New Mercedes SL 400 replaces SL 350

The new Mercedes SL 400 (pictured) replaces the old SL 350 It’s a little over two years since the latest Mercedes SL arrived, and Mercedes has now decided to add a little zest to sales by dropping the old SL 350 and replacing it with a new Mercedes SL 400. The new SL 400 gets its power from the new E400 which means a twin-turbo 3.0 litre V6 with 328bhp and 354 lb/ft of torque – 26bhp and 81 lb/ft more than the old SL 350 – enough to let the SL 400 scoot to 62 mph in 5.2 seconds – 0.7s better than the 350 -= and on to a limited top speed of 155 mph. The new SL 400 has to make do with Mercedes tried and tested 7-speed auto – despite a new 9-speed now being available in Mercedes’ arsenal – which gives the SL 400 official economy of 38.6 mpg and emissions of 172g/km – not that you’ll come close in the real world.

Watch: 2014 Ram 1500 EcoDiesel video walkaround

Mike Cairns, chief engineer for Ram, says that people just can't help but pester him with the same damned question: “Why don't you put a diesel engine in a 1500?” Thanksgivings were, we imagine, brutal. The coming 2014 Ram 1500 EcoDiesel ought to steer family dinners back to less abrasive topics, like partisan politics. Get an up-close look at the truck in this video walkaround hosted by none other than Cairns himself.

Tuner MTM debuts 722 hp Audi RS6 Avant

It seems a minor horsepower war has just erupted over in Germany, and the title at stake in this conflict is which tuning house can build the most powerful Audi RS6 Avant. Not that long ago ABT Sportsline unveiled a 700 hp Audi RS6 Avant, an absolutely rabid grocery-getter that can make the sprint to 60 in just 3.4 seconds. ABT's RS6 Avant packs 25 percent more power than the stock version of the RS6 Avant, which made an already hair-raising 560 hp.
