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.

2021 Ford Mustang Mach-E, Volvo XC40 Recharge score high in IIHS tests

New electric cars continue their streak of impressive crash test results. The two latest to go through Insurance Institute for Highway Safety testing are the 2021 Ford Mustang Mach-E and the 2021 Volvo XC40 Recharge. The former earned a Top Safety Pick award, and the latter picked up the Top Safety Pick+ commendation. Both vehicles got the top "Good" rating in every crash test, as well as the "Superior" rating for vehicle-to-vehicle collision prevention. They deviate when it comes to headlights and vehicle-to-pedestrian collision prevention. Because the Volvo has headlights rated "Good" on all trims, it got that extra "+" on its Top Safety Pick award. The Ford also has high-rated headlights available, but the standard units got the second lowest rating of "Marginal." As for the vehicle-to-pedestrian collision prevention, the Volvo received the second-highest "Advanced" rating, while the Ford was rated "Superior." Among the electric cars IIHS has tested, the Ford and Volvo continue a streak of high scores. The organization has evaluated the Audi E-Tron in both its body styles, as well as the Tesla Model 3, both of which get the Top Safety Pick+ rating. As a result of the XC40 Recharge's test score, Volvo pointed out that it is the only automaker whose entire lineup has received a Top Safety Pick+ rating.

Daimler and Geely collaborate to develop 'a highly efficient modular engine'

BERLIN — German car maker Daimler said on Tuesday it will cooperate with China's Geely to build next-generation combustion engines for use in hybrid vehicles. Efforts to share development costs come as the growth potential for combustion engines faces the twin threat of the COVID-19 crisis and stricter fuel-efficiency and emission rules. "The companies plan to develop a highly efficient modular engine," a spokesman for Daimler said, adding that it would be used in hybrid drivetrains and manufactured in Europe and China. Geely declined to comment. The modular engine will be used in cars under different marques at Geely and Daimler, a person familiar with the matter said on condition of anonymity as the companies are still in the early stages of developing the engine. News of the alliance was a surprise to Daimler's works council at its factory in Untertuerkheim, which specializes in electric and gasoline powertrain assembly. "We are speechless. There was not even a discussion about potential alternative manufacturing locations," said Michael Haeberle, the works council chief for Untertuerkheim. "We have the ability to build four-cylinder engines in Untertuerkheim, but there were no talks about it." Daimler said German factories will be retooled gradually to add electric drivetrains production. Most of the next-generation combustion engines will be made in China, business daily Handelsblatt reported. The alliance with Geely, which owns a 9.69% stake in Stuttgart-based Daimler, means that parts of Daimler's existing partnership with Renault could be pared back. A Renault source told Reuters that the Daimler-Geely project does not mean an end of cooperation between Daimler and Renault. Citing Daimler sources, Handelsblatt said the Daimler-Geely pact would save the German carmaker a "triple-digit million sum" — implying an amount above 100 million euros ($119 million) and less than 1 billion euros.
