Off the line…

Posted on October 19th, 2007 in Driving Emotion,Holden,Mitsubishi,Power by Julian Edgar

The week that I am writing this we have two press cars. It’s unusual to have two new cars simultaneously; in fact, it’s something I normally strive to avoid unless I am interstate for a period. Then it’s OK because those cars are usually not able to be obtained in my home state – so better to work harder for a short time in order to sample more.

One of the cars is a Mitsubishi 380 VRX 5-speed manual and the other is an automatic 5-speed Holden Epica 2.5.

Both are front-wheel drive but the 380 has 175kW and 343Nm in a body that weighs 1590kg, and the Epica has 115kW and 237Nm and weighs 1500kg.

Clearly, then, the VRX is going to be the faster of the two cars, not only because of its higher flywheel figures outweigh the slightly greater mass but also because its manual transmission has less losses than the Epica’s auto trans.

But is the VRX faster? Not a test in the world is going to show the Epica as being faster than the VRX (or the equivalent in other comparative cars) and yet as is so often the case, the power, torque and mass figures tell a story that is massively incomplete…

It so happened that my wife and I ended up in driving the two cars at the same time. I was in the Epica, she in the VRX – and in front of us a red traffic light. Both in pole position – and when the light turned green, we went for it.

Trouble is, the Epica was ahead all the way to 80 km/h…

Next red light, Georgina got a better launch – but she still took until 60 km /h to get past the Epica.

Simply, the power and torque of the 380 was so great that the traction control kept shutting down the engine as wheelspin occurred.

The same story could be repeated with lots of different cars – those with auto transmissions and insufficient power to break traction (or, to put it another way, a lower torque curve that extends further up the rev range) can be very quick off the line in real world conditions. On the other hand, manual trans cars with bulk off-the-line torque can be relatively slow.

I remember the disbelief when former colleague Michael Knowling wrote of an STi WRX that a Corolla was quicker away from traffic lights; an absolutely true story symptomatic of the STi being the opposite case to the VRX – no bottom-end torque at all…

No matter what figures might show, for real-world quick getaways, very little beats an auto trans matched to an engine that won’t spin the driving wheels.

Will the VE Commodore prove me wrong?

ve-commodore.bmpMost of our Australian readers won’t be old enough to remember the release of the 1978 VB Commodore – and to be honest, at the time I wasn’t taking much notice of cars myself. However, it was common contemporary lore that the VB represented the new, small and modern family Holden while Ford, with the XD Falcon, persisted with the larger, outmoded type of traditional family car.

With the increasing price of fuel, it appeared that Holden was onto a winner with the Commodore.

But in fact they weren’t onto a winner at all: the VN model of a decade later went to a larger – especially wider – body, initially perched on the narrow track of the previous series.

Most pundits would have thought – and in fact did think – that Holden was heading in the right direction with their smaller original Commodore. It seemed the correct car for the times and in comparison, the face-lifted XC that became the XD looked like a big mistake. (In fact, a few years after this, I can remember looking at an open XD wagon and wondering who on earth needed a load area so enormous.)

But new car buyers didn’t agree with the smaller VB-VL Commodore strategy – Holden would have sold more Commodores if they’d stuck with the larger body all the way through.

One reason I don’t think much of the Type R Civic…

type-r-on-dyno.jpgToday I returned Honda’s Type R Civic to the Queensland office. I am quite happy to see it go: I think the Civic Type R is a pretty weak car – something I make clear in our road test that will appear in AutoSpeed in due course.

With a 2 litre naturally aspirated engine that revs to 8000 rpm and develops 148kW, it might look the goods on paper – but the reality is very different.

To go further, I think the idea that small, naturally aspirated engines can compete with turbo cars is the stuff of fairytales.

The Peugeot 206 GTi 180  and Ford Focus ST170 were similar cars in concept to the Type R Honda – all based around the idea that naturally aspirated, high revving engines have some intrinsic advantage over their forced induction competitors. That’s a purported advantage over turbo competitors that have more peak power – and vastly more average power through the rev range.

Jumping ship…

epica.jpgAs we all know, successive models of the one car tend to get larger.

A Corolla is now bigger than the original Crown; the new-age Mini is vastly bigger than the original; the current VE Commodore is very much larger than the first VB model.

