric car quickly and instantly in a way that feels controllable and smooth. 

While front-wheel-drive cars are absolutely fine, rear-wheel drive tends to offer more engagement and feel, and that's an added bonus for the S5 EV.

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.

The MG S5 EV’s energy consumption varies depending on the grade and battery size.

The most efficient in the range is the entry grade Excite with the 49kWh battery with MG saying on a combination of open and urban roads it should use 16.6kWh/100km (WLPT). The biggest energy user in the range is the Essence grade with the 62kWh battery with 17.1kWh/100km.

As for the range, this varies from 335km in the 49kWh Essence to 430km in the 62kWh Excite.

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.

The MG S5 EV is outstanding to drive for an electric vehicle at this affordable price point. Again, I’m going to put it out there and suggest it could be the new benchmark for the more affordable end of the small electric SUV segment. Kia's EV3 is also a winner on the road, but it's quite a bit pricier than the MG.

I was never a fan of the way the ZS EV drove, from its seating position to ride and handling. But the MG S5 EV is completely different to pilot. It’s excellent.

This car feels so composed on the road, the body control is excellent, the steering is well weighted and direct, the visibility is excellent and the pedal feel under my feet is solid, too. And all of that is combined with an electric motor that makes the perfect amount of power.

Add to all this the rear-wheel-drive component and the MG S5 EV is not just easy to drive but engaging as well.

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.

Expect plenty of clever safety gear, with every 5 Series sedan arriving with six airbags (dual front and full-length side airbags, along with head protection bags for front passengers). You'll also find a surround-view reversing camera and parking sensors.

But the high-tech stuff arrives courtesy of active cruise control, cross-traffic alert, lane keep assist and cross-road alerts.

The MG S5 EV is covered by MG’s 10-year 250,000 kilometre warranty. And that includes the battery. Regular families though do about 10,000km a year or 20,000km maximum, so this warranty offers excellent coverage for them.

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.
