Porsche Battery – a mere £1200

The rather expensive Porsche Lithium Ion Battery Car batteries have been roughly the same shape and size – and utilised basically the same lead-acid technology – for years. They’ve got better, as you no longer need to top them up with distilled water at regular intervals (I’m showing my age now), and they are less prone to going flat. But that probably has more to do with alternators replacing dynamos than the batteries themselves.

Jaguar XJ Review (2012): 3.0 litre Diesel Portfolio LWB

We’ve had the latest version of the Jaguar XJ in for review – the LWB 3.0 litre Diesel Portfolio with Sports Packs – to see how the XJ is maturing. It’s getting on for two years since we had the first Jaguar XJ in for review, and almost three years since we first saw the new XJ at the Saatchi Gallery in London, almost a year before Jaguar managed to get their new range-topper in to showrooms. In between we had a long-term XJ in for review which was with us for four months and proved to be far more reliable than the early car we had in – which did have problems – and a car we covered most the UK in with almost nothing in the way of hiccups.

They had expected to see Lewis Hamilton in the Mercedes McLaren waltz to a win, but had to settle for simply powering the world champion – Jenson Button – to victory this year and claiming third and fourth place at the inaugural Abu Dhabi Grand Prix.
