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.

Junkyard Gem: 1997 Volvo V90

Volvo's "Brick Era" of squared-off rear-wheel-drive machines lasted from the debut of the 144 in 1966 all the way through the 900 Series cars of the 1990s, with the wildly successful 240 being the most iconic of the breed on our shores. The final chapter of the Swedish Brick saga came in the 1997 and 1998 model years, when the 960 sedan and wagon were rebadged as the S90 and V90, respectively. Here's one of those cars, a refrigerator-colored (and refrigerator-shaped) V90 wagon that got forcibly retired after a crash in Northern California. Volvo revived the V90 name in 2016, and you can buy a new V90 right now if you so choose. Today's Junkyard Gem, however, is the culmination of four decades of improvement to the original 140 design (itself based on much of the Amazon's chassis features and sharing plenty of components with the 1940s-era PV Series cars), while the current V90 comes straight out of the 21st century. I've been going out of my way to document just about every discarded 140 and 240 wagon I find, with some 740s and 940s mixed in. Many Volvo longroof owners still maintain a fanatical devotion to the rear-wheel-drive bricks, and I've found some of these cars in junkyards with impressively high final odometer readings. The fuel-efficiency and interior-space limitations of the old-timey brick design kept 960 sales lower than those of their predecessors, though, and I haven't met any 960 owners who share the level of devotion that 145 and 245 owners lavish on their cars. This car just squeaked past 150,000 miles during its 24 years on the road. The body and interior look to have been in very nice condition, showing that meticulous owners took good care of this car throughout its life, but then it got T-boned on the right side. This sort of damage isn't worth fixing on a quarter-century-old European wagon, and so here it sits. This engine compartment looks very similar to that of the old 240, though this modern 3.0-liter, DOHC straight-six and its 181 horses runs counter to the super-sensible spirit of most of those 1970s Goteborg bricks. The 960 was far more plush than its ancestors, and priced accordingly. In 1997, this car's list price started at $35,850 (about $60,660 in 2021 dollars). By comparison, a new 1975 245 wagon had an MSRP of $5,795 (about $29,940 today).

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.
