IMAGINE the scenario: It's Sunday morning and you've been looking forward for the chance of a sleep-in after a hard week in the office.

Suddenly there's a roar loud enough to waken the dead. Yes, your gosh-darned next door neighbour has fired-up his hulking great V8 ready for an early-morning blast.

But there's good news for anyone living next door to owners of the new Ford Mustang ⦠the latest version of the iconic US sports car comes with a new feature which should enable the neighbours to enjoy a restful Sunday morning in bed.

Called Good Neighbour Mode it allows drivers to tone down the V8's roar depending on driving conditions and the time of day.

According to a recent poll in the USA, loud engine revving ranks among the most annoying noises neighbours make, alongside other common nuisances including power tools, barking dogs and band practice. Only early-morning lawn mowing is more despised.

So Ford has come up with an active valve performance exhaust system for the new Mustang, which automatically adjusts the decibel level of the exhaust note according to the different drive modes, from Normal and Sports up to Track mode that emits a satisfying 82 decibel growl.

The new Mustang's "Good Neighbour Mode", or Quiet Start even enables drivers to toggle through a menu in the instrument cluster to select the sound they want. For example, between 8 p.m. and 7 a.m., drivers can keep the peace by scheduling their car to start, minus the roar.

It's one of a host of high-tech features built into the latest version of the Mustang which is sleeker, faster and more technologically-advanced than before and comes with more athletic styling, sophisticated engine and suspension enhancements, advanced driver assistance features and more customisation options.

The Mustang's awesome five-litre V8 engine now delivers 450 PS - and is able to sprint from 0-62 mph in 4.3 seconds when combined with a new 10-speed automatic gearbox. The latest six-speed manual transmission features rev-matching technology that delivers smoother, faster downshifts accompanied by a "blip" of the powerful engine.

While the throaty V8 remains the engine most associated with the Mustang, the more fuel-efficient 2.3-litre EcoBoost petrol turbo engine will continue to be available.

There's a sophisticated new adjustable suspension system and selectable drive modes, including a new customisable My Mode option which will allow the driver to programme his preferred settings for performance, dynamics and exhaust sound , while other driver aids will include a pre-collision assist system with pedestrian detection and a lane-keeping aid.

Right hand drive versions of the latest Mustang will be available in April with prices for the manual models of £35,995 for the 2.3 litre fastback and £41,095 for the V8. Convertible models are priced from £39,495 (2.3) and £44,595. Opting for the 10-speed auto adds £1,600 to the price of 2.3 litre models and £2,000 to the V8.
