Audi calls R18 E-Tron Quattro its 'most complex race car'

Technically speaking, Audi's R18 E-Tron Quattro is quite technical. The German automaker says the diesel-hybrid is the "most complex race car" it's ever created. And we'll take their word for it. The Audi, which pairs a V6 turbodiesel powering the rear wheels with two electric motors, is all about connectivity, giving the car's crew the opportunity to constantly monitor the vehicle while it's racing. The car sends in a host of data each lap to the crew's computers, and the vehicle's telemetry system constantly keeps tabs on things like hybrid energy levels, cockpit temperature and boost-pressure levels. In all, the amount of data parameters is more than 100 times greater than in 1989, when Audi first tested a race car equipped with automatic data transmission capabilities. Audi first released specs on the updated version of the R18 E-Tron Quattro late last year, trumpeting the vehicle's advantages in competing in the LMP1 class of the 2014 World Endurance Championship (WEC). Audi made the car a little narrower and a little taller and it complies with a new WEC regulation requiring the front end set off by a new wing. Take a look at Audi's most recent press release below. AUDI R18 E-TRON QUATTRO WITH COMPLEX ELECTRONIC ARCHITECTURE • Telemetry connection between race car and pit lane • Permanent acquisition of far more than 1,000 parameters • Various electronic control units interlinked by a multitude of CAN Bus systems Ingolstadt, May 5, 2014 – The Audi R18 e-tron quattro is the most complex race car created in Ingolstadt and Neckarsulm to date. This not only applies to the mechanics. The electronics of the most recent LMP1 race car with the four rings is more sophisticated than ever before. The age of electronic data transmission from the race car on track began for Audi in 1989. At that time, an Audi 90 quattro in the IMSA GTO series radioed eight parameters to the garage where engine speeds and a few pressures and temperatures were plotted on printouts – a tiny step from today's perspective, but one that provided important insights at the time. Today, an Audi R18 e-tron quattro on more than a thousand channels, in cycles that in some cases only amount to milliseconds, generates data of crucial importance to a staff of engineers at Audi Sport. At Le Mans, the engineers constantly monitor their race cars for 24 hours.

Is Audi getting complacent and suffering from brain drain?

The argument is made in a Reuters article: Audi is falling behind other luxury brands, such as Mercedes-Benz and BMW, due to a lack of research-and-development spending and "brain drain," or the migration of top executives and R&D chiefs to other parts of the Volkswagen Group. Reuters notes that Audi's current R&D chief is the third in 16 months.
Audi, which contributed to 40 percent of VW Group's $11.6 billion in profit the first nine months of the year, is delivering cars at a record pace: 1.31 million were delivered from January to October 2013 versus BMW's 1.35 million. Yet Audi, Reuters reports, doesn't have a halo car akin to BMW's new electrified i3 and i8 or an answer to Mercedes' plug-in-hybrid S-Class, and the R&D spending at Audi is less than BMW and Mercedes by a fair margin. It's noted in the article, however, that Audi benefits from other R&D spending within VW Group.
Reuters mentions that BMW "trumpets its new 'i' series" and the new Mercedes CLA and GLA ranges are winning "rave reviews" as part of its argument that Audi's recent lack of technological innovation could hurt future sales. Those cars do pack tons of new technology, some of which are firsts for mainstream production cars. But last time we checked, the i3 could be causing BMW's stock to slide, the CLA isn't receiving the rave reviews that Reuters would have you believe and the GLA hasn't been reviewed yet.

The Audi Q7 doesn't want me to speed and I'm not totally okay with that

I'm a big fan of adaptive cruise control. My commute is 50 miles each way, almost all on freeways here in Michigan. If everyone drove at the same speed there'd be little need for smart cruise, but I live in reality where people camp out in the left lane and practice going from the gas to the brake for no apparent reason. Radar cruise systems let me set my max speed and just worry about steering. But Audi has gone a step further with its adaptive cruise system. And it's a step I'm not sure I'm comfortable with. Audi's system, as featured on the new Q7, has a feature that uses the forward-facing camera to read speed-limit signs, something that's becoming common in Europe and is now making its way here in the continent's luxury cars. That part's fine; it's useful information and gets nicely integrated into Audi's Virtual Cockpit screen and on the head-up display. What the car then does with that info, however, is the issue: If your set cruise speed is higher than the speed on a sign you pass, the car will drop the cruise speed down to the limit. But it's not perfect. On one stretch of highway, the Q7 picked up the speed limit posted on the parallel service road, dropping me down from a little above the limit to 30 mph. It didn't slam on the brakes, but it did confuse me at first and require intervention before the car slowed down to a crawl. This feature isn't ready for primetime. Luckily, it can be turned off or switched to a mode where it gives you a warning that the speed limit has changed (or at least that the car thinks it has) and lets you react before the set cruise speed is changed automatically. When activated, it's a safety issue. A more serious one, in my opinion, than driving a little over the speed limit, especially when it means interrupting the flow of traffic. There's nothing predictable about a car trundling along in the fast lane and then completely letting off the gas. It's not predictable for the driver behind you, and it's not something a driver expects of their own vehicle. Yes, this feature was obviously developed for people driving on the Autobahn, where speeds can drop down from unlimited to a slow crawl pretty quickly when entering a construction zone or approaching a built-up area. German roads also have more consistent signage, so the false-positive scenario I experienced might not have come up there.
