The German premium brands are certainly putting their workhorse 2.0 liter diesel engines to the test these days. Doing their best to up their overall economy/emissions ratings by placing ever-improved versions of those light drinkers into their compact and medium-sized sedans.
The latest is Audi, who's A4 2.0 TDI e claims a mileage rating of 4.6 liter/100 km, or more than 50 mpg US (51.13 mpg, to be exact) and CO2 emissions of 119 g/km.
With the "e" likely standing for "efficient," the A4 2.0 TDI e comes with VW Group's standard 2.0 liter engine with 136 bhp but tweaked for better fuel economy. It features stop-start technology, an onboard computer that coaches the driver to maximize efficiency and a 6-speed manual transmission with a raised final-drive ratio which reduces engine speed in each gear.
The A4 Avant model will also be available as an "e" model with the same engine.
Oh, don't let that 50 mpg US rating fool you about a North American release for this A4 "e". Audi is just boasting about cracking that milestone. This Audi isn't headed to the US market to go up against the 50 mpg Toyota Prius, although it should. The A4 2.0 TDI e is a European model and it is not (yet) scheduled for a US release.
The A4 2.0 liter TDI e goes on sale in early June with a starting price of 30,800 euros.
