Piezo injection technology breaks into top engine list
Siemens VDO has announced that for the first time an engine equipped with piezo direct injection gasoline (DIG) technology has featured in Ward's 10 Best Engine List of 2007. The 300 hp / 224 kW BMW 335i Twin Turbo 3-liter engine, which features Siemens VDO DIG technology, was unveiled at the Geneva Auto Show last year. The piezo technology, in conjunction with advanced engine management systems, is credited for delivering higher torque and improved vehicle fuel economy. Direct injection fuel delivery, which is widely used in diesel engines, injects gasoline directly into the engine's combustion chamber, enabling the vehicle to start with less fuel, while simultaneously improving vehicle drivibility and emissions.

The Toyota's 3.5 V6 that's in IS350 is also on the 10 best list, and it's a direct injection engine.
The BMW engine isn't even direct injected in the US market...

Yes the N54 IS direct injected in the US. No port injectors and located adjacent to the spark plug.
Toyota is dual injected, port and direct.
