Beneath the bonnet everything's petrol-powered in the Renegade line-up these days.

Things kick off with the three front driven conventional models.

With these, you choose between an efficient 120hp 1.0-litre three cylinder petrol unit.

Or a four cylinder 1.3-litre powerplant, available in 150 and 180bhp guises.

Ideally, you want to try and stretch to the 1.3 because the base 1.0-litre unit doesn't really have enough pulling power to shove the Renegade along with much conviction.

The automatic gearbox that goes with the lower-powered version of the 1.3-litre engine isn't especially slick-changing; the uprated 9-speed auto 'box that goes with the 180bhp 1.3 is better.

Your dealer though, will also want you to consider one of the electrified models.

The first option is is the mild hybrid front-driven 'e-Hybrid' variant, which is based around a four cylinder 1.5-litre unit which puts out 130hp and 240Nm of torque and is mated to a 7-speed dual-clutch auto transmission.

The propulsion system includes a built-in 48 volt 15kW (20hp) electric motor delivering 55Nm of torque, which can propel the wheels even when the internal combustion engine is turned off.

Your final Renegade option is the '4xe' Plug in Hybrid variant, which is a 4WD PHEV.

To create the plug-in drivetrain, Jeep has taken the conventional version's 1.3-litre four-cylinder petrol engine (which for 'Longitude' and 'Limited' models has 128bhp) and mated it to an 11.4kWh battery pack and a 59bhp electric motor.

Total system output is 187bhp for these two mainstream variants, hence the rapid 7.1s rest to 62mph time.

The electric motor drives the rear axle, delivering four-wheel drive.

And the battery has a WLTP-rated driving range when fully charged of 26 miles.

There's also a 'trail rated' 'Trailhawk' version at the top of the range that uses the same electrified layout but mates it to the 1.3-litre petrol engine in an up-rated 178bhp state of tune, taking total system output up to 237bhp.

Either way, the power is marshalled by a 6-speed auto gearbox.

The Renegade has always sold on its styling - and it still will.

There are some subtle aesthetic tweaks with this revised model but the main changes lie with the adoption of LED technology for the headlamps and tail lights.

As before, the squarical profile features lovely tight overhangs and some very cool detailing.

What is particularly interesting is the way the design includes some very traditional Jeep design cues but isn't afraid to twist them a bit into something resolutely modern-looking.

That aspect you will either love or hate. Cover up the badges inside the car and, yes, you would probably think you were in a Fiat product, but if you've had a look at the latest Fiat range, that's no bad thing.

Jeep says that the fascia's been updated but it's difficult to see many changes apart from the improved Uconnect touchscreen infotainment system, which on top variants features a big 8.4-inch monitor.

This has clear menus, sharp graphics and useful shortcut buttons, plus it comes with Apple CarPlay and Android Auto, so you can use apps from your smartphone (such as Google Maps and Waze) while driving.

As for practicality, well it's a bit pinched in the back, but then that comes with the territory when you've got this little length to play with.

Out back, boot capacity ranges between 330 and 351-litres, depending on variant.

In the UK, the Renegade is available in a range comprising different trim levels.

For the conventional models, the trim levels are 'Longitude', 'Night Eagle' and 'Limited', with prices starting from around £24,000.

For the e-Hybrid mild hybrid models, choose from 'Upland' or 'S', with prices starting from around £31,000.

For the PHEV Renegade 4xe, it's 'Longitude', 'Limited' and 'Trailhawk', with prices starting from just under £33,000. Standard equipment, even in base 'Longitude' models is relatively generous, including air conditioning, DAB radio with touchscreen and Bluetooth, electric parking brake, 17-inch alloy wheels, tyre pressure monitoring, and remote central locking.

Plus a six-speaker audio system, roof rails, body coloured door mirrors and handles, cruise control, and front fog lamps. The Limited version further adds 18-inch aluminium wheels, chromed exhaust tip, Forward Collision Mitigation, heated front seats and steering wheel, leather upholstery, privacy glass and rear parking sensors.

In case you were wondering where the Renegade is screwed together, yes, it's from the Deep South.

Of Italy though; coming off the same Melfi production line as the Fiat 500X SUV.

The Renegade can't afford to be an expensive car to run, but it rather was in its original petrol forms.

This updated version does much better thanks to its more modern engine rather.

Which starts with the 1.0-litre three cylinder and 1.3-litre petrol units.

The 1.0-litre variant manages 42.2mpg on the combined cycle and 152g/km of CO2.

As for the 1.5-litre MHEV e-Hybrid model, well Jeep reckons that the mild hybrid system delivers up to 15% lower fuel consumption and emissions.

Depending on spec, the Renegade e-Hybrid emits 130-139g/km CO2. That only leaves the 4xe PHEV model.

When fully charged, that plug-in version offers an electrified driving range of up to 26 miles.

Jeep claims that up to 134mpg is possible on the combined cycle when driving in 'Hybrid' mode; and the brand claims a CO2 reading of under 50g/km.

With a typical 7.4kW garage wallbox, you'll be able to recharge in just 1hr and 40 minutes.

Of course, the ultimate figures you achieve in any Renegade will depend very much on how you drive, something you can monitor and improve if you've downloaded the infotainment system's 'Uconnect LIVE' app onto your smartphone.

This gives you an 'eco:Drive' section that enables you to develop your driving style, save fuel and check your car's CO2 emissions in real time.

During each trip, 'eco:Drive monitors four driving parameters: acceleration, deceleration, changing gears and speed variation.

There's also a 'my:car' feature that allows you to check your fuel level and tyre pressure, choose an assistance service if you have an emergency and be informed if there's anything wrong with your vehicle. What else might you need to know? There's an unremarkable three year / 60,000 mile warranty, though you do get three years of breakdown cover included in the deal.

We'd want to opt for the 'Mopar Vehicle Protection' 'Freedom Pack' which extends the warranty to five years and provides competitively priced servicing and assistance plans.

This Renegade has brought a long overdue dose of credibility to the small SUV segment.

Here, you get plenty of style, in a bluff, tough Jeep kind of way, but there's decent substance behind that too, with near-family-sized practicality and the potential for far more off road prowess than any other car in this segment can provide.

So you get a little more than you might expect to from this class of car - which is just as well, given premium pricing that lifts this Jeep well clear of cheaper offerings in the Juke-genre.

If you're OK with that and dig the distinctive look, then potentially, there's much to like here, especially in this improved model with its enhanced electrified engine tech.

The efficient engineering, strong safety standards and hi-tech features you'd want a reasonably expensive family car to provide are here packaged with a depth of character you simply wouldn't think you'd find at this price point.

The result is the kind of car people talk about - the sort almost everyone will have an opinion on, so shy and retiring types should shop elsewhere.

In a sea of compact Crossovers, this one's very different from the norm.

A renegade if you like - perhaps, just as every Jeep should be.
