Buffett-Backed BYD Explores IPO of Electronic-Component Unit

BYD Co., the Chinese electric-carmaker backed by Warren Buffett, is considering an initial public offering for a unit that makes a power-management device that’s produced by just a handful of companies globally, said people familiar with the plan.

In our review car, the explosive LT4 eight-cylinder works through a 10-speed automatic transmission co-developed with Ford, but a standard six-speed manual is on offer, too. With the automatic, the ZL1 can scoot you and your Frappuccino up to 60 mph in 3.5 seconds. It also has serious handling chops, even with the roof cut off, with an incredibly flat cornering attitude and sticky rubber—Goodyear Eagle F1 Supercars, sized 285/30 up front and 305/30 at the back—that keeps all 4,148 pounds veritably glued to the pavement. The ZL1’s front end is all intake, with the black flow-tie—that’s a bowtie emblem with its ce...
