BMW M135i vs Ford Mustang

What's the difference?

To answer the question of whether it matters that the new 1 Series is no longer rear-wheel drive, I say no it doesn’t. It may not be as romantic on the absolute limit, but it is better in every measurable way, and still feels distinctly BMW despite moving to the conventional layout of its rivals. 

Be sure to check out Mal’s video review from the 1 Series launch last December:

Having driven the latest example of the Mustang GT, I hope Bill Ford is true to his word and keeps the V8-powered Mustang for as long as possible. It isn’t the most razor-sharp sports car or the most powerful muscle car, but it offers the kind of driving thrills and enjoyment that have made the car an icon.

The price increase is steep but the new technology inside drags the Mustang into the modern era and will add more youth appeal to a car that is largely unchanged in concept for the past 60 years.

But now that I’ve driven it in the USA and France, I can’t wait for it to finally reach Australia.

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

Yes, that kidney grille is rather large. If you want everyone to know you drive a BMW, you’ll love it. If not, get used to it. The X7, recent 7 Series update and upcoming 4 Series suggest they’re only going to get bigger. 

Nose aside, the 1 Series hatch has always had a distinctive, long-bonnet profile, which has generally been attributed to the rear-drive layout. Despite the move to a transverse engine, the new one is actually very close in proportions when compared side by side.

It’s just 5mm shorter in overall length and 13mm taller, with body width being the most notable change at 34mm wider. 

The key difference is that the front and rear wheels have been moved further back into the body, because of said engine layout change, and to make more back seat space in the rear.

Surprisingly for a model aimed at a younger demographic, the new 1 Series interior design isn’t quite the same step forward as the recent G20 3 Series.

It’s a cut above the X1 and X2 SUVS the new 1 Series shares its underpinnings with in terms of the shapes used, but is still classic understated BMW. 

However its headline act is the Live Cockpit driver display on both models, which gives you fully digital instrumentation and replaces traditional analogue gauges once and for all.

While this is considered a ‘new generation’ Mustang, the reality is this is more of a major overhaul than a complete, blank sheet redesign. As such, there’s a lot of carry over to the design, but that’s not to say there aren’t some significant changes.

For example, it’s still clearly a Mustang in its silhouette, sharing that with the sixth-generation model it replaces, as well as the now-iconic 1960s Fastback models, but the details are noticeably different.

To try and create more differentiation between the GT and EcoBoost models, Ford has designed unique front ends for each. Both are characterised by a strong horizontal line across the front of the more angular grille that meets the new ‘tri-bar’ daytime running lights.

The EcoBoost has an upper grille similar in size to the out-going model, the GT is a much larger upper section which incorporates a pair of ‘nostrils’ as well as a bonnet vent - both of which are functional for cooling and aerodynamics.

Down the sides Ford has lowered the beltline and created a more defined rear fender ‘shoulder’ that helps create the impression of a wider car. 

At the rear the famous ‘tri-bar’ lights remain and there are unique diffusers for each model, with the EcoBoost running two exhaust tips and the GT getting quad pipes.

But it’s inside where the biggest design changes have happened. The retro-inspired cabin of the sixth-generation - which features shiny silver plastic toggle-like switches and round air-con vents - has been overhauled.

The iconic ‘double brow’ design to the dashboard, which dates back to the original 1964 Mustang, has been dropped and replaced with a pair of digital screens. There’s a 12.3-inch display for the digital instrument cluster and a 13.2-inch multimedia touchscreen.

This change is designed to appeal to a younger audience but also allows for greater customisation and variety of displays, with Ford developing six different instrument panel options depending on the setting the driver chooses.

The primary three are the 'Normal', 'Sport' and 'Track' modes, which have been inspired by the GT supercar and the Mustang Mach-E electric SUV, while there’s also a 'Calm' setting, providing only the necessary data, such as speed, in a simplified format.

The final two have been created to tailor to fans of the brand’s 1980s ‘Fox Body’ Mustang, with digital versions of its round analogue dials in both a ‘Day’ and ‘Night’ mode, with the former using white graphics and the latter getting retro green dials.

With my modest 172 cm height, I never had any trouble with the old model, but the new 1 Series is a bit more more spacious by all the important measures.

The back seat base and backrest are a bit flat though, which is probably to help the backrest fold almost flat, but probably not very supportive during hard cornering.

There's also no centre armrest in the back or cup holders, but you do get bottle holders in the doors.

You also get two ISOFIX child seat mounts and there’s two USB-C charge points in the back of the centre console, but there's no directional air vents unless you opt for the dual-zone climate control that comes standard with the M135i. 

The boot has grown by 20-litres to a pretty impressive 380 litres VDA which includes a very useful cavity under the floor instead of a spare tyre. An inflation kit is there for those duties. With the back seat folded flat, boot space expands to 1200 litres VDA. 

The sixth-generation Mustang copped a lot of criticism for its interior look and feel, and while it certainly wasn’t at European levels of quality it was more affordable than any European V8-powered coupe.

