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 developing new three-cylinder engine family

Pop the hood on a Volvo of recent vintage and you'll find four-, five-, six- and even eight-cylinder engines. But the Swedish automaker is downsizing its engines over the coming years. The new XC90, set to be revealed later this week, will use a new family of four-cylinder engines (like the one pictured above). But that's not even the end of it as emerging reports speak of a new three-cylinder engine family in the works.
The new 1.5-liter turbocharged three-cylinder engine will, according to reports, help Volvo further cut its carbon emissions in line with constricting regulations in markets like Europe and Australia. There won't be quite as many versions as the four-cylinder range, which will include gasoline and diesel versions in varying states of tune, but the three-pot motor is tipped to be employed in vehicles as large as the S60 and its stablemates. Larger than that, however, and the three-cylinder engine apparently just doesn't have the necessary torque.
Expect the new three-cylinder engine to be introduced sometime later this decade, after the four-cylinder's introduction in 2016. The three-cylinder engine is also set to form the building block of an even more efficient hybrid propulsion system in the future, enabling this new engine family to stay relevant through 2025.

Edmunds ranks the best used cars for 2013

When people ask us what car we would recommend for them, it's usually not easy to answer. To make a useful recommendation we must consider which of the numerous vehicle segments fits their needs best, and then choose one of the many vehicles offered in each segment. For some people, new cars don't meet their expectations of value, because they lose so much of it the moment they are purchased and driven off the dealer lot. For them, there's always the used-car market, where great deals can be found, but cars' histories of reliability and maintenance records - and perhaps that Certified Pre-Owned warranty - become ever-important factors playing into purchase choice.
To help out, Edmunds has done us the favor of assembling a list of the best used vehicles money can buy, covering model years 2006-2011, according to what it considers the most important criteria when shopping for used autos: reliability, safety, value and availability. That means unreliable, unsafe, super-expensive or limited-edition models don't appear on the list, but instead cars from each segment that are more likely to satisfy the general population.
There are some real goodies on the list, including but not limited to vehicles such as the capable Honda Fit, the cultish Honda Accord coupe (which can be had with a 240-horsepower V6 and a six-speed manual transmission some years), and the powerful Chevrolet Corvette. While Edmunds' choice of the Volvo C70 for best used convertible baffled us at first (not that it's a bad car), it redeemed itself by stating that the Mazda MX-5 still is an unofficial top choice if you don't require more than two seats.
