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 working to allow groceries delivered to your car, even when you aren't there

Volvo cites research showing that 60 percent of online shoppers had problems with their deliveries in 2013, and that missed first deliveries cost the industry roughly one billion euros ($1.37B US) in re-delivery costs, as impetus for its "Roam Delivery Service" that delivers packages to your car. The service uses Volvo On Call and Sensus Connect car-connectivity and telematics apps already installed in vehicles, and a digital key with a timed window of operation.
The car owner is notified if delivery to or pickup from the car would be the best option, which they then have the option to approve or decline. If approved, the position of the vehicle is sent to the delivery driver, as well as a digital key that can open the car. Once the delivery has been made, the owner is notified and the digital key is erased, leaving only a time stamp to record when the car was opened and then locked.
The technology will be shown to the public at the Mobile World Congress later this month. There's a video and a press release below with more on the details.

Volvo promises new direct-injected diesels, 8-speed auto

As a part of eliminating its dependence on Ford platforms and powertrains, Volvo has previously announced information about its Volvo Engine Architecture (VEA) and Scalable Platform Architecture (SPA), but now we're finally getting some details about what will power some of the Swedish automaker's next-generation products.
The biggest key to VEA on the diesel engines is a new technology Volvo calls i-ART. This system uses unique injectors at each cylinder capable of monitoring fuel pressure and adjusting accordingly to maximize fuel economy and performance and reduce emissions. Looking ahead, Volvo says its four-cylinder engines will be able to offer the power of a six-cylinder and eventually, mixed with some sort of electrification, will be able to rival the performance of a V8 and "turn V8s into dinosaurs."
More details about the new diesel injection technology is posted in the press release below.
