LED Lights: Small Is Beautiful
In just about every new car that comes out, you’ll find LED lighting somewhere around it, whether it’s in the form of daytime running lights, the tail lights or the interior lighting. Car manufacturers seem very proud of featuring LED lighting in the designs. You might be wondering what all the fuss is about. Is this just the latest fashion or is there some real advantage to having LED lighting in your car?
If you have ever started the day with a flat battery caused by leaving the headlights on or a door slightly open or even the passenger reading light on (i.e. all of us at some point), you will have discovered the disadvantages of the old style incandescent bulbs the hard way. Ditto if you have ever had a bulb blow on you at a bad moment. LED lights don’t blow anywhere near as often as incandescents and they also use a lot less power. And that’s the advantages.
Let’s go back to basics. What is an LED light, how does it work and why don’t they blow or use as much power as the invention credited to Thomas Edison? (Historical note: Edison didn’t so much invent the lightbulb as improve it and buy out the patent from the other guys working on electric lighting. The first guy to light a building entirely by electric lights was the UK Joseph Swan. History lecture over.).
LEDs (light-emitting diodes) have been around for quite some time, having been discovered back in the early 1900s when scientists were starting to mess around with this new-fangled electricity stuff. LEDs are semiconductors made from materials like gallium, selenium and good old silicon. Skipping complex explanations about how all types of diode only allow electricity to flow in one direction, what’s special about an LED is that with only a tiny bit of electricity flowing through it (2–3 W), they start glowing.
For the best part of 100 years, LEDs weren’t particularly useful as they weren’t very bright. They lit up in dull red and you could see them glowing if it was dark but you couldn’t use them to find your way from A to B. Other diodes were much more fun in the early part of the 20th century, such as the ones used in crystal (cat-whisker) radios. In the 1960s, people started tinkering with computers and electronics, and found that LEDs were a good way of showing that a circuit was going. They were pretty expensive at first but soon became mass produced and became more widespread. You know those red numbers on timers and other whizz-bang gadgets in movies and TV shows from the 1970s and 1980s? Ditto green lights? Those are LEDs at work.
The fun really started when someone found a way to get colours other than red and green. If the human eye picks up more or less equal amounts of the three primary colours of light (red, green and blue), this is perceived as white. This means that if you shove a red, a blue and a green LED close together, it will look like a white LED. Make your semiconductors out of other materials and you get other colours, including actual white. More tinkering around with refraction by various physicists around the world led to the production of a nice bright white LED bulb and the possibilities really opened up – about 100 years after the initial discovery of LEDs.
There are three reasons why LED lighting is popular for heaps of applications, not just in the automotive world. Firstly, they use next to no electricity, so if you are in the habit of leaving lights in your car on, this won’t drain the battery overnight. It also won’t put demands on your car for extra energy, which increases fuel efficiency (and is even better news for hybrid and electric vehicles). Second, they last for ages. Thirdly, they don’t waste energy in the form of heat.
There’s a fourth advantage, which is more to do with aesthetics: LED lights tend to be smaller, which means that they can be worked into prettier designs (Audi has some nice ones). The fact that LEDs come in different colours also means that you can play around a bit with interior ambient lighting, which is also a lot of fun.
Work is still underway. While LED lights have become bright enough to be used around the home, as daytime running lights and as tail lights (HSV do this well), they haven’t got bright enough yet to be used as headlights… at least not yet.
LED, Xenon and Halogen Headlights
OK, so how do LEDs stack up against the other big two forms of lighting in vehicles, namely halogen and xenon?
