In large part, the delay following the initial showing at Laguna Seca in 2011 and today’s quiet start of production can be blamed on the engine—but in a good way. While the 1,650cc V-4 shares parts with Chevy’s LS-1 V-8, they are fewer in number than you’d think. And in no way is this a small-block Chevy run through a massive bandsaw; it’s an engine developed specifically for this application. The reasoning behind starting with Chevy parts? Pretty simple, actually: So much is known about combustion-chamber design, valve train geometry, bearing sizes, and other factors that a fair portion of the engineering was, in essence, already done.
