Audi will introduce several technologies by mid of 2009. This will include a stop and start feature and energy recovery through the brake system.

The stop start system will just be like what others have developed. The system of the car will be off when the vehicle stops and the clutch is released. The engine will be turned on again once the driver engages the clutch. This technology is not yet available for the automatic transmission coupled engine.

The stop start system aims to reduce the carbon dioxide emission by 5g/km and about 0.2L of fuel for every kilometer. Audi will first use this technology on the A3 TFSI 1.4, 2.0L A4, and the A5.

The brake system with energy recovery will be first seen on the manual transmission Audi A3 1.4 TFSI, A4, and the A5 both on the basic and Cabriolet. It is also used on Q7, Q5, and the Audi A6.

The car manufacturer will also make use of a modular efficiency system which basically will encourage drivers to be more efficient while behind the wheels. This will be done through a series of feedback channels that will give the driver relevant data about fuel consumption.

The new Audi cars will also give the driver a cue when to shift the gears. About 30% of  fuel efficiency can be attributed to the different driving habits of different individuals.

The proposal urges automakers to have a fleet average of 35.5 mpg when the proposal is set into law, a standard which is 10 mpg higher that today’s rules. Obama also proposed a cut on carbon emissions from vehicles which play a major factor in worsening global warming.

Car manufacturers hear the gunfire at the starting point of a race to make lighter vehicles and efficient car engines like diesels and hybrids to meet the new guidelines. Experts point out though that the new call for better standards will have a $600 top up in the cost of production of every vehicle.

Looking from another vantage point, the US will be able to save 1.8 billion barrels of oil by 2017. The assumption is based on the average daily consumption of the US market of as much as 20.7 million barrels per day. The savings is equal to about 87 days of US oil usage.

Under the Bush administration, the 35 mpg mark is a goal set to be achieved at least by 2020. The call for better fuel economy comes on top of the March 2009 standards. The March guidelines set the 2011 vehicle models to have at least 27.3 mpg fuel mileage which is 8% better than today’s standards.

Car manufacturers have been opposing new fuel efficiency standards but have settled to agree to the new goals as they will have guidelines effective in all states with California included. Currently, automakers follow a separate guideline for the standards by the state of California. Legislators from California have agreed to follow the proposal from the federal government.