Halogen
Pros:
- Cheap
- Common
- Easy to make
Cons:
- Eventually blow themselves out
- Use heaps of watts of electricity
- Waste a lot of those watts in the form of heat
Xenon
Pros:
- Really, really bright
- More energy-efficient than halogens
- Longer lifetime than halogens
Cons:
- Expensive to make
- Take a little bit of time to reach full brightness
- A tendency to dazzle oncoming drivers, pedestrians and cyclists
LEDs
Pros:
- Don’t use much electricity
- No waste heat
- Last for ages if kept at the right temperature (i.e. cool)
- Small size allows more scope fordesigners to make something beautiful
Cons:
- Not bright enough for headlights
- Need to be kept cool, which can be a problem near a traditional internal combustion engine
- Still a bit on the pricey side
Private Fleet Car Review: 2016 Mitsubishi Pajero Sport Exceed
What the Australian car market has known as the Mitsubishi Challenger, for some two decades, is no longer. Enter the Pajero Sport, bringing us into line with the international naming system. Built upon the Triton platform but given Mitsubishi’s “shield” nose job to visually break away from the Challenger, the Mitsubishi Pajero Sport is currently available as a five seater only (the seven seater has been signed off for ADR) and is aimed fairly and squarely at the family.
Complete with a 2.4L diesel and new eight speed auto, A Wheel Thing reviews the top of the range Pajero Sport Exceed.
Straight up, it’s an imposing looking vehicle, standing 1805 mm high. There’s side steps adding to the visual appeal, plenty of chrome up front (burying the headlights in the look), a kicked up rear window line echoing the raked front window and an odd looking tail light design, almost as if the lights have melted and run down the tail gate’s sides.
It’s not as long as it looks though, with a length of 4785 mm making it shorter than Kia’s Optima. It does offer, however, plenty of room inside, with shoulders and legs having plenty of space; 1067 mm front leg room, 880 mm rear leg room, there’s 1022 mm and 1420 mm front head and shoulder room while rear seat heads get 957 mm and 1409 mm. The rear seats, though, sit up higher than the front, which would be uncomfortable for taller passengers that may not wish to take advantage of the DVD screen mounted into the roof lining. The DVD screen is simple to operate, with Mitsubishi tossing in a pair of wireless headphones and a full function remote control as well.
The interior is a step up from Triton, but recognisable as being a family member, thanks to Mitsubishi’s common design themes. The sombre black plastic and seating covering is broken by splashes of brushed alloy look plastic, and there’s there’s the colour display for the driver’s dash binnacle. Ergonomically, there’s the simple and easy to use aircon controls, red backlighting for the steering wheel controls (which are hard to read in the daytime due to the light beige/bronze plastic used) and a seven inch touchscreen complete with digital radio and Android Auto/Apple Car Play app connectivity plus external HDMI input. What it doesn’t offer is satnav, only offering GPS, relying on the app to supply mapping. If you take the car off road and out of mobile range (easy to do with some providers, then GPS only won’t cut it.
There’s heating only (grrr) for the front seats but they are both power adjustable. The tail gate, though, is not and it also has one of the numbest feeling opening mechanisms A Wheel Thing has come across. It’s literally the same as a door not closed properly, such is the lack of pressure required to open the door by using the handle. Certainly the lack of a power ‘gate stands out in this class.The seven seater version will, apparently, have the second row seats fitted into the cargo bay’s undercroft, where the spare wheel would normally go. This allows the Pajero Sport to keep the 673 litres of rear cargo space with the current rear seats up, which increases to 1624 litres when folded (they tumble fold as well).
There’s also curtain airbags, a driver’s kneebag and the usual onboard electronics as well, such as Active Traction Control, Active Stability Control, Hill Start Assist, ISOFIX rear seat mounts, plus there’s a centre and rear diff lock for off roading.
Out on the road the Pajero Sport is an adequate performer on tarmac. The 2.4L diesel feels as if it’s perhaps too small for the 2070 kerb mass it needs to move but there is 430 torques at 2500 rpm, good for 3100 kilos of towing. It’s almost a situation where acceleration is not a word seen in the same sentence as alacrity. To clarify, that’s acceleration off the line, as mid range get and go is reasonable, without being startling.
Yes, there’s paddle shifts, but they make no difference in change of speed for the transmission whereas some cars have a substantial difference between self shifting and manual changes. The changes themselves are smooth and the transmission kicks in for engine braking downhill, as well. Certainly, having the extra cogs do make a difference to the drive, with freeway velocities seeing around 1700 rpm.
