Spotted by a reader in a California parking lot, the prototype test car features updated front vents flanking the spindle grille, as well as reworked side skirts and a deeper rear bumper. This is by no means confirmation that we’re looking at the new LC F, though. Another possibility is that the test car could be a new F Sport model with sportier trim but no mechanical updates. If, however, we are looking at a prototype Lexus LC F, it could be packing a newly developed 4.0-liter V8 rated at 621 horsepower according to reports
. The current Lexus LC 500 can sprint from 0-62 mph in 4.4 seconds and top out at 168 mph.
