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.

Volvo Concept Recharge previews the future of Volvo design and technology

Volvo has announced a whole slew of information about where the company is headed, from battery technology to advanced driver aids. And it was all capped by the concept car you see above, the Volvo Concept Recharge. It all shows that Volvo's future is stylish, electrified and featuring the latest in safety technology. So, in a way, pretty much exactly what you'd hope and expect. Volvo didn't say much about the specifications of the Concept Recharge, but its design will clearly influence future Volvo models, including the company's upcoming flagship electric SUV that will be revealed next year. The front ditches even faux grilles for a sculpted fascia. The shape does echo some of the look of a grille, particularly with the Volvo slash and badge in the middle. The "Thor's Hammer" headlights remain, and in the case of the concept, they have wild running lights that slide up and out of the way inside the housing to make way for the actual projector headlights at night time. The whole shape of the car is based around the electric powertrain. It has a low floor and glass roof that means the whole body can be made lower and sleeker without compromising space. The wheels are pushed to the far edges, too. At the back, the car has slim vertical taillights, continuing a Volvo design tradition. On the roof, there is a lidar sensor placed at the top of the windshield. This is a significant piece of Volvo's future, as its next generation of vehicles, starting with that aforementioned SUV, will all come with one of these sensors as standard. It will be used in combination with cameras, radar, real-time data, machine learning and mapping data to provide advanced driver aids, including what Volvo describes as "unsupervised autonomous" driving in specific circumstances. Basically, it will be SAE Level 3 autonomy, a step beyond the hands-free, but still supervised Level 2 systems such as GM's Super Cruise. It will only be available on specific roads in specific circumstances, and so it won't be able to handle the entire driving task from driveway to driveway. The company expects to offer this level of autonomy on highways first, and it will only be in specific areas to begin. It didn't give an exact timeline for the roll-out and it will be a more gradual increase over time, rather than everything being launched all at once. The company also emphasized that it will only begin launching the features when they're well and truly ready.

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?
