BMW M4 vs Jeep Renegade

What's the difference?

Brutal, bruising and utterly brilliant, the M4 CS will be an acquired taste due to its no-compromise approach, but those willing to take the leap will find a performance car like few others at their disposal.

Rugged, dependable and good off-road are the most obvious qualities of the Trailhawk. It stands out from the rest of the mini-SUVs by being able to do the S and the U with plenty of vigour.

It's just a shame that its on-road manners can't match that of its big brother, the Cherokee. Unless you're planning on proper off-roading, the Trailhawk might not be quite what you're looking for.

The M4 CS is familiar in all the right ways, but definitely looks significantly jacked up compared to its lesser siblings.

Part of that is the extensive use of carbon everywhere, from its bonnet panels to its roof, front lip, side skirting and boot spoiler. But also because of its super-muscular angles and creases, including the huge dome in its bonnet.

Also exclusive to this M4 CS is the light treatment, with the front LEDs lighting up with yellow highlights the brand says are supposed to be reminiscent of GT racing cars.

At the back, the rear lights are flush with fibre optic lighting, lending a flowing and unique light signature that looks epic at night.

Inside, it's a sea of carbon, with the lightweight racing seats, the dash inserts and the centre console all lined in it. It is a perfectly finished space, though, and one that's also flecked with red, including a 12 o'clock band on the thick-rimmed steering wheel, the seat backs, the contrast stitching and the paddle shifts.

Be warned, though, it takes some acrobatics to climb into or out of the CS. The seat bottoms have these super high edges that double as grab handles, but require some awkward contortions to navigate.

In short, it looks angry, this M4 CS, inside and out.

In what is absolutely not a coincidence, the Renegade immediately conjures up the Wrangler. Upright grille from the Willys Jeep (references abound here), round headlights, squared off wheel arches to mimic the Wrangler's guards, short overhangs and big rear view mirrors.

The 17-inch wheels look completely lost in the wheelarches which are even more cavernous owing to the Trailhawk's 50mm of extra ride height. The wheels are also a bit cheap looking but will probably survive the belting the car is intended to take.

Less rugged is the interior, despite a fairly self-conscious effort to make it look and feel chunky. The front seats are flat and unsupportive with the rears just as lacklustre making sure everyone is sliding around together. Luckily, front passengers get a dash-mounted grab handle.

It seems quite well put together, however, but with carpets and easily-marked plastics, you'll hope your passengers don't bring the mud in with them too often. And the "Since 1941" stamped into the steering wheel can go.

The dashboard is reasonably clear and has plenty of information to share via the screen between the dials but whoever thought marking the redline with a water splash graphic in bright orange should probably rethink their design decisions.

Storage is limited to two cupholders up front, door pockets in each door and nets on the front seat backs.

The Renegade range starts at $28,000 for the 1.6-litre Renegade Sport manual front-wheel drive, climbing between $2000 and $3000 through the Sport Auto, Longitude Auto, Limited Auto with a final jump of $4000 to the 2.4-litre auto-only Trailhawk.

Standard is a nine-speaker stereo with Bluetooth and USB, 17-inch alloys, dual-zone climate control, reversing camera, rear parking sensors, keyless entry and start, cruise control, electric front seats with heating, satellite navigation, automatic bi-xenon headlights, auto wipers, leather trim, roof rails, front and middle bash plates, full size spare, heated leather steering wheel, privacy glass, trailer sway control and tyre pressure monitoring. 

The lairy Omaha orange is $500, part of an eleven colour palette with only two no-cost paint options (black and white).

You can add lane departure warning, auto-parking and a black painted roof for $500 each, a removable and retractable roof called My Sky Roof for $2200 or a more conventional electric sunroof for $1900.

The Beats-branded nine-speaker stereo is run via Fiat-Chryser's UConnect system, accessible through the 6.5-inch touchscreen. While it improves with every attempt, it's still quite clunky and when the sat-nav is added, becomes a bit of a mess.

Thankfully, not every function has been crammed into the touchscreen interface, so you'll spend more time with your hands on the wheel rather than working out which bit of the screen has the climate control.

BMW has found yet more grunt lurking in its trusty 3.0-litre 'M TwinPower' six-cylinder petrol engine, with the M4 CS now pumping out 405kW and 650Nm.

