Jaguar's long-rumored crossover will reportedly feature sleek styling that blurs the lines between a sedan and crossover.

Jaguar's crossover is reportedly inching closer to production.

Auto Express says the model - which could be called the XQ or Q-Type - is in its "advanced design stages" and will blur the lines between a sedan and crossover. As a result, the model will have a sleek design that features short overhangs and a steeply raked windscreen. We can also expect F-Type inspired headlights and blacked out C-pillars from the XJ.

Engine options remain unconfirmed but speculation suggests the model will be offered with a turbocharged 2.0-liter four-cylinder that develops 240 bhp (179 kW). We can also expect a 340 bhp (253 kW) supercharged 3.0-liter V6 and a 2.2-liter SD4 diesel with a variety of outputs. The crossover could also be offered with a C-X75 inspired hybrid system that uses two electric motors.

Little else is known about the model but it is expected to ride on a shortened version of the XJ platform. Rear-wheel drive will be standard while all-wheel drive will be optional.

The crossover is expected to be launched in 2015, so expect to learn more as development progresses.
