According to Automotive News, a reskinned V8 Vantage is exactly what the DB10 is. Instead of basing the limited-production spymobile on the new architecture it's developing and fitting it with the new engine it's sourcing from Mercedes-AMG, the DB10 is built around the same VH platform and V8 engine as the aging Vantage. Though it's evolved over the years, the VH platform dates back to the V12 Vanquish that launched way back in 2001. The second generation of that platform underpins the Vantage on which the DB10 is reportedly based, powered by a version of Jaguar's AJV8 engine that dates back to 1996.
What is new about it is the design language that the new DB10 previews. More than any recent concept – like the DP-100 Vision Gran Turismo, CC100 Speedster or the most recent Zagato one-offs – the DB10 is said to embody the new direction in which Marek Reichman and his team plan to take the company's styling, moving away from the current theme it has employed for the past couple of decades. So while the DB10 you see here may not be packing much in the way of new technology, the subsequent models that will follow its lead hopefully will.
