We're rather fond of the XC90 here at Top Gear, which is why these sketches excite us greatly. It seems that the designers at Volvo have sharpened their best pencils to scratch out a new XC90.Showcased in California at Volvo's forward-thinking Concept Centre, these sketches give us a rough idea at what the next XC90 will look like. Some are rugged. Some are smooth and aerodynamic. None are set in stone. All are rather splendid.Volvo tells us we're still a while off the next XC90 - maybe a couple of years - so there is much work to be done, but we like what we see so far. After all, there's nothing like an XC90 to carry an army of kids to school.