Fuel economy with Mitsubishi is flexible: their onboard system gives a real time indication of usage, rather than an average, with the figure showing over 14.0L per 100 km when taken off road and used in low range to just over 8.0L per 100 on the freeway run back to the dropoff point. What’s a touch worrying is the comparatively small 68L fuel tank fitted to deal with Mitsubishi’s claim of 8.0L/100 km for a combined cycle.
Handling? Not fantastic and not helped by the compromise 265/60/18 on and off road rubber, to the point that an incident was almost had on a left hander as the tyres lost traction. It took a long moment before the electronics kicked in to help sort out the (potentially un-fun) situation. It’s a touch soft and prone to some body roll on normal roads, yet crashes on some pothole and speedbumps. Odd. The steering is numb on the straightaway, takes a bit of a turn either side before there’s any bite and does tend towards understeer most of (well, all) of the time in 2WD, and only slightly less so in 4WD H. Turning circle is tighter than the rest for the class, at 11.2 metres.
Bear in mind it’s a four wheel drive capable vehicle and seemed to tighten up in handling when the drive mode was changed from 2WD to 4WD high range. The aforementioned incident was also in 4WD high. It does seem, however, that the Pajero Sport’s forte’ is off road. Taken to A Wheel Thing’s standard off road test track, a mix of mud, gravel, rock and sand, it tested the Pajero’s off road drive and the switchable programmed modes, being all of the former plus Snow. Is it any good?
With a proper transfer case (although somewhat recalcitrant in engaging via the control dial), once the drive finally decides to finish thinking, it’s an… engaging drive. It powers through puddles (it has a wading depth of 700 mm maximum), clambered over rocks, crawled down gravel and rocky slopes (utilizing the crawl function programmed in) nicely and essentially made its on road manners look even worse. Yes. It’s good.
For its off road capability alone, it’s worth the buy for those that like to get dirty. There’s a 30 and 24 degree approach and departure angle, 218 mm ground clearance (unladen), and will climb a 45 degree slope. For downhill runs, the Hill Descent Control works admirably, easing the two tonne plus machine down cautiously, with a little huffing and wheezing from the brake system, but easily as well.
At The End Of The Drive.
It’s a three model range, the Pajero Sport, with GLX and GLS sitting below the Exceed. There’s a price spread of $46990 to 54990 plus ORCs. It’s a well priced range and certainly a range full of value. It’ll have even more of a broader appeal when the seven seater arrives, sometime before June 2017.
The new look also, hopefully, points the way towards a new Pajero, something the cash strapped Japanese maker needs, along with a new Lancer and ASX range.

Private Fleet Car Review: 2016 Subaru Liberty 3.6R Sedan
Subaru’s Liberty sedan is an unsung hero in Subaru’s fleet, with the Outback and WRX getting all of the eyeballs That’s a shame because it’s big, roomy, nice to be in and not unattractive to look at. When the 3.6 litre boxer engine is slotted into the engine bay, it then becomes an entrant in the large car class, against Aurion, Commodore, Falcon…and so it should. In February of 2016, A Wheel Thing attended the launch of the updated Liberty, Forester and Outback and recently sampled the 2.0L diesel and 3.6L petrol powered versions of the Outback Premium.
The Liberty sedan with the 3.6L is, effectively and essentially, the same as the Outback wagon, bar the extra ride height and sheetmetal. It certainly has the same excellent ride quality and handling, with a lot to be commended. Of note were the subtle changes to the suspension in the wagons. It’s A Wheel Thing’s opinion that the Outback is one of the best in the medium wagon class for ride and handling and the Liberty sedan slots right in there. There is a bit of competition out there such as the Mondeo, Superb, and Octavia, just to mention a couple, but the incremental development work that Subaru Japan and Subaru Australia have jointly been involved in has paid off.