Bigger is apparently better, until the size has grown so much that there’s a created place for a new, smaller model – like in the Corolla’s case, the Echo and then the Yaris. (Or in the Honda Civic’s case, the Jazz – there are many examples of the phenomenon.)

But the Holden Commodore has proved rather problematic. The newer, smaller models designed to slot in where the Commodore once was have not been very successful – the Vectra being the expensive case in point. So now we have the much cheaper Epica, which in terms of cars like the original sized VB-VL model Commodores, is actually large indeed. (But despite its size, it’s still smaller than the current VE Commodore…)

So what does it take for a long-time Commodore owner to finally jump ship? You know, the older person who has driven Commodore models continuously since their 1978 release? (For Commodores and Falcons, it wouldn’t surprise me if people in the ‘have-always-driven-them’ category make up half of the current private buyers.)

Do these people just religiously follow the upgrading in size, the upgrading in power, and the upgrading in weight? Or at some point, perhaps now with children having left the nest, do they say to themselves that the new iteration of the model simply doesn’t suit, and it’s time to get a car that isn’t smaller than their current model – it just isn’t yet again bigger. To step out of a VZ Commodore, not into a VE but into an Epica, for example.

Real world family car driving

Posted on April 21st, 2007 in Mitsubishi,Opinion by Julian Edgar

2960_6mg.jpgIt seems like only yesterday that the Mitsubishi 380 was released, but time is no friend to a car company – not when the Toyota Aurion and VE Holden Commodore have both since seen the light of day. Throw in the still highly competitive Ford Falcon and the pretty-well-just-as-big-inside Toyota Camry – and of course the highly impressive Hyundai Sonata V6 – and you have what can only be called a very difficult market for the Mitsi. Not to mention the fact that public uncertainty over the future of the local manufacturing plant has assumed almost TV soap opera proportions…

The result is not unexpected: at the time of writing, you can buy a Mitsubishi 380 with less than 10,000km on the clock for under AUD$24,000. Expect that to soon dip below $20K – and for a fearful rate of depreciation to follow. To put this another way, if you expect to keep a car for a long time (say 10 years), you can now step into a fast, excellently handling, and near new family car for what can only be described as an astonishing bargain price. Well, that’s what I think the car is.

But what’s it actually like in a family role, child seat in the back and mostly doing the humdrum duties of urban travel and shopping centres, with just an occasional longer country trip thrown in? My wife, Georgina, recently spent three weeks in a 380 ES 5-speed auto, a car with 30,000km on the clock. She drove the car with Alexander, 2, in the back. Georgina normally drives a Toyota Prius and has driven the current Sonata, Falcon, Commodore, the last of the Magnas, and many other cars.

Here are her comments.

A Rocky trip

Posted on January 13th, 2007 in Economy,Honda,Hybrid Power,Opinion by Julian Edgar

I write this after completing two 750-kilometre drives, each done in a day. The occasion was the wedding of some friends, and the location was the Rydges resort at Yeppoon, on the coast near Rockhampton in Queensland. My wife and son flew up from the Gold Coast where we live; I decided to drive.

The car was my 1-litre, three cylinder hybrid Honda Insight. But isn’t that a long drive for a little car? Perhaps – but so what? There’s plenty of cabin space (in fact, with the seat adjusted correctly, my left foot can barely reach the firewall) and I don’t have any problems with driving a low-powered car on the open road. In this era of very powerful base model Australian cars, people tend to forget that safety on the highway is much more dependent on driving skill than the acceleration available under the right foot. I didn’t have any problems overtaking a few semi-trailers or climbing hills at the speed limit – and I saw lots of very powerful cars that had near misses, simply through appalling driving.

The only changes I made to the car for the trip were to inflate the tyres to 37 psi (hot) and fill the tank with 98 octane fuel. I think as a result of one or both of these, fuel economy was even better than standard. Well, it would have been if I hadn’t run the air con for about 80 per cent of the time….

After resetting the trip computer fuel economy display at home, my first stop (the petrol station to fill the tank) showed a fuel economy of 2.2 litres/100km (most of the trip to the petrol station is downhill), followed by 2.7 litres/100km at the Gateway Bridge and 3.2 litres/100km at Gympie. Following that, I turned on the air and the road also became hillier: the consumption average then steadily rose to 3.5 litres/100km where it stayed for the rest of the trip, including the full return journey.

As I have said many times before of this car: that’s world’s best fuel economy.
