VW and Volvo both have new "twincharged" engines. A supercharger for low-end torque (eliminates turbo lag, even from a small turbo, entirely) and turbocharger for top-end HP. Think it's a great concept, although expensive.
The CTD, though, has a variable geometry turbo to allow it to create boost at both low and high RPM...not a simple one-sized turbocharger with a wastegate like the 1.4T engines use.