Tested on dirt and tarmac roads in South Australia during the launch, and driven hard in its most likely environment, suburbia, both sedan and wagon exhibited the kind of ride a discerning driver looks for. On undulating roads,there’s no sense of continuing the motion, with the Liberty Premium simply following the up and down movement while simultaneously isolating the cabin from it.
Shopping centre car park speedbumps were ignored, with only the barest thump transmitted through at low speed (say two or three kmh) and at around 20 kmh there was a short, sharp, jolt which was instantly damped. The larger rubber based units on some back roads were noticeable in the relative lack of impact felt inside, with the compliant suspension taking up most of the shock and minimising any bodily movement. It’s well tied down and lacks the floatiness found in others.
It’s also quiet on the road with tyre, road and wind noise very quickly becoming forgotten. This helps in regards to fatigue on a drive, as does the ride quality. It’s a tight handler, with just a hint of understeer in slow 90 degree corner turns but tucks the nose in nicely in roundabouts. Steering is responsive, perhaps moreso in the 3.6R, with the load building up left and right from centre in a progressive manner.
The transmissions provided were CVTs for each, programmed for six speeds with the 3.6R feeling more like a traditional auto. There is a manual option available, as well as a 2.5L four potter. The range starts at $35990 for the entry level 2.5L with CVT with the range topper 3.6R at $48490.The diesel premium CVT is $44490, with that price being an increase of $1500 over the outgoing model whilst the 3.6R seeing an increase of just $500. A Wheel Thing has not been a fan of CVT, for the most part, as the CVT added to the WRX is simply superb. There’s a discernable lag in acceleration, a lag in switching from Reverse to Drive before forward motion is engaged, a lack of smoothness in doing so as well. The 3.6R’s gearbox however is zippy, instantaneous response is given when asked for, and there’s more of a sense of the engine working firmly hand in hand with the gearbox.The 3.6R is more free spirited in its revvy nature, seeing 191 kilowatts at 6000 and showing no restraint in how it spins. There is the question of economy, with 9.9L/100 km for the 3.6R, however final figures finished well under that figure, at 8.5L/100 km.
What is impressive about the 3.6R’s delivery is the torque; although peak torque is at around 4500 revs, there’s something in the order of over eighty percent available from 2500, meaning there;s plenty of low end response and urge to keep the Liberty motivated.
Apart from the all wheel drive system marketing that Subaru has steadily built its following on, there’s been the step by step increase in standard technology. The 3.6R gets the EyeSight package, with stereo cameras and also now with colour recognition programming. The 3.6R also gets the Vision Assist package, giving the driver: Blind Spot Monitoring, Lane Change Assist, Rear Cross Traffic Alert, high beam assist and self dimming rear vision mirror.
The colour recognition shakes hands with the ACC, Adaptive Cruise Control, by recognising brake lights being activated in vehicles ahead, and will slow the Outback. It’ll also recognise lane changing vehicles ahead, adding to the five star safety rating the range has. A very handy feature is what’s called Unintended Start Prevention, where it’ll hold the vehicle if the accelerator is pressed but the sensors read an object in front of the car.Subaru have also tossed in the Euro style emergency brake light system, which flashes the brake lights when the computer senses input that would be an emergency stop situation. The interior of the 3.6R Liberty sedan is identical to the Outback wagon with the 3.6L, down to the sunroof, somewhat slabby seats, lack of detail on the leather, no cooling for the pews (surely a must for Aussie spec cars with machine made leather seats?), the SI Drive system (which changes the engine mapping and shift points in the autos), the StarLink touchscreen satnav and infotainment system…you get the picture. A Wheel Thing still feels the location of the clock has it lost within the aircon controls, not exactly an ergonomic or safe feature…Of course you’ll get Bluetooth handsfree phone connection, audio streaming and, being wagons, plenty of storage space in the cavernous boot, with over xxxL of cargo and enough bottle holders to suit the family.
You’ll get curtain airbags, side airbags, driver’s knee airbag, power seats and that all wheel drive system with its so user friendly handling.
