The Extra Mile

If you’re anything of an enthusiast of driving for economy, and a keen fan of this column, you’ll know that the energy in the fuel we use is dispersed as heat, in one form or another. Overcoming air resistance ends up heating the air, the energy dispersed in braking to slow down is turned into […]

The Extra Mile

I guess that we all, at times, get stuck in a bumper-to-bumper convoy where the car at the front is someone who, arguably, quite rightly, has chosen a lower cruising speed than suits most of those stuck behind. On roads where opportunities to overtake are few, and when some of those in the convoy have no […]

The Extra Mile

With the good Doctor having addressed some of the realities of electricity supply and the practicalities of charging electric cars in Issue 391 “How it Works”, it’s not inappropriate for us to take a look at the cost side of the subject in this column. How, in the vastly different world of electric power, might […]

The Extra Mile

If there’s one thing as a motorist that really cheers me up with the arrival of the warmer months, it’s seeing the water temperature gauge moving off its stop a lot sooner after a cold start-up than in the winter. Of course that means getting more energy out of every gallon of fuel, a quicker […]

The Extra Mile

When we think about saving fuel, and driving to save fuel, one of the significant factors involved is too often glossed over, and that’s the origins, the quality, and specification of the fuel that we are using. How much difference can there be between different fuels from different sources? Well, we have it on good […]

The Extra Mile

It’s a challenging time for diesel owners, assaulted regularly as we are in the media, and by the medical experts, for the noxious gases that our engines emit, and threatened with exclusion from city centres, or with heavy charges whenever we might need to enter them. So there is undeniable pressure to consider alternative power […]

The Extra Mile

Let’s take something of a drive into the future, and consider the principle of economy driving when cars have become electric, and potentially fully autonomous. Maybe general attitudes will be that electric cars are very efficient and economical, and the energy they use so cheap, that saving fuel won’t really be considered relevant. Range and […]

The Extra Mile

Let’s look at one of the fundamental issues of car buying, manual or automatic? Most of us know about using the right gear for the right speed, but it’s not quite as simple as that, as it also depends on the power required from the engine in any given situation. Many drivers take a view […]

The Extra Mile

Overtaking, inevitably, often becomes necessary in normal motoring, and it rarely helps your fuel economy, although there are some situations when it actually can ñ such as when it lets you escape from being stuck behind a driver who stops at every roundabout and slows excessively for every slight bend in the road. But overtaking […]

The Extra Mile

A reader letter, from Mr P.Walsh, in response to my column on preparing for winter motoring in issue 383, creates the subject matter for this month ñ engine pre-heating. For decades (but alas, no longer) the noble British company of Kenlowe offered British motorists the facility of after-fit 3kW coolant heater units, with pumped coolant circulation, […]
