Driving the Honda Ridgeline and marveling at Tesla | Autoblog Podcast #638

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Consumer Editor Jeremy Korzeniewski and Associate Editor Byron Hurd. They start off talking about why more people should buy the Honda Ridgeline, because it's a pretty darned good truck. Next, Byron talks about some Hyundais. He shares his experiences with the 2020 Sonata Hybrid and talks briefly about the prototype 2021 Elantra currently occupying his driveway. Up next, Jeremy shares his feelings about the BMW X1 crossover he spent some time with, prompting the gang to mull over the notion of BMW's modern interpretation of "Ultimate Driving Machine." After that, Byron talks about towing his 1990 Mazda Miata with the 2020 Infiniti QX80, and then they wrap up with some discussion of the mystery surrounding the Ford Maverick and some comments on the current state of Tesla.

Infiniti's variable compression engine in the 2019 QX50 is the first of its kind

The world's first variable compression ratio engine is here, in a production car. That car is the 2019 Infiniti QX50, debuting this week at the Los Angeles Auto Show. The midsize crossover has seen a refresh that has brought it an all-new platform together with new driver assist features, but it's the engine that's the centerpiece here. Nearly everything is continuously variable under the hood of the QX50 – not only the new shift-by-wire XTRONIC CVT. The new VC-Turbo gasoline engine is able to change its compression ratio from 8:1 to 14:1, or anything in between depending of the driving situation; whether there is need for top-end power or turbodiesel-like torque from low revs, or optimized fuel economy. The pistons' reach is continuously adjusted by an electric "Harmonic Drive" motor, which controls a multi-link system, affecting the top-dead-center of the pistons and changing the compression. The engine can also switch between efficiency-maximizing Atkinson cycle and regular combustion cycle, on the go – and there's both multipoint injection and gasoline direct injection employed. The result is 268 horsepower at 5,600 rpm and 280 pound-feet of torque at 4,400 rpm; good figures for a 2.0-liter four-cylinder gasoline engine with a single-scroll turbocharger. Infiniti says that the FWD version's fuel economy of 27 miles per gallon combined is 35-percent better than the previous-generation V6 engine; in AWD guise, it reaches 26 mpg, which is a 30-percent improvement. The new engine is pretty much all-aluminum, but the vaguely magical-sounding "transformative multi-link components" behind the variable compression system are made from high-carbon steel alloy. The engine's multi-link system also enables it to do away with any balancing shafts, and Infiniti compares its smoothness to a V6 rather than a regular four-cylinder. In addition to the aforementioned tech, the VC-Turbo engine has the world's first active engine mount vibration damping system to smoothen its operation even further. Related Video:

Infiniti Emerg-E Concept

The Infiniti Emerg-E is a two-place hybrid gasoline-electric concept that made its world debut at the 2012 Geneva Motor Show. While its sleek shape and stunning styling dropped jaws, those on the green side of things immediately recognized it as a reskinned and updated Lotus 414E - itself a concept based on the Evora that debuted at the same show only two years earlier. Yet there is little wrong with a reworked, Infiniti-badged Lotus boasting 402 horsepower and 738 pound-feet of torque, especially when it features a lightweight, all-aluminum bonded chassis beneath an attractive carbon fiber skin penned by the automaker's Southern California design team.
The hybrid powertrain is all contained aft of the cockpit. Primary propulsion is accomplished with two electric motors, one on each rear wheel, both featuring its own single-speed transmission (this design eliminates the need for a differential and provides electronic torque vectoring control). Energy for the electric motors is stored in a 15-kWh lithium-ion battery placed behind the seats, which is chemically different from the lithium-polymer pack Lotus used in its 414E. Auxiliary propulsion comes from a Lotus-designed, all-aluminum, 1.2-liter three-cylinder gasoline engine, rated at 50 horsepower, that serves as a range-extender after the 30-mile life of the battery pack is extinguished. Teamed with an 8.1-gallon fuel tank, the combo allows the Emerg-E to cruise about 300 miles without stopping.
Offered the chance to take the Emerg-E for a quick loop around an autocross course in Southern California, I jumped at the opportunity.