The introduction of the new digital displays certainly adds a more premium impression to the cabin when you get inside, but you can still see a lot of the previous generation in this model, in particular the doors and centre console.

It’s pretty practical, for a sports car, with a pair of cupholders and a lidded centre console box for small item storage. 

One noticeable issue with the screens is the control virtually everything to do with the multimedia, including the air-conditioning, so trying to make small temperature adjustments is more complicated than just pressing a physical button. 

Not surprisingly space feels very similar to the outgoing Mustang with supportive and comfortable seating up front that made long stretches behind the wheel feel easy, which is nice for a sports car.

As for the rear seats, they remain incredibly tight for space and are better for soft item storage rather than squeezing people into.

Despite the largely carried over body and interior, the boot is slightly smaller than the previous model, with the coupe measuring 376 litres compared to the 408 litres offered previously. 

Ford Australia hasn’t confirmed the complete list of specifications for the seventh-generation Mustang range, but pricing has been locked in and we do know all three initial models - Dark Horse, GT and EcoBoost - will be offered here.

Having previously driven the Dark Horse in the USA in 2023, this time we sampled the GT and that’s the model we’ll focus on in this review.

We already know it will be priced from $77,002 for the six-speed manual and $80,902 for the 10-speed automatic coupe (both prices exclude on-road costs). The GT will be the only convertible option for Australians (and will only be available with the auto), priced from $86,102.

That’s a significant price rise from the out-going model, jumping up nearly $12,000 ($11,712 to be precise), which means it will be more expensive than the Nissan Z ($75,800) and closer to the BMW-based Toyota Supra (starting at $87,380).

On the plus side, this price increase is expected to come with a ramp up in standard equipment, including a new digital dashboard which features a pair of large screens, as well as the introduction of the line lock feature we missed on the previous model and the all-new 'Drift Brake'.

Both cars use versions of the three and four cylinder petrol engines from before, with the popularity of automatics leaving the previous manual option consigned to history.  The 118i’s 1.5-litre turbo three cylinder now produces 103kW/220Nm, with max torque available all the way from 1480-4200rpm. The 118i now uses the seven-speed dual clutch automatic transmission, as seen on Mini models that use the same engine. 

The M135i’s 2.0-litre turbo has been tweaked to take the place of the six-cylinder M140i from the last model and now produces 225kW/450Nm, with max torque available all the way from 1750-4500rpm. Its auto remains a torque converter though, but now the transverse-mounted unit also shared with Mini models with the same engine and splitting drive to all four wheels via the xDrive system for the first time. The drive split is constantly variable, but the rear bias tops out at 50 per cent and the only limited slip diff is an electric unit on the front axle.

During the top secret development of this seventh-generation model there were plenty of rumours that Ford was considering a hybrid system for this Mustang. Fortunately for lovers of old-school V8 engines that proved not to be the case.

Instead it’s powered by a 5.0-litre V8 that's an evolution of the ‘Coyote’ unit from the previous ‘Stang but now featuring some technical changes, including dual throttle-bodies and separate airboxes to help improve performance. In the GT it’s tuned to make 345kW and 550Nm.

It can be paired with either a six-speed manual gearbox or 10-speed automatic transmission, both sending all the power to the road via the rear wheels.

Official combined fuel consumption is a decent 5.9L/100km with the 118i, but the M135i steps up to 7.5L/100km) 2.0 litre four in the m135i. Both engines require premium unleaded. 

Fuel tank sizes vary across the two models also, with the 118i measuring 42 litres and the M135i managing 50 litres, despite its need to package rear drive components somewhere under there also. 

This results in a decent theoretical range between fills of 711km for the 118i and 666km for the M135i. 

While it hasn’t been confirmed by Ford, the Federal Government's Green Vehicle Guide has the Mustang GT rated at 12.8L/100km. And while that’s quite a thirst for unleaded petrol, it shouldn’t come as a surprise given it’s a 345kW 5.0-litre V8 engine.

If you value efficiency in your American muscle car, the four-cylinder turbocharged EcoBoost is rated at 9.4L/100km. But based on previous evidence, Mustang buyers are likely to opt for power over saving petrol.

The claimed consumption figure translates to a driving range between fills of around 650km.

For a brand with a marketing slogan of pure driving pleasure, this is the important part, particularly given the new 1 Series has lost its rear wheel drive USP. 

Why do some of us love rear wheel drive? It tends to be more fun when you're driving on the limit, and generally makes for nicer steering because you're only using the front wheels to turn corners.

So how does the new 1 Series drive? That depends on which version. 

The 118i is quite a nice package really. It rides a bit more gently than what I remember in the A-Class and generally feels more like a premium product. It also feels a step ahead of the 2 Series Active Tourer it shares its underpinnings with, which is a good thing.

The three-cylinder engine is quite smooth for a fundamentally unbalanced triple, and it makes enough power to get you out of trouble. 

Do you miss rear wheel drive? Not really, as you can only tell the difference when you're going real fast, which let's face it, is not somewhere 118i drivers are likely to go very often. 

