An expanded Bentley Flying Spur sedan range will appear at the 2014 Geneva Motor Show next week by offering a less-thirsty V-8 engine option, alongside the existing W-12. We've known about this model for some time, and it seems like a logical addition to the lineup.

Wearing the straightforward title Flying Spur V8, the new model will feature the same 4.0-liter, twin-turbocharged engine as the two-door Continental GT V8. As in the GT, the V-8 produces 500 horsepower and 487 pound-feet of torque, and is coupled to an eight-speed automatic transmission with all-wheel drive.

That combination will get this titanic sedan to 60 mph from a standstill in 4.9 seconds, and allow it to reach a top speed of 183 mph. Bentley also claims a 520-mile cruising range, thanks to the V-8's smaller displacement and efficiency-improving technologies like cylinder deactivation.

The Flying Spur V8 gets a few subtle exterior markers to differentiate it from the top W-12 model. These include "figure-eight" chrome exhaust tips, red badging--a traditional indication of a Bentley V-8 model--and front-bumper grilles finished in black, with a black "wings" insert.

Naturally, there's also a posh interior. Bentley has made an effort to give buyers the tech they crave, including a Touch-Screen Remote that allows rear-seat passengers to control the car's climate and infotainment systems, as well as an optional rear-seat entertainment system.

Buyers can further dress up a Flying Spur V8 with the Mulliner Driving Specification, which includes sporty accoutrements like 20-inch alloy wheels, drilled alloy pedals, and a knurled gear selector.

Flying Spur V8 deliveries begin this spring. While four fewer cylinders should make the V8 less expensive than the flagship W12 model, Bentley hasn't disclosed how much.

The two-door Continental lineup isn't done updating either. Also at the Geneva show, Bentley will unveil an uprated 2015 Continental GT Speed and the rest of an updated 2015 Continental range.
