With the third stage of the Audi Mileage Marathon now complete, the 23 Audi’s reached Vegas readying for the fourth and final leg heading into CA.
The soon to be available Audi A4 with its 3.0L TDI is not just a midsized sedan but a fuel efficient sports car that has proven its worth with a best segment achieved to date of 44.4 mpgUS.
The Audi A4 TDI does not just include a modern diesel engine but carries a whole host of new to Audi, technology meant to stretch the fuel economy envelope of this luxury car far beyond what some may have first imagined. This new Hardware includes a regenerative braking system, a controlled A/C cooling circuit and an on-demand power steering pump.
Weather and terrain has hampered the third legs Fuel Economy somewhat as the Audi’s crossed the Rockies to a maximum elevation of 10,200 feet. Once clear of the Rockies, the pack took a detour through Utah’s Monument Valley and into Las Vegas.
The seven-seat Audi Q7 equipped with the 3.0L TDI is averaging > 29 mpgUS. The Audi Q5 Cross-over with the same 3.0 TDI’s best segment is still 37.9 mpgUS while the compact Audi A3 2.0 TDI's best fuel economy to date is above 47 mpgUS.
