2022 Acura MDX and a trio of lovely sedans | Autoblog Podcast #662

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Road Test Editor Zac Palmer. This week, they talk about the cars they've been driving, including the 2021 Volkswagen Arteon, 2021 Kia K5 GT, 2022 Acura MDX and long-term 2021 Acura TLX. In this week's news, they talk about the possibility of a Nissan Xterra return and break down what's going on over at Lotus — the British sports car company is axing its current lineup and replacing the Elise, Exige and Evora with a new car called the Type 131.

VW Golf TDI circles US on less than $300 of diesel

$294.98. That's how much it cost the Volkswagen team to drive across all 48 contiguous states in the union. Which is pretty impressive, but it's only part of the story. In an effort to demonstrate just how economical a conventional diesel engine can be, VW sent a team out from its US headquarters in Herndon, VA, in a Golf TDI. Their mission was to visit all the Lower 48 on as little fuel as possible. Over the course of 16 days, they traveled 8,233.5 miles, burned through 101.43 gallons of fuel, and marked a frankly astonishing average of 81.17 miles per gallon. As a result, the team – made up of hypermiling automotive journalist Wayne Gerdes and electronics engineer Bob Winger – picked up a new Guinness World Record for the lowest fuel consumption achieved in a non-hybrid car across the 48 contiguous states. The previous record, it's worth noting, had also been set by VW and Gerdes, who piloted a 2013 Passat TDI at just a hair under 80 mpg. But here's the kicker: in raising the diesel economy bar even higher, the team also beat the record for the same achievement in a hybrid vehicle by over six mpg. So the next time someone tries to tell you a hybrid is more efficient than a diesel (at least on the highway), you can point them towards this record.

Traveling 8,233.5 miles around America in 16 days on $294.98 of Shell® Diesel fuel, the Golf beat the previous mark of 77.99 mpg by more than 3 mpg, and also beat the hybrid vehicle record of 74.34 mpg by more than 6 mpg. "Covering 8,233.5 miles on just 101.43 gallons of Clean Diesel fuel is a remarkable accomplishment, and solid proof of the efficiency and fuel economy of Volkswagen's TDI® Clean Diesel vehicles," said Michael Horn, President and CEO, Volkswagen Group of America, Inc.

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.
