Lotus will not make an official announcement until sometime later this year. Strongest rumours still seem to center around a Toyota powerplant, the 1.8 l vvti, currently used on the Celica. Lotus isn't saying either way, but they have tested a number of other manufacturers' engines as well. One fellow that I spoke with recently who is quite well-connected with Lotus wasn't saying what the choice was, but his demeanor indicated that the Toyota may not be the choice, after all. So, the intrigue continues....it will be an exciting year as more of the details about the US-bound model emerge !
