Mitsubishi Mirage, Toyota thinks of beefing up US production, Marchionne on Alfa, Dart and minivans, Ford Atlas concept, Honda Gear concept
Episode #317 of the Autoblog Podcast is here, and this week, Dan Roth, Jeff Ross and Michael Harley bookend the other podcast topics with a pair from the Montreal Auto Show, the Mitsubishi Mirage and Honda Gear concept, and in between we talk about Toyota building all its US-market cars stateside, Hyundai building a Nurburgring test facility, Sergio Marchionne's latest words about Alfa Romeo, Dodge Dart powertrains and the future of Chrysler vans. Some chatter about the Ford Atlas concept finishes up the meat of the 'cast and then we wrap with your questions. For those of you who hung with us live on our UStream channel, thanks for taking the time. Keep reading for our Q&A module for you to scroll through and follow along, too. Thanks for listening!

Volvo specs new 450-hp triple-charged four-cylinder engine

When Volvo lifted the veil on the new XC90 a little over a month ago, it announced that all versions would be powered by one engine design: a new 2.0-liter four-cylinder to be offered in various states of tune. That would range, Volvo said, all the way up to a high-output version with "around 400 horsepower," but while it wouldn't specify exact output, now it has.
The new High Performance Drive-E Powertrain incorporates two parallel turbochargers fed by a third electric turbo-compressor. Instead of feeding the cylinders directly, that third unit spools up the twin turbochargers, working together with a dual fuel pump pressurized to 250 bar.
The result is an output of 450 horsepower - far more than the existing 320-hp version and even more than expected. That also works out to 225 hp/liter, far more than the 177 hp/liter boasted by Mercedes-AMG's high-output turbo four and the 139 hp/liter in the Alfa Romeo 4C. Short of a rotary engine (whose actual displacement is the subject of great debate), you'd have to go up to something like the Koenigsegg One:1 (268 hp/liter) to find a higher specific output than what Volvo's boasting here.

Hyundai Sonata PHEV may be a game (and mind) changer

If you really, really want to consume volts instead of fuel on your way to work, school or shopping, you currently have just three options: pure EV, hydrogen fuel cell, or plug-in hybrid EV. Much as we love them, we all know the disadvantages of BEVs: high prices due to high battery cost (even though subsidized by their makers), limited range and long recharges. Yes, I know: six-figure (giant-battery) Teslas can deliver a couple hundred miles and Supercharge to ~80 percent in 10 minutes. But few of us can afford one of those, Tesla's high-voltage chargers are hardly as plentiful as gas stations, and even 10 minutes is a meaningful chunk out of a busy day. Also, good luck finding a Tesla dealership to fix whatever goes wrong (other than downloadable software updates) when it inevitably does. There still aren't any. Even more expensive, still rare as honest politicians, and much more challenging to refuel are FCEVs. You can lease one from Honda or Hyundai, and maybe soon Toyota, provided you live in Southern California and have ample disposable income. But you'd best limit your driving to within 100 miles or so of the small (but growing) number of hydrogen fueling stations in that state if you don't want to complete your trip on the back of a flatbed. That leaves PHEVs as the only reasonably affordable, practical choice. Yes, you can operate a conventional parallel hybrid in EV mode...for a mile or so at creep-along speeds. But if your mission is getting to work, school or the mall (and maybe back) most days without burning any fuel – while basking in the security of having a range-extender in reserve when you need it – your choices are extended-range EVs. That means the Chevrolet Volt, Cadillac ELR or a BMW i3 with the optional range-extender engine, and plug-in parallel hybrids. Regular readers know that, except for their high prices, I'm partial to EREVs. They are series hybrids whose small, fuel-efficient engines don't even start (except in certain rare, extreme conditions) until their batteries are spent. That means you can drive 30-40 (Volt, ELR) or 70-80 miles (i3) without consuming a drop of fuel. And until now, I've been fairly skeptical of plug-in versions of conventional parallel hybrids. Why?
