High-end luxury carmaker Bentley has been hyping its upcoming sport utility vehicle for many months now. Although the company has been keeping the key details and design under wraps for the most part, Gizmag has come across some spy shots of the car being tested in the field.

As this writer was traveling with the US leg of the Gumball 3000 rally over the weekend, a few of my traveling companions took a sightseeing side trip to the Hoover Dam, on the border of Arizona and Nevada. They came back with tales of a chance encounter with the Bentayga, which was taking a break at the dam during a test run through the American southwest.

It's been almost two years since Bentley confirmed that it was going to make an SUV designed to be as powerful and comfortable as anything ever seen in the segment, following the company's presentation of a concept SUV, the Bentley EXP 9 F, at the 2012 Geneva Motor Show.

Based on these new photos, it looks as though the Bentayga has a slightly more aggressive stance, with some subtle design refinements over the EXP 9 F. These make it appear sportier than the concept car seen at Geneva, which had the appearance of a more traditional crossover given a major upgrade in the classic Bentley style.

Last month, Bentley shared this cryptic video for its upcoming SUV. The company claims it will include technology to make the Bentayga its most advanced vehicle yet.

Anything remotely resembling details and specs on the promotional microsite for the Bentayga, or elsewhere, are hard to find, but you can see it in action (from a distance) in this off-road test video Bentley released earlier this year.

Bentley says that the Bentayga will finally be unveiled in late 2015. You can see the full gallery of Hoover Dam spy shots at The Car Guide. Special thanks to Benjamin Hunting for letting us share a few of these shots with you here.
