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.

Daimler and Volvo could jointly develop internal combustion engines

BERLIN — Luxury German carmaker Daimler and Volvo, owned by China's Geely, are considering cooperating to cut the costs of developing combustion engines, a magazine reported on Sunday, citing unnamed company sources. The Automobilwoche weekly cited a Volvo manager as saying there were initial talks with Daimler, but no concrete plans, while a company spokesman said it was too early to talk about firm projects, although it was not excluding anybody. A Daimler spokesman said the company's cooperation with Geely, which owns a 10% stake in the German carmaker, was developing in a positive way, but declined to comment further. Global tariffs, accelerated by a trade war between China and the United States, as well as higher investment requirements for electric and autonomous vehicles, are forcing carmakers to seek new ways to cut and share costs. In October, Volvo said it would merge its engine development and manufacturing assets with those of Geely, creating a division to supply in-house brands and also potentially others with next-generation combustion and hybrid engines. Automobilwoche said this new division would start operating by the end of March, which could be a possible starting point for cooperation with Daimler, while a further step could be a partnership to develop electric power trains. Geely and Daimler have said they plan to build the next generation of Smart electric cars in China through a joint venture and the two companies are also cooperating on a premium ride-hailing service in China. Geely bought Volvo Cars in 2010 from Ford, allowing the Swedish brand to operate on an arms-length basis. But in recent years, it has deepened cooperation between the two brands. Volvo already supplies engines to some Geely-branded vehicles, sharing technology through Geely's Lynk brand. Both companies share and develop common vehicle platforms.

Euro-market Volvo C40 Recharge and XC40 Recharge add efficiency, range

Volvo's tweaked the powertrain specs for the C40 Recharge and XC40 Recharge in Europe in both front- and all-wheel-drive trims. (We don't get the FWD versions here, only the AWD models.) First reported by CarsUK as a rumor, Autocar dug into the details after the new models hit some EU configurators. The big change there is that the front-drivers are now rear-drivers, engineers moving the single motor to the rear axle in the name of efficiency. The battery in the single-motor cars stays the same size at 67 kWh, but motor output rises from 228 horsepower to 235 hp. Even better, the C40 Recharge goes from an estimated 270 miles on a charge to 296 miles, the XC40 Recharge goes from an estimated 260 miles on a charge to 286 miles on the WLTP cycle. The AWD Recharge Twin trims get a larger battery, swapping the 78-kWh unit (75 kWh usable) for a 82-kWh unit (78 kWh usable). Their motors put out the same combined 402 hp as before, but do so with a rear bias. Instead of each motor making 201 hp, the front motor makes 161 hp, the rear 241 hp. Their ranges climb even more, the C40 gaining 37 miles of range to go an estimated 315 miles on a charge, the XC40 adding 42 miles to go an estimated 311 miles on the WLTP cycle. Volvo also upped the fast charging capability for the Recharge from 150 kW to 200 kW. The upgrade cuts the charge time from 10% to 80% by 10 minutes, to 27 minutes, matching the time required for the single-motor trims with the smaller battery to refill the same amount. The revised models can be ordered in Europe now but won't go into production until next year, the Recharge versions in May, the single-motor versions in autumn. Prices are up about 10%. It's thought the Polestar 2 will be in line for the same changes. We asked Volvo USA about the revisions coming to the U.S., aand  spokesperson responded, "We will have more details to share on the U.S. offer at a later date."