The exterior hasn’t come in for any major do-overs; there’s a new Dark Blue Pearl paint (verra noice) and a retrimmed grille for the 2.5i and 3.6R aside from the aforementioned driving light change. It’s a handsome looking vehicle, with good looking 18 inch alloys and 225/60 Bridgestone rubber. It’s a good size overall, too, with a total length of 4815 mm encompassing a wheelbase of 2745 mm and tracks of 1570/1580 mm. .
At The End Of The Drive.
Subaru’s Liberty really is a hidden gem for the niche player from Japan; the brand had a massive 344.7% sales increase in 2015 though. There’s a three year warranty on offer, which some would say lacks compared to some of the other brands out there. But the brand has a strong, fiercely loyal following and there’s little doubt an extra year or two warranty makes little difference to that loyalty.
What the Subaru Liberty trades on is a good look, solid engineering, dependability and with the 2016 model, some of the best handling in its class, with the MacPherson struts and double wishbone rear. It’s a pity the CVT nobbles the diesel compared to the 3.6R as the economy of the diesel will always be a winner there but the 3.6R wins thoroughly in the performance stakes.

Road Rules That Time Forgot
Driving a car seems to be, for some people, one of the hardest things to do. Not necessarily the act of driving itself, but some of the legal requirements that will make your drive, and theirs, safer.
Some surveys state that the number one peeve of drivers is others that don’t indicate. That’s a fair point, as far too many drivers don’t do that on the straight road but did you know it’s also a requirement when merging from a freeway/highway on/off ramp? It also ties in with the relatively simple yet seemingly over complicated act of merging.
Here’s how it should work: you’re on the merge lane and the road you’re coming to is on your right. The first thing you should be doing is be looking for the traffic that will be coming up behind you. This is where the law AND common sense come into play. Indicate right; not once, not twice, but until you’ve entered the left hand lane from the merge lane. At the same time you should have either accelerated or slowed in order to “zip merge”.
A tip: if you’re on the highway and coming to a section where it’s clear there’s a merge lane, move right, allow the incoming traffic to do so with a higher safety factor.
By setting up your approach speed correctly, you’ll aid in keeping the flow of traffic up plus, by using your indicator, you’ll give plenty of warning to the highway or freeway traffic and you may even see them do the right thing and move right.
Another road safety tip involving indicating is when you pull over or leave from a roadside location. Let’s say you’ve just got a call on your mobile phone and you haven’t got it bluetoothed to your car. It’s a call you need to take; when pulling over to the left, onto the verge and off the road, indicate to show following traffic you’re doing so. When ready to continue, it’s a legal requirement that you indicate right BEFORE entering back into the flow of traffic.
Wet weather driving seems to be more fraught with danger than what it should be. The simplest safety tip you can take advantage of is to ensure your headlight switch, if fitted with Off/Auto instead of Off, is to switch it to Auto. It’s also legislation that your headlights should be switched on once it’s sunset however there’s good sense in having them on anyway. The New South Wales Roads and Maritime Services says:” Headlights. In many daytime situations driving with your vehicle’s headlights on can improve the likelihood of being seen by other road users. This applies to both country and city driving situations. Your headlights must be on when:
Driving between sunset and sunrise
At any other time when there is not enough daylight to be able to see a person wearing dark clothing at a distance of 100 metres.”
If your car has driving lights fitted, as most modern cars do, they’ll be visible to the cars in front but your tail lights won’t be on until the Auto function kicks in or you move your light switch to the next setting. Simple, and safety is raised.
Finally, a hint on roundabouts. These are, surprisingly, seen as a complex item to deal with but here’s how to make them easy to live with.
If it’s a roundabout that is a four way entry and exit and you wish to go left, you indicate left. If you’re going straight ahead, you indicate left once you’ve reached the half way point between entering the roundabout and exiting. If you’re going right, you indicate right as you enter then left to show you’re exiting. The same applies to all three way roundabouts.
