yep, alfas use variable timing only on the intake cam. and it was actually Alfa Romeo who invented the variable valve timing concept, i found this on an amercian site:
Performance gradually increased from its all-time low of 1981. Alfa kept refining and tuning the engine as much as possible to get power, economy, and emissions control. To this end, in 1980 Alfa incorporated variable valve timing (or VVT). The system is essentially an electromechanical piston on the intake camshaft. Developed in the 1970s by Ing Giampaolo Garcea for Alfa, it was termed "variatore de fase" by the Italian engineers. This was promptly renamed "the phaser" by the Americans involved with the team, and the name stuck.
At first only used as an emissions control device, later versions allowed improved cam timing, giving better performance at high RPM but allowing controlled emissions at idle. I believe it was the only production car available in the US (perhaps anywhere) with such an advanced system until well into the ‘90s. FIAT has rediscovered this device and now fits it to several of its own engine designs. (special thanks to BD for information on the VVT system)
now, honda, toyota, bmw, merc, porsche, ferrari and most other manufacturers use this technology as well.
honda, ferrari, etc have changed the system to an even better one. alfa still use the very basic and original system, that is, variable TIMING on the INTAKE cam. but honda for example, use variable timing AND variable valve LIFT on both the intake and exhaust cams. this is one reason why the 2.0 I-VTEC engine pumps out 240bhp.
as others said, hondas really need to be revved. in low revs they're just normal (slow) cars IMO
