...anybody seen any "specs" for the turbo-1.4L engine yet? Has it been used in Europe already?

Hmm, good thought. I get the sense that this engine was designed more with mpg in mind vs the 260 HP sports car setup. So potentially reciprocating components are balanced further towards light weight and efficiency and thus may carry a lower design safety factor. On the other hand being of smaller displacement, the engine will typically be required to operate in a higher loaded duty cycle... so.
Who knows, I'd like to get some more specs too. The wiki entry is still very slim:
"Opel and US-market Chevrolet versions of the Delta II platform compact cars will feature turbocharged version of the 1.4 L engine with of variable valve timing, and optional gasoline direct injection.[1][2] This small turbocharged engine will deliver the performance of much larger naturally-aspirated engines while maintaining fuel efficiency of a small engine. Expected Highway fuel economy is more than 40 mpg.[clarification needed]
* 1.4 L Straight-4 (1364 cc): 72.5 mm (2.85 in) bore, 80.6 mm (3.2 in) stroke, 9.5:1 compression, 140 hp (103 kW) @ 4900 rpm, 200 N·m (150 lb·ft) @ 1850-4900 rpm.
The engine will be used in:
* 2010 Opel Astra
* 2011 Chevrolet Cruze
Oh, heres some more specs right from GM:
