Inspecting the first Aston Martin DB11s with CEO Andy Palmer

Next stop is the passenger door. Palmer repeatedly opens and closes it to hear the panel thump home. “It’s overflush because of dirt build-up,” he explains, pointing to a door trailing edge that sits slightly proud of the rear wing. He also closes the door with its handle held open. If there are metallic noises, the door catch is probably snagging. But no such sounds emerge and Palmer declares this door “particularly good”.

He should know, this being the 83rd DB11 he’s inspected. He certainly looks practised as his scrutiny turns to the Aston’s rear end. “I carry these with me everywhere,” he says, producing an evenly pronged disc, about the diameter of a doughnut, and a small rectangular block. Each of the disc’s prongs is marked with its thickness – 1.0mm, 2.5mm, 3.5mm and so on – enabling the accurate measurement of panel gaps. The small block uncovers any flush irregularities. The prongs reveal a 3.5mm gap on one side and 3.0mm on the other. Palmer refers to a neatly presented app on a tablet on which every tolerance value can be found, complete with images. These are within limits.

So are the gaps around the highmounted stop light, but Palmer notes some residual polish beneath a window and declares the closing performance of the driver’s door “just okay”, the panel not shutting quite as cleanly as its opposite number. Next up is the clamshell bonnet’s underflush to the front wings, and its relationship to the bumper. “It’s the hardest thing on this car,” he says. “It’s a huge panel, with lots of tolerances.” The gap on one side is 4.0mm, the other 3.5mm – a pass.

Then Palmer uncovers a fault, and an inconvenient one at that. There’s a paint flaw on the bonnet, like a faint birthmark. “We take more than 100 hours painting these cars,” he says, “so we make sure they’re perfect.” Perfecting this panel will take considerable skill and some effort.

Up next is the interior. Door seals are surveyed to ensure that their lips haven’t folded beneath the trim that they should overlap. Every button is pressed, knob turned and paddle pulled. The sunvisors’ vanity mirror sliding covers are slid, because “they need to move with the right force”, and the electric seats motor about in the search for unseemly grinding. Gaps and flushes are checked around the trim and the CD player is tested with a speaker-threatening track called ‘Ugly Duckling’. “Apart from the damage to the paint, this is a good car,” declares Palmer.

So only another 917 DB11s to go. Why does he do it? “This is Aston Martin’s first brand-new car in 12 years. People don’t easily buy the first year of production, so I’m doing this to inspire confidence for the consumer and say that it’s okay. It’s a hard commitment to quality.”

There’s more to it than this. “I want to instil in the workforce the idea that quality is everything. If I’m prepared to spend four hours a day, it must matter. It’s quicker to build a quality car, too. Everything I’ve learned with the Japanese is going into this, from Honda during my time at Austin Rover to Nissan,” where Palmer was chief performance officer before joining Aston. “There’s a lot of kaizen here,” he says of Aston’s continuous improvement ethic. “It doesn’t matter if you make a mistake. You just need to learn from it. I want to take away the fear factor from the British motor industry.”

Palmer explains all this as he drives the DB11 through the factory towards the so-called squeak and rattle test track. It’s designed to be driven at 5mph, apart from the 2.5mph final section, whose trapezoidal humps impose squeakprovoking twist on the body. Before that come slender transverse rails, strings of rope, a tight, uneven turning area and some pavé. This car produces no stray sounds once he smilingly removes the loose key in its centre console, so no issues here.
