Work continues on the 2017 Hyundai Equus as our spies have caught the model undergoing hot weather testing in the United States.

While we've already seen the car on several different occasions, the latest batch of spy photos gives us a pretty good glimpse at the interior.  As you can see, Hyundai is really stepping up their game as the cabin is downright luxurious as it boasts perforated leather seats with contrasts piping.  The sedan also has elegant wood trim, metallic accents and higher quality switchgear.  Other notable highlights include a Lexicon audio system, heated / ventilated rear seats and Audi A8-inspired wood and metallic trim on the rear seatbacks.

The front passenger compartment is heavily camouflaged but features a two-tone leather-wrapped steering wheel and an infotainment system with a wide display.  We can also see a redesigned center console and a steering-wheel mounted shifter.

Hyundai has been tight-lipped about the model but it will likely be powered by a 5.0-liter V8 engine that develops at least 420 bhp (313 kW) and 383 lb-ft (518 Nm) of torque. It will be connected to an eight-speed automatic transmission which can be paired to a newly optional all-wheel drive system.
