BMW offering glitch fix for i3 with range extender

The BMW i3 has received quite a bit of acclaim since its release, with the electric powertrain grabbing a spot on Ward's 10 Best Engines list and the high-tech machine earning the nod as 2015 Green Car of the Year. However, Consumer Reports uncovered a vexing problem with the range-extended version of the hatchback that has plagued it until a recent software update. While CR was driving the range-extended i3 last year, it discovered that when the internal combustion engine was running during low states of charge, hard acceleration could suddenly cut back with no warning to the driver. This was especially problematic when passing. BMW knew about the issue and promised a software update in the spring. That improvement is now available. BMW spokesperson David Buchko tells Autoblog that the software update adds a percent-of-charge indicator to all models of the i3 to let drivers know just how much juice is left. For the range-extended model, it also provides a warning of possible power reduction when the charge reaches two percent. According to Consumer Reports, the revision lets the car anticipate needing more reserve power based on the topography from the navigation system, as well. For any i3 drivers who want the upgrade, they need to visit a dealer for installation, according to Buchko, but it should be come at no cost to owners. Related Video:

Lexus back in luxury sales race after three-year absence

Think the only challengers for the title of best-selling luxury brand hail from der Vaterland? Wrong. Lexus outsold the likes of Mercedes-Benz for the second time in 2014 last month. In fact, the Japanese luxury marque's total sales this year are a mere 12,000 units behind BMW.
Lexus was able to move 26,921 vehicles last month, a year-over-year increase of 21.1 percent, respectively. Mercedes, meanwhile, was just barely beaten, moving 26,617 units in April. The difference, though, is that Lexus has made far bigger year-over-year gains than Mercedes, which recorded a YOY increase of just 4.13 percent.
This is particularly troubling for the Germans, as it marks a return to form for Lexus that we haven't seen since before the March 2011 earthquake and tsunami that decimated Japan. Prior to that natural disaster, Lexus enjoyed nearly a dozen years at the top of the luxury heap.

Recharge Wrap-up: Houston's bus revival, autonomous trucks on the Autobahn

A documentary shows how Houston, Texas significantly improved its outdated bus system. Called High Frequency: Why Houston is Back on the Bus, the short film describes how the city reimagined its bus system to become more efficient, more useful and more popular. Despite some opposition, the change has proven to be effective, with bus ridership up eight percent in three months, and light rail ridership up due to complementary bus routes. See the video above, and read more at CityLab. Automakers sent autonomous semi trucks on the German Autobahn as part of the European Truck Platooning Challenge of 2016. Mercedes-Benz, Volvo and Scania, among other groups, sent platoons of trucks between Stuttgart, Germany, and Rotterdam, Holland. In Mercedes's platoon of three trucks, the lead truck was fitted with lasers and other sensors to guide the convoy down the road. The two following trucks relied on vehicle-to-vehicle communication to trail 50 feet behind the lead, making room for cars to come between them and closing the gaps when able. The close following distance provides fuel economy gains of up to 10 percent in the rearward trucks on account of the reduction in drag. Read more at Hybrid Cars. Renault has reduced NOx emissions in its Euro 6b diesel vehicles in real world driving conditions. By improving its exhaust gas recirculation systems and NOx traps, nitrogen oxide emissions are cut in half on average, under certain driving conditions.
