To a great extent, LPG has been sidelined as a fuel since the government retracted its support and enthusiasm for the fuel. But that hasn’t stopped Birmingham City Council including LPG as part of its low-carbon transport policy for the future.

Mark argues that, while some commentators have scoffed at Birmingham’s support for an ‘old’ fuel, there could be many benefits. I called Mark to talk to him about his views.

“Fuel is a really big story and one that I think will come to dominate over the next 10 years. We try to get people to see that the cars they buy now will lock them in to fuel efficiency levels (and tax levels) for the next three to four years,” Mark explained.

“The landscape for cars will change beyond all recognition over the next 10 years (probably the fastest pace of technological change the automotive industry has had since in started 100 years ago).

“This is only two to three car changes away.

“There are so many options in terms of fuels – and technologies – that it is important to keep some element of flexibility in a fleet to cope. I think there is a real rationale here for taking cars on a three year cycle and backing away from the (recent) trend of four year terms.

“People should be able to buy into the technology as soon as they can. Who would have thought even a year ago that a 320d would be capable of 70mpg and crack 109g/km CO2 and still be just as quick when you want it to be!”

It’s a good point. I’m always sceptical of businesses that tell you they must buy diesel. Why? Look at how you use the car – what’s the purpose? Just because received wisdom says diesel is correct for company cars doesn’t mean received wisdom is correct in every case.

If you have several salesmen that belt around the country then a diesel would be appropriate for the mileage. But for a staffer with a lower mileage, then petrol might well be more appropriate.

Anyway, have a read of Mark’s blog – it’s a thought-provoking piece. As always.
