Audi reveals new TT spec racer

We've seen the coupe. We've seen the convertible. We're still waiting on word of the next variant, but before it arrives, Audi has revealed the racing version of the new TT.
Set to form the backbone of the inaugural Audi Sport TT Cup, the competition-spec sports coupe is closely based on the production version packs the same 2.0-liter turbo four and six-speed dual-clutch transmission as the road-going TTS, delivering the same 310 horsepower, but with a push-to-pass boost of an extra 30 hp.
It's also got an active differential, and while the full specifications have not yet been revealed, it's clear that Audi has also outfitted the TT racer with more aggressive aero, track-spec rolling stock and a stripped-out cockpit (complete with the Audi PS1 Safety Seat from the R8 LMS Ultra) to get weight down to from 2,700 pounds in stock production form to 2,480.

2014 Audi A7 TDI

If you're a frequent reader of car reviews (my money says you are), you've no doubt come across prose about how a car "checks all the right boxes." It's a common phrase - I'm guilty of using it myself. And I'm about to use it again.
You see, I've just spent a week with the 2014 Audi A7 TDI, shown here against the backdrop of sunny SoCal, even though my stint was spent slopping through this absolutely wonderful winter we've been having in Detroit. If you're one of our podcast listeners, you've already heard me wax poetic about the A7 TDI, and the more I reflect on this diesel darling, the more I firmly believe that this car absolutely, without a doubt, checks all the right boxes.
Well, almost all of them, anyway.

To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.
