Petrol cars twice as likely to fail MOT on emissions

The latest MOT test data shows that 26.2% of all cars tested fail on excess exhaust emissions – and surprisingly petrol cars fail more than twice as often as diesels in this part of the annual roadworthiness test. According to the official Vehicle Operator and Standard Agency (VOSA) figures, which cover all of 2010 and the first nine months of 2011, 9.7% of petrol cars failed to meet MOT emissions standards compared to just 3.9% of diesels.

Mazda CX-5 gets new trim levels

Mazda CX-5 gets new trim levels When car makers come up with trim specifications for their models, they do so in a way that gives easy stepping stones in equipment levels, from hair shirt to over the top. They also expect that many buyers will pay a visit to the options list to add in a few extra goodies to the standard spec, but it looks like Mazda has been getting the same request repeatedly from buyers of the CX-5 compact SUV – give us a sunroof and leather. Until now, the only way to get sunroof and leather was to opt for the range-topping Sport trim – which costs from £27.5k – but now Mazda has added two trim levels beneath the Sport - SE-L Lux and SE-L Lux Nav – which come already equipped with the two most requested extras.