The M135i is a vastly different beast, as you'd expect. Aside from being real quick, it's that much tighter everywhere, but still definitely on the more comfortable side than what we expect the future full house M version to be.

The continuously variable xDrive all-wheel drive system does a great job of putting its power down, but the rear bias maxes out at 50 per cent, which is probably spot on for chasing lap times, but means you miss out on the tailiness of the old one altogether. 

So it’s not as classically fun as the old M140i, but it’s easily faster, and that's what will probably matter most to most buyers. 

As promised earlier, here’s how the Mustang GT felt powering through the French countryside…

But first, it’s worth acknowledging that, in truth, it wasn't hard work getting through the traffic even in the manual Mustang. While the clutch is on the heavier side, it’s got a smooth action and the engine's torque and flexibility make darting in and out of gaps in the traffic a breeze.

However,  once out on the open roads the Mustang really could run free. The V8 engine sounded fantastic bellowing out across the fields and through the quaint little villages we passed through.

As you'd expect, the V8 provides plenty of grunt, it's an incredibly flexible engine pulling hard right across the rev range and makes us appreciate even more that this now remains the last of its kind since the demise of the V8-powered Chevrolet Camaro and Dodge Challenger.

Driving the Mustang in conditions like this makes you understand why it has been such a popular sports car not only in Australia but around the world for decades.

While the manual transmission has fallen out of favour with Aussie buyers, the truth is it's the pick for this GT. The fact it has less ratios to choose from than the 10-speed automatic means it feels more urgent and (again) the flexibility of the engine allows it to shine.

Not that the auto is bad, it does a fine job, it just lacks the buzz and engagement the manual ‘box provides.

What arguably impresses even more than the engine is the handling. Having driven the Dark Horse last year and being so impressed by its handling, particularly with the 'Performance Package', there was some concern prior to driving the GT that it would feel less impressive and, dare I say, duller.

But that's far from the case. Instead, the GT feels responsive and well sorted across a variety of road conditions. While it may lack the precise handling characteristics of a European sports car, it’s clear Ford has made this latest Mustang better suited for the rest of the world, not just America.

Not that Ford has made the Mustang too serious, as the introduction of the Drift Brake demonstrates. This rally-style electronic handbrake allows you to, as the name suggests, snap the car into a slide - when the circumstances allow.

Ford finally gave us our first (official) use of the Drift Brake when it paid us up with stunt driving expert, Paul Swift, who taught us how to slide the Mustang into a parallel park.

Obviously this is not designed for road use but for those who want to take their Mustang to the track it will no doubt lead to a lot of fun and some shredded tyres.

Full safety specifications haven’t been announced, but in the US, where it’s already on sale, all models are equipped with at least a reversing camera, rear parking sensors, auto high-beam headlights as well as front, side and driver’s knee airbags.

There’s also a decent level of active safety gear with pre-collision assist with autonomous emergency braking and lane departure warning all standard. But adaptive cruise control, lane centring assist and intelligent speed assist are all optional.

Frankly, after my French experience I’d be hoping the lane centring assist is an optional locally because the overly sensitive system drove us crazy on our French test drive.

Repeated warnings to ‘put our hands on the wheel’ when our hands were firmly affixed to the tiller moved from just frustrating to borderline dangerous as the only way to trigger the system to stop making its request was to quite violently tug on the wheel and jerk the car in the lane. 

It’s another case of poorly calibrated safety systems that make you question the value of the technology in the first place, especially when you find yourself turning it off because it’s safer to just pay attention as a responsible driver.

It will be interesting to see if ANCAP crash tests this new generation Mustang, especially considering how closely related it is to the previous model.

ANCAP famously (or infamously, depending on your point-of-view) crash-tested the previous Mustang and awarded it two from a possible five-star rating.

Despite the public criticism it didn’t seem to impact Ford’s sales of the pony car, which remained a best-seller. 

Since the Mustang, ANCAP has not tested any of its rivals, with sports cars including the Toyota Supra, Nissan Z and Subaru BRZ all unrated by the safety authority.

BMW is yet to step up to the five year warranty offered by most mainstream brands and now Mercedes-Benz and Genesis, continuing with the three year/unlimited coverage matched by Audi. 

As always, BMW describes the service intervals as condition based, and the car will alert the driver when a service is due. This will occur at least every 12 months though, but individual intervals will vary based on how the car is driven. 

This can all be bundled into five year/80,000km service packs though, with the Basic pack costing $1465, but the Plus pack adds brake pad and disc replacement to regular fluids and consumables for $3790. Assuming 12 month intervals, these prices are about average for a premium branded product. 

There are no details confirmed at this stage but there’s no reason to believe the Mustang won’t be covered by Ford Australia’s usual five-year/unlimited kilometre warranty.

Similarly, service intervals are likely to be 12 months/15,000km.

For reference, capped price servicing on the out-going Mustang GT came in at $299 for each of the first four services, up to four years/60,000km. Not bad.
