Mini Cooper owners can design custom 3D-printed parts

- By Clifford Atiyeh

We’re nearing the point where clicking “File > Print” will bust out a custom dashboard in our basements. We’re really not there yet, but Mini is close.

Owners of current-generation Cooper Hardtop two-door, four-door, and convertibl­e models can now order custom 3Dprinted trim pieces, laser-etched door sills, and LED puddle lights with their own personal designs. While the John Cooper Works GP Concept included 3Dprinted door panels and instrument-cluster parts, Mini is not going that far for production models. Known as Mini Yours Customized, the faux air vents on the front fenders (called side scuttles), dashboard trim on the passenger side, illuminate­d door sills, and door light projectors all can be patterned, labelled, textured, and colored to taste, or any lack thereof.

Beyond all the regular Mini accessorie­s, these parts can display the owner’s name, signature, and other favorite graphics or shapes for an as-yet-unnamed price. Mini will let owners configure their designs from pre-selected themes or go wild into the unknown, either online or at a Mini dealership. Weeks later, after a Mini-approved 3D printer opens the file and readies the plastic (for the fender and dash trim), aluminum (for the laser-etched door sills), or those little LED slide covers (for the projected puddle light images up to 20 inches in diameter), the custom parts arrive fresh from Germany ready to snap or stick onto the car. They’re easily detachable and and can be swapped for the standard parts, so long as you’re comfortabl­e with reattachin­g a few wires here and there.

It’s not a total free-for-all, as Mini still has design and quality standards it’d like to maintain. The Countryman and John Cooper Works models are excluded, while Clubman owners only can order the LED door sills. Other necessitie­s, such as a bracket for the dash trim that allows a quick, tool-free swap, are required if your Mini is to truly be this custom cool. Currently, Mini USA sells several accessory door sills for up to $345, fender vents for up to $270, and patterned dash trim for up to $350. Expect to pay a bit more for one-off parts.

7.7-second zero-to-60-mph run and a 180-foot stop from 70 mph — decent for a mid-size pickup on all-terrain tires — but the brake pedal has the same strange stepped resistance as other Tacomas. The TRD Pro’s Fox shocks feel slightly firmer than the TRD Off-Road’s Bilstein pieces, diminishin­g that model’s body movements without degrading ride quality, but our test truck still listed heavily during its modest 0.70-g skidpad orbit.

Other Tacoma idiosyncra­sies are part and parcel of the experience, including the V-6 engine’s grainy nature as well as the low seating position and the high floor — the latter two of which lend the cabin a feeling of tightness you won’t find in, say, a Chevrolet Colorado (a truck that soon will be getting a ZR2 edition that should stack up neatly with the TRD Pro in a head-tohead comparison). The six-speed automatic transmissi­on suffers from dimwitted programmin­g and excessivel­y tall fifth and sixth gears. At highway speeds, the transmissi­on will dramatical­ly downshift from either overdrive ratio to fourth gear when the Tacoma detects even a whiff of an uphill grade or a request for even mild accelerati­on.

A button on the dashboard labeled ECT Power alters the shift programmin­g to mitigate early upshifts and hasten downshifts between higher gears, perking up the gearbox’s responsive­ness. This partial sport mode also relies more on fifth gear when the normal programmin­g would be pushing for a rushed sixth-to-fourth jump. Toyota says that activating the ECT Power mode improves performanc­e but can affect fuel economy, which is a friendly way to indicate that the baseline transmissi­on settings (which the transmissi­on defaults to each time the engine is started) are tuned for the EPA fuel-economy test cycle.

It doesn’t help that the 3.5liter V-6 makes most of its power high in the rev range, and the TRD-branded sport exhaust doubles as the town bugler announcing the transmissi­on’s frenetic behavior on the freeway. Each time fourth gear is called into service, the soundtrack goes from a relentless drone to a gritty braappp. Our interior-noise-level readings matched those of other Tacomas we’ve tested at wideopen throttle and at a steady 70-mph cruise, but the droning of the Pro’s exhaust note is more annoying. We tried to lock the transmissi­on into sixth with the shifter in manual mode during a long drive, only to have the computer override our decision and loudly downshift anyway. Here’s an idea: Stick with the standard six-speed manual, and save both headaches and money. DUNE’T YOU WANNA GO OFF-ROAD?

Evaluating a proper off-roader like the TRD Pro on the mean streets of suburbia is one thing, but pavement cruising is to the Toyota’s mission as a fork is to eating yogurt. So we set a course for Michigan’s Silver Lake State Park and its playground of coastal sand dunes. With the tires’ inflation pressure significan­tly aired down to improve traction and a tall flag bolted to the front tow hook for more visibility, we put the transfer case in fourwheel drive high and fired the Tacoma over the open terrain it was designed to tackle.

The Toyota is by no means as intense or capable as Ford’s F-150 Raptor, a veritable stadium truck with airbags and heated seats. But the TRD Pro’s suspension is claimed to enhance rearaxle articulati­on and to better absorb large bumps both when crawling and at higher speeds. We found the Fox shocks could handle quick succession­s of washboard terrain — natural expanses of speed bumps known as whoops — up to nearly highway speeds before smacking their bump stops and causing the chassis to buck fore and aft. The shocks, which feature remote reservoirs at the rear axle for additional fluid capacity and cooling, also soak up landings from mild jumps with aplomb. And the Tacoma can indeed jump.

Climbing the tallest dunes posed no major traction-related hurdles, although we found the throttle must be pinned early in order to tap the V-6’s swell of high-rpm torque and build momentum before hitting really steep sections. The Tacoma’s five-mode Multi-Terrain Select traction-control settings, a range of electronic assists for everything from mud and sand to rock crawling, were unnecessar­y in the deep sand; instead we favored the freedom afforded by simply deactivati­ng the electric watchdogs altogether. With 9.4 inches of ground clearance, it takes some commitment to scrape the Tacoma’s dirty bits, and we escaped having only once bumped the front skid plate on a particular­ly ambitious approach. This isn’t shocking given the Tacoma’s 35-degree approach angle, which trails the smaller Jeep Wrangler Unlimited’s absurd 42-degree measuremen­t, although the Toyota sits just 0.6 inch lower and boasts a slightly better breakover angle. Perhaps the TRD Pro’s greatest demerits in the rough are its small, awkward tow hooks buried under the front bumper’s extreme overbite, which make attaching a flag mount or any type of tow strap frustratin­gly difficult. That’s a serious oversight for a vehicle designed to traverse challengin­g terrain.

Whether you use it to play in the sand or bash rocks, the TRD Pro stands out as one of the few convincing­ly off-road-focused trucks you can buy new from a dealership. Even so, the TRD components don’t get in the way of the Tacoma’s day-to-day livability. Harder to swallow is that the truck costs $43,700 to start, and our example expanded that figure to $44,627 with optional mud flaps, side steps, floor mats, and a cargo-bed mat. That’s a few shoulder shrugs and a mysterious reduction in your children’s college fund away from a $49,520 Ford F-150 Raptor SuperCab, meaning this Taco’s size, bulletproo­f reputation, and specific sort of crunch will need to touch a nerve in a very particular sort of buyer.

2017 Toyota Tacoma TRD Pro 4x4 Automatic Price as tested: $44,627 (base price: $43,700) Zero to 60 mph: 7.7 sec Top speed (governor limited): 113 mph Fuel economy: EPA city/highway driving: 18/23 mpg
