The 2013 Range Rover has just been unveiled and it is already enjoying a huge success: the waiting list is so long that Land Rover can't handle it. However, a leaked full guide has unveiled that the 2014 model year will bring more updates than Land Rover let on to.

The biggest update will be the replacement of the base 5.0-liter V8 engine with a supercharged 3.0-liter V6 - not a big surprise though, considering all the latest emissions and fuel consumption regulations. While the current V8 engine develops a total of 375 horsepower and 375 pound-feet of torque, the V6 will be limited to 340 horsepower and 332 pound-feet of torque.

Despite the 35-horsepower drop, the V6 engine will deliver impressive fuel economy: 16 mpg city, 22 mpg highway and 18 mpg combined. CO2 emissions also decrease by 22 percent. Still, begin environmentally friendly typically means you'll have to be slower, leading to a 0-to-60 mph sprint of 7.1 – 0.6 seconds slower than the current V8 model. The V8 engine will continue to be offered with the Supercharged and Autobiography trim levels. The transmission will remain the same for both engines: a eight-Speed ZF 8HP70 automatic transmission.

It looks like for the 2014 model year Land Rover will also be reducing the prices a little bit: Adaptive Cruise Control goes down from $2,000 to $1,295 and Tow Pack will be $1,300.

The 2014 V6 version will be priced at $83,545 and the V8 version will be priced from $99,995.
