Two new gas sipping engines have been released for the Audi A3 lineup. Would you believe the more powerful unit is also more efficient? Cool.

Audi has introduced two new engines options for the Audi A3 line-up.  The two engines are to give customers more options for those customers whose number one concern is fuel efficiency.

Both are 1.6-liter four-cylinder TDI units new customers will be able to select.  The first is a 90 hp engine with a peak torque of 230 Nm, emitting a scant 118 grams of CO2 per km.  0-100 km/h time is 12.9 seconds in an A3 with this engine, and a top speed of 180 km/h.  Using only 4.5 liters of diesel per 100km, or 52.27 US mpg, you might be pleased with cleanness of this choice.

But the second unit is not only more powerful, but more efficient, too.  Rated at 105 horsepower, this four-cylinder engine uses just over 4 liters of diesel for every 100 km of driving.  This translates to a spectacular 57.37 US mpg.  Even emissions are cleaner with this unit, dispensing only 109 g/km.

The secret to this engine's success is the use of both energy recovery and a start/stop system.

With the 105 hp unit, the Audi A3 gets a 0-100 km/h time of 11.4 seconds, on its way to a 194 km/h top speed.  Unfortunately, torque figures were not released for this engine.

The Audi A3 1.6-liter TDI is available for order now.  Customers who select the 90 hp unit will spend €22,550.  Stepping up to the cleaner, more powerful engine will cost an extra €1,000.  Choosing an Audi A3 Sportback model will cost an additional €900.  It is unclear if these prices include or exclude taxes.
