With strict new emissions standards looming in both the US and Europe, carmakers are hard at work developing new initiatives to curb tailpipe emissions and lower fuel consumption. One of the trendsetters is Audi, which hopes to build the world's cleanest diesel engine and at the same time be the first automaker to offer a diesel model that meets the forthcoming Euro 5 emissions standards. It plans to launch a new range of ultra-clean and efficient TDI engines from the middle of next year, which will offer the same pulling power of today's versions but with even lower fuel consumption and emissions. One example is a 3.0L V6 that develops 240bhp and a massive 550Nm (495 lb-ft) of torque.
