Lamborghini makes Aventador more fuel efficient for 2013

I can that imagine someone at Lamborghini thinks that the Aventador's 700-horsepower split between all four wheels is probably enough power for one car. (And no, I don't agree with that person.) I assume this because rather than getting a nominal power bump for this model year's update, the 2013 Lamborghini Aventador LP700-4 gets a mile per gallon bump thanks to the addition of cylinder deactivation and idle stop-start technologies that allow the V-12 engine to instantaneously and momentarily make less power in the pursuit of using less fuel.

The Cylinder Deactivation System (CDS) works like this: … Read more

Expect stop-start's big start to arrive in 2010

Forecasters see 2010 as the big year for Europe's manufacturers of stop-start systems, which turn the engine off when a vehicle stops and restarts it when the driver's foot leaves the brake.

An estimated 2.8 million vehicles with stop-start will be made globally that year. About 2.5 million of those vehicles will be made in Europe and the rest in Asia, according to consultancy IHS Global Insight. That's up dramatically from last year, when about 54,000 stop-stop-equipped vehicles were made, an estimated 53,350 in Europe.

Stop-start maker Valeo SA is looking forward to the surge because it does not make a profit on the system at current volumes. "Today we manufacture 1,000 a month, so it doesn't make sense. But we knew that," Valeo CEO Thierry Morin told Automotive News Europe earlier this year. "It will be a profitable business by 2011, when we have the volumes, in particular from PSA."

The French supplier has a contract with PSA/Peugeot-Citroen to equip more than 1 million vehicles with a stop-start system by 2011. Valeo says the contract is worth 700 million euros, or $897.4 million at current exchange rates. Valeo now supplies stop-start for Citroen, Mercedes, and Smart vehicles.… Read more

Travolution enables traffic lights to talk to cars

Waiting at traffic lights is one of the primary reasons why city mpg is so much lower than highway mpg. Automakers have attempted to address this issue with start-stop technology, but what if you could eliminate the stop altogether? The experimental "Travolution" system, developed with Audi support by traffic management experts in the brand's German hometown of Ingolstadt, aims to do just that and make long traffic light waits a thing of the past.

The system consists of a network of 46 "intelligent" traffic lights (with 50 more light installations planned) installed in the center … Read more