That's a decent jump from the 390kW and 620Nm served up by the M4 Competition, and a giant leap from the outputs of the 'base' M4 – 353kW and 550Nm.

Predictably, then, the CS is the fastest of the lot, knocking off the run from 0-100km/h in 3.4 seconds, compared to 3.5 and 4.2 in the Competition and M4, respectively. The top speed is also dialled up to 302km/h.

All that power is channeled through an eight-speed automatic and sent to all four wheels on demand, with the help of an 'Active M Differential'.

The Trailhawk is powered by Fiat's 2.4-litre four naturally-aspirated four-cylinder producing 129 kW and 230 Nm. Jeep reckons you'll get 7.5L/100km on the combined cycle. Our mostly city driving with a longish motorway run produced an 11.0L/100km average over a week.

The transmission is a nine-speed ZF automatic driving all four wheels.

The Trailhawk also has Jeep's five mode Selec-Terrain system which should cover pretty much every eventuality – Auto, Sport, Mud, Sand and, just for the Trailhawk, Rock. The Trailhawk is rated to tow 400kg unbraked and 907kg braked.

The hardest and angriest M4 of all time is, perhaps unsurprisingly, hard and angry. This is a race track specialist, but because I don't happen to own one of those, my first experience with the barking (and barking mad) M4 CS was navigating my way back from BMW's inner-city dealership.

Like it or lump it, you're going to read some Porsche comparisons here, because you're talking not too far off base 911 Carrera money, and suddenly I find the two Germans doing battle for a spot in my dream garage.

First things first, the BMW won't be much chop for daily driving for most people. Happily, I have a sickness for uncomfortable sports cars. It tells me that no compromises have been made in the pursuit of punishing performance.

A good thing, too, because the BMW, at city speeds, can be punishing. Everything feels heavy, the seats aren't overly comfortable – especially the hard bits that tend to dig in when cornering – and it stiff-arms its way over road imperfections, that exhaust booming and barking as it does.

Again, I loved it, and you probably will, too. But it's still not the kind of car I'd relish sitting in the morning peak hour rush in.

But escape the confines of the city and the BMW M4 CS suddenly makes a whole heap of sense. The acceleration is genuinely brutal, and wonderfully theatrical, with that quad-tipped titanium exhaust barking and snarling as you rocket towards 100km/h.

The steering is brilliant, with feedback fed to your wrists via that thick-rimmed wheel, and the entire experience feels sharp, super engaging and edgy.

You can push the M4 hard and fast, and I'm certain my limited talents would run out far before the BMW's would, but there's this thrilling sense of peril sparked by the aggression of the experience, that I love.

It's like the magic of a roller-coaster, I guess. Even if you know nothing is going to happen, you never really know, right? And in that lies the magic.

But back to original question, this or a Porsche 911? There's no doubt a Carrera is a better all-rounder, in terms of comfy commuting and race track fun, but this angry M4 is all shouty theatrics, all of the time.

I bloody love it.

The Trailhawk name suggest that things are going to get muddy – compared to the rest of the range, the range-topper rides 50mm higher and has exposed, easy-to-reach tow hooks in the fairly unlikely event you get stuck. It also has a 20:1 low-range crawl ratio and Active Drive 4x4 which means it can switch between front and all-wheel drive. It'll also wade through almost half a metre of water. It's a genuine mud-plugging proposition and will take on some much bigger machinery out in the bush.

On the road, where we spent all our time in the Renegade, it's not what you'd call particularly inspiring. There's a number of sources of noise that contribute to a less than quiet cabin and having to constantly correct your course at freeway speeds adds to the tiring nature of the Renegade.

It's much better at lower speeds, pottering around but then again, its nine-speed transmission needs a lot more work on the shift mapping because it seems to forget which gear it needs to be in when you sink the right foot. If you don't need the Trailhawk's extra off-road goodies, consider the 1.4 litre Limited or Longitude.

Seven airbags (including driver's knee bag), traction and stability controls, roll mitigation, blind spot monitoring, ABS and brake assist.

The Renegade does not yet have an ANCAP star rating although it scored five EuroNCAP stars in 2014.
