Driving the Lincoln Aviator and flogging Abarths at Laguna Seca | Autoblog Podcast #593

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by West Coast Editor James Riswick and Associate Editor Joel Stocksdale. To begin, Greg takes a moment to remember the fastest woman on four wheels and former host of Autoblog's "The List," Jessi Combs, who died this week. Then our editors turn their attention to the cars they've been driving, including the Lincoln Aviator, Ford Ranger and Nissan Frontier, as well as Joel's recent stint in the Fiat 500 Abarth and Fiat 124 Spider Abarth, including track time at Laguna Seca. Finally, they turn their attention to a listener in Germany who is looking to replace an aging Volkswagen Eos with a newer convertible in this week's "Spend My Money" segment.

A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.

Recharge Wrap-up: Nissan Leaf top environmental performer, 50,000th Renault Zoe

Renault has produced its 50,000th Zoe electric car. A Frenchwoman named Sylvie took ownership of the milestone vehicle at the Flins plant where it rolled of the line. She says her children helped convince her to buy the all-electric vehicle, which Sylvie intends to use as a daily driver. The Renault Zoe is Europe's best selling EV since its launch in 2013. Renault reports a 98-percent satisfaction rate with the Zoe. Read more in the press release from Renault. Toyota will use a biosynthetic rubber called biohydrin in its engine and drive system hoses beginning in May 2016. Jointly developed by Toyota, biohydrin is a plant-based rubber with a 20-percent reduction in material lifecycle carbon emissions compared to petroleum-based rubber. Toyota plans to use the compound in even more components in the future, including brake and fuel line hoses. Read more from Toyota. So far in 2016, only 27.5 percent of hybrids and EVs are traded in for another electrified vehicle, according to Edmunds. That's down from 38.5 percent in 2015. 33.8 percent of electrified vehicles are traded in for SUVs. Despite the trend of EV and hybrid owners switching back to traditionally powered vehicles, average fuel economy isn't suffering. "This is an economics trend, since today's low cost of gas no longer makes it worth paying the price premium of hybrids and EVs," says Edmunds Director of Industry Analysis Jessica Caldwell. "And there are so many fuel-efficient vehicles on the market today that environmental concerns weigh less than they might have in years past. When you're buying a vehicle that can get over 30 mpg, you can still say you're doing your part to help the environment." Read more from Edmunds. Environmentally, electrified vehicles outperform their conventional combustion counterparts throughout their lifecycle. A study from the Automotive Science Group (ASG) finds that while production of advanced powertrains comes with a greater financial burden, most vehicles make up for it through efficiencies during their use phase. The ASG lists the 2016 Nissan Leaf as its best performer, with 47 percent fewer greenhouse gas emissions than the best-performing conventionally powered car, the Honda Fit. Rounding out the ASG's top five environmental performers are the Ford Focus Electric, Chevrolet Volt, Toyota Prius Two Eco, and Hyundai Sonata Plug-In Hybrid.
