Audi launches traffic light timing system in Las Vegas

Audi announced today that its new Traffic Light Information (TLI) system will go online in Las Vegas this month, making it the first city to activate a vehicle-to-infrastructure (V2I) system on public roads. The system transmits information from traffic lights to servers operated by Audi partner Traffic Technology Services and onto compatible Audis over a 4G LTE connection. This will allow drivers to see how long it will take the red light ahead to change to green. The feature is available on Audi A4, A4 Allroad, and Q7 models built after June 1, 2016, and requires a subscription to Audi's streaming service. Audi points out that setting up a V2I infrastructure opens up the possibility to provide navigation directions that take traffic lights into account. Cars could even coach drivers how fast to go to hit more green lights. In addition, this information could allow engine start-stop systems to shut off sooner when approaching red lights and start up immediately when the light turns green. Information could also flow back to municipalities, giving them a more accurate picture of traffic flow. Washington will soon join Las Vegas in supporting Audi's V2I technology. They're the only two cities confirmed so far, though Audi says it's working to get more on board. Related Video:

China probing German automakers over spare parts

The Chinese market has proven to be a boon to German luxury automakers. However, the way that the companies have allegedly been controlling their supply of spare parts has begun to draw the ire of the nation's government. According to insiders speaking to Bloomberg, officials from the country's economic planning organization have opened a probe into Audi, BMW, Mercedes-Benz and some Japanese carmakers over claimed price inflation and limiting supply.
Specifically, the investigation centers around two aspects of how the companies do business, according to Bloomberg. Investigators want to know whether the original equipment component makers are able to sell spare parts only to automaker-authorized dealers or if they are also available to independent shops. There is also the issue of whether the price markup on replacement pieces is too high. The tight controls could be partially explained by China's reputation for producing counterfeit parts.
Evidently, the investigators haven't checked parts prices at car dealers elsewhere in the world. At least in the US, paying more at the dealer for factory components just goes along with owning a vehicle. If evidence of price fixing is found, the companies could face fines the equivalent of millions of dollars, according to Bloomberg.

2021 BMW M3 and M4 vs all the high-powered sport sedans and coupes

Should you have a found a way to get past that schnoz, you've probably digested some of the basic specs for the all-new 2021 BMW M3 sedan and M4 coupe specs. They're plenty impressive. There's also, basically, two sets of them thanks to the regular and Competition versions that differ in engine output and transmission type.  But how do they compare to other ultra sport sedans and coupes? Well, we were wondering that too, so we fired up the Autoblog Comparison Spreadsheet Generator 5000 (aka me chained to my computer in a dark basement).  Sadly, there are surprisingly few competitors for the 2021 BMW M3. Rival sedans include the Mercedes-AMG C 63 and the Alfa Romeo Giulia Quadrifoglio, along with the Audi RS 5 Sportback sedan/coupe/hatchback thing. There's no more Lexus IS F, the Cadillac CT4 Blackwing has yet to arrive and Jaguar doesn't offer a spicy XE R.  Happily, there are more coupe rivals for the 2021 BMW M4, including the two-door versions of the AMG and Audi as well as the Lexus RC F. I also included the Ford Shelby GT350 and Chevrolet Camaro SS 1LE. On paper, they align incredibly well. On the street and on a track, I can personally attest that these Americans are fully capable of keeping up and/or bettering the fancy-pants luxury brands (and let's not forget there are even more powerful, hardcore versions available). If they don't align in terms of price or prestige, whatever. OK, let's get to the spreadsheet. Let's start with the coupes and note that I didn't bother listing the dimensions for the M4 Competition and C 63 S as they are identical to their "lesser" siblings.  I won't bother burning words explaining what you can see on the chart. Instead, I'll point out a few things that stood out to me. First, BMW M comes awfully close to matching the output of AMG's twin-turbo V8 despite having two fewer cylinders. Similarly, Audi manages to better the 0-60 time of the M4 Competition and tie the C 63 S despite being WAY down on power. It's not like it weighs less. Magic? Second, and speaking of 0-60 times, remember the importance that transmission and drivetrain make with them. It's not just horsepower and torque. An automatic will be quicker and easier to launch than a manual, while all-wheel drive provides more instantaneous and beneficial grip.
