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.

China's Geely buying majority stake in Lotus

Geely, the Hong Kong car company that owns Volvo, is acquiring control of British car company Lotus. Geely is purchasing a 51-percent stake in Lotus from struggling Malaysian car company Proton, and a 49.9 percent stake in Proton itself. Etika Automotive will gain the other 49 percent of Lotus. France's PSA Group and Japan's Suzuki had apparently also been interested in acquiring Proton. Geely says it plans to revive both Proton and Lotus. "The agreement lays the foundation for a wider framework for both Geely Holding, Proton and Lotus to explore joint synergies in areas such as research and development, manufacturing and market presence," Geely said in a news release. Those joint synergies will be highlighted by the lightweight chassis technology Lotus is known for, which could help Geely improve fuel efficiency. Geely CFO Daniel Donghui Li said the company aims to "unleash the full potential of Lotus Cars" by expanding and accelerating new products and technologies. Proton was nationally held but was privatized in 2007 to Malaysian conglomerate DRB-Hicom, which is owned by tycoon Syed Mokhtar Al-Bukhary. It was supposed to be the flagship for Malaysia's economic development.Though it owns two factories, Proton mainly rebadges foreign-made cars and sells them in Malaysia. What it has, what Geely presumably wants, is a distribution network in Southeast Asia to pit Chinese cars against Japanese automotive dominance in the region. Retaining a 50.1-percent stake in Proton is seen as a face-saving move. "Proton will always remain a national car and a source of pride, as Proton will still have a majority hold of 50.1 percent," Malaysian finance official Johari Abdul Ghani said. "Our very own much-loved brand now has a real chance in making a comeback, a huge one I hope." Related Video:

Volvo: Tesla's Autopilot is just a 'wannabe'

Using the words "unsupervised wannabe" in an interview with The Verge, Volvo's Trent Victor says the Tesla Autopilot is "giving the impression it's doing more than it is." According to Victor, Tesla's self-driving tech is merely appearing to be autonomous because, with the Tesla system, the driver has to be fully alert all the time, ready to regain control. Tesla says its system is Level 2 autonomous, although some experts regard it as Level 3, which means it takes over safety-critical functions from the driver. Volvo says it pays more attention to actual crash avoidance, and that its Drive Me system is Level 4 autonomous, meaning that in the event of a hazardous situation the vehicle will handle the appropriate procedures and bring itself to a halt in a safe fashion. There will be no need for the driver to take action, which is important in case the driver has been incapacitated while the Drive Me autopilot has been controlling the car. Another thing with the Volvo setup is that it monitors the road in case of a conflict situation, or someone suddenly appearing in front of the car, be it a pedestrian or a runaway child. Tesla has never said that its Autopilot is anything other than a beta version under trial usage. It costs $2,500 when you purchase your Model 2 or X, or $3,000 as a add-on once you've taken delivery. The company also just announced that it would offer Autopilot for free as part of a one-month trial. Tesla declined to comment on Volvo's comment.
