The Mazda CX-9's new turbocharged four-cylinder could see duty in the brand's other products, which means it's more of a product planning decision than an engineering one.
There's some concern among a portion of drivers that the move from big displacement, naturally aspirated performance engines towards smaller, turbocharged units is somehow diluting the experience behind the wheel.

Turbo compounding is the process of using a turbo run off exhaust gasses to provide additional power to the crankshaft via gearing or a hydrodynamic coupling, or to power a generator that distributes energy via a power electronics module. The technology isn't new - the aerospace industry introduced the concept in the 1940s - but an article in Car and Driver says it could be "the next big thing in energy recovery" for automotive engines.
Forced induction has definitely hit trend status when it comes to performance cars. Whether it's the supercharged Hellcat V8 in the Dodge Challenger SRT, the latest twin-turbocharged M3/M4 or even the entry-level speed of the Ford Fiesta ST, if you want the fastest car in any given segment, in all likelihood it has a turbo or supercharger. Even Ferrari hasn't avoided the bandwagon with the latest iteration of the California that replaces the original 4.3-liter V8 with a 3.9-liter turbo V8 offeri

Consumer Reports has taken aim at at small-displacement, forced-induction engines, saying the powerplants don't manage to deliver on automaker fuel economy claims. Manufacturers have long held that smaller, turbocharged engines pack all power of their larger displacement cousins with significantly better fuel economy, but the research organization says that despite scoring high EPA economy numbers, the engines are no better than conventional drivetrains in both categories.

It's an increasingly turbocharged world out there. At least according to Honeywell, one of the major automotive suppliers for turbochargers around the world. And it's easy to understand why – as fuel mileage requirements are increasing, engine sizes are decreasing. To continue offering the power levels to which modern automotive buyers have come to expect, forced induction offers a ready solution.
Like almost every other automaker these days, Ford is having a tough time in Europe right now, and here in the States, its per-share stock price is lagging, but that isn't stopping the automaker from exceeding some of its goals. The Detroit Free Press reports that sales of the company's EcoBoost turbocharged and direct-injected engines are going beyond expectations.
