Come this fall, Volvo's range of engines will be bolstered with the addition of two new mills that feature a wide variety of the currently available mileage-enhancing tricks and power-boosting techniques. The engines, dubbed the T3 and T4, border on tiny with each mill displacing just 1.6 liters.

Both the T3 and T4 make due with just four-cylinders, but the addition of a turbocharger and

While Ford is working on plenty of hybrid and electric vehicles, its big bet for meeting the new corporate average fuel economy standards is EcoBoost, and so far customers appear to like it.

The next generation of BMW's 5-series sedan is expected to debut early in 2010, perhaps at the Geneva Motor Show. The new M5, however, likely won't be launched until the 2011 Frankfurt show. According to Albert Biermann, development boss of the M division, when it does arrive, it will cut CO2 emissions by 20 percent compared to the current model.

Hybrid and battery electric cars get most of the attention from drivers looking for more efficient transportation. Toyota has done a masterful job of marketing the benefits of hybrids and, for a great many people, hybrids are an excellent means of saving on fuel and reducing emissions (not everyone, though). The trouble is that hybrid systems add hardware, cost and a lot of complexity, especially for the control systems.

Ford will be launching production of the first EcoBoost V6 engines early next spring for installation into the Lincoln MKS and Ford Flex. The first units will get a 340 hp, 340 lb-ft performance rating and Ford is planning to charge a $700 premium for the new 3.5L turbocharged and direct injected engine. Compared to a similarly powerful V8 engine, the fuel savings from the new V6 are estimated at $339 a year at $3.25/gallon. At current prices the savings will obviously be even higher. In 2010, F
