CAR tech: who's to blame for your car's terrible fuel economy?

In early 2013 Audi lost a case brought by the Advertising Standard Agency (ASA) because of ‘misleading’ fuel economy figures used in an advert, after a customer complained they couldn’t get anywhere near the 68mpg quoted. The court case once more exposes the yawning gap between officially sanctioned mpg figures and those experienced by owners. A recent study by the Independent Council on Clean Transportation (ICCT) looked at cars sold in the UK and Europe, and discovered the difference between official mpg figures and real-world driving had grown from 8% in 2001 to a barely believable 21% in 2011.

Hertz brings back rent-a-racer program with Dream Cars

G25 axed from revised 2013 Infiniti lineup

Infiniti will trim the G sedan model lineup for the 2013 model year while adding some extra power to the EX and FX crossovers in the form of the 3.7-liter V6 found in the G37. Per Infiniti's naming conventions, the EX35 and the FX35 will become the EX37 and FX37 when the 325-hp, 3.7-liter V6 is slotted under the hood. The result is a 28-hp gain over the current 3.5-liter V6.
