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 recalls handful of vehicles for risk of false alarm

Volvo’s latest tech updates have made its vehicles easier to live with and safer, but as with any significant change, there are bumps in the road. The automaker recently recalled a handful of 2023 model-year vehicles for an issue that could cause false warning lights in the gauge cluster. The recall covers the Volvo S60, V60, XC60, XC90, and C40, with build dates that range from late 2022 to March 2023, depending on the model. An issue with the Telematics Connectivity Antenna Module (TCAM) could falsely trigger an error related to communications between the infotainment head unit. The driver receives an “e-call service required” message in the gauge cluster, but the system will continue to operate normally with the error. Though thereÂ’s no real problem or immediate danger when this happens, the false message can obscure a legitimate problem. The e-call feature is part of VolvoÂ’s onboard safety equipment that communicates information after a crash or other incident, so itÂ’s important to know when itÂ’s functioning correctly. There has been only one report of this problem in the U.S., and the recall only involves 329 vehicles. Thankfully for the affected owners, the fix is a simple software update to change the TCAMÂ’s logic. The update is ready to go, and dealers have been notified. The NHTSA said owners would be notified by mail in mid-May, but if your Volvo is acting up, itÂ’s a good idea to call the dealer when you notice. This is the third recall for several 2023 Volvos since last October. All three have involved software issues. The first involves a loss of drive power due to an error in the software that prevented the combustion engine from starting when the vehiclesÂ’ plug-in hybrid batteries were depleted. The second happened in January and related to diagnostic errors in the braking control module that could cause the electronic stability control, antilock brakes, and traction control to malfunction.

Automakers want to stop the EPA's fuel economy rules change, and why that's a shortsighted move

With a Trump Administration looming, the EPA moved quickly after the election to propose finalizing future fuel economy rules last week. The auto industry doesn't like that (surprise), and has started making moves to stop the EPA. Ford CEO Mark Fields said he wanted to lobby Trump to lower the standards, and now the Auto Alliance, a manufacturer group, is saying it will join the fight against cleaner cars. The Alliance represents 12 automakers: BMW, Fiat Chrysler, Ford, GM, Jaguar Land Rover, Mazda, Mercedes-Benz, Mitsubishi, Porsche, Toyota, VW, and Volvo. Gloria Bergquist, a spokesperson for the Alliance, told Automotive News that the "EPA's sudden and controversial move to propose auto regulations eight months early - even after Congress warned agencies about taking such steps while political appointees were packing their bags - calls out for congressional action to pause this rulemaking until a thoughtful policy review can occur." The EPA was going to consider public comments through April 2017, but then said it would move the deadline to the end of December. That means that it can finalize the rules before President Obama leaves office. The director of public affairs for the Consumer Federation of America, Jack Gillis, said on a conference call with reporters last week when the EPA originally announced its decision that it is unlikely that President Trump will be able to roll back these changes. Gillis also said on the same call that any attempt by the automakers to prevent these changes would be history repeating itself. "These are the same companies that fought airbags, and now promoting the fact that every car has multiple airbags," he said. "These are the same companies that fought the crash-test program, and now are promoting the crash-test ratings published by the government. So, it's clear that they're misperceiving the needs of the American consumer." There are more reasons the Allliance's pushback is flawed. Carol Lee Rawn, the transportation program director for Ceres, said on that call that the automotive industry is a global one, and many automakers are moving to global platforms to help them meet strict fuel economy rules around the world.
