MTM turns up the wick on the 2010 Audi S4

The tuners at MTM have begun tweaking the all-new 2010 Audi S4 (B8) in Europe, and as expected, Audi's new supercharged 333-hp 3.0-liter V6 is rife with potential. With only a revised ECU and an underdrive pulley – no intake or exhaust mods – MTM was able to coax 430 crank horsepower out of the blown six – 97 hp more than stock.

The kit, which retails for 2,491 euros (around $3,500 USD), brings torque output up to 380 lb-ft and, according to MTM, drops the 0-60 mph time from 5.2 to 4.6 seconds. Clearly, good things are on the way for the BMW M3 fighter, and we expect more to follow when the new darling of the Euro-tuning scene arrives in the States later this year.

2010 Citroen C3 is here

The Citroen C3 is old enough in car years that it's getting a re-do before it undergoes a mid-life crisis. The new version is certainly a more mature design, receding hairline and all. Citroen has come up with its own euphemism for it, coining the phrase "Zenith Windscreen" to describe a large windshield that extends further up into the roof than normal to create a panoramic feel to the interior.

The new C3 is a smoother looking supermini than before, with slicker styling keeping it modern and slipping through the air with a Cd of .30. Inside the redone sheetmetal, the interior gets classed up and quieted down. Most notably, there's an integrated air freshener, presumably useful when you're using all 10.5 cubic feet of boot space to haul big dogs or foie gras party platters.

An HDi (Citroenese for "diesel") engine keeps CO2 emissions low, and new powerplants are in the pipeline for 2011. The new engines will use stop/start, the diesel versions of which will drop carbon dioxide emissions further, while gasoline-fueled C3s will also dip below the 100g/km of CO2 emissions level with a new three-cylinder engine. The C3's new duds don't come with the typical generational increase in weight, and the Chevron-emblazoned C-class car will motor onto the small car battlefield ready to earn more accolades with its latest generation.
