I dont think a stock 05 could reach 60 in 4.3sec unless dropped from a plane.
Agreed. I've owned an '06 Elise NA (Naturally Aspirated), an '08 Elise NA that was converted to an SC (Supercharged), and an '11 Elise SC. There is no way that an NA Elise is as quick to 60 in stock form than a stock SC Elise. The '05 Elise NA that was tested, was a "ringer" as posted above. The published numbers by Lotus for a 2005 Elise NA is listed at 0-60 in 4.9 seconds, and 4.7 seconds with the optional Sport Pack (with lighter forged wheels). The Federal Lotus Elise SC from Model Years 2008 to 2011 is officially listed by Lotus as doing 0-60 in 4.4 seconds.
These numbers are often mixed up in advertisements and superseded with independent test numbers, so the confusion is very understandable.
A great example can be found in this quote from Car & Driver after testing an Elise SC:
"Surprisingly, the SC’s 0-to-60-mph time of 4.5 seconds was a 10th slower than the naturally aspirated Elise we tested in ’04 but quicker than the 4.8-second sprint of a naturally aspirated Lotus Elise we tested last year. We’re thinking that first Elise may have been an unnaturally fleet example."

Lastly, Lotus of Portland would advertise an Elise SC, taking the "ringer" test numbers quoted in the above test, accept them (disregarding Car and Driver's belief that they may have had an unnaturally fleet example), and claims it as advantageous in making the Elise SC slightly more drivable day to day. The excerpt is as follows:
"..... The base Elise gets to 60 mph in 4.4 seconds, and the SC trim is a tenth of a second slower, but has a smoother power curve, making it slightly more drivable day-to-day....."
And thus the quicker NA vs.SC myth perpetuates....
It's just unfortunate that 0-60 in 4.3 or 4.4 seconds is not true of the production
Elise NA version.
