2021 Ford Bronco 4-Door Black Diamond 4×4 – Bottom Line Review

2021 Ford Bronco 4-Door Black Diamond 4x4 2.3T: After a quarter century hiatus, the sixth generation of Blue Oval Unbroken Horse heritage off-road SUV returns to tackle treacherous slopes.

BUCKING, YET TO BE BROKEN: In contrast to the feral roaming Mustang, the “Bronc” is a domesticated American horse bred to buck riders and delight rodeo passerby -ers. The Spanish language word for “rough”, has been adopted in Western American cowboy tradition, often with the final “o” ignored, to describe a horse not yet broken for riding. Announcing the return of the traditional off-road four-wheel drive sport activity truck to the Blue Oval the final “o” is retained as an all new 2021 Ford Bronco 4×4 is released from the gate. With the first two years’ Bronco production sold out, three things are certain. In the good ole U.S. of A. there is plenty of appetite for automotive nostalgia and more than sufficient room for a Jeep Wrangler competitor. Besides, at Roadblazing.com , we respect vehicles which few mountains or rivers can shake a stick at.

WHAT: 2021 Ford Bronco 4-Door Black Diamond 2.3T 4×4. Returning after a quarter century absence, this is technically the sixth generation “Unbroken Horse” since 1966 to wear a Blue Oval badge.

1966 Ford Bronco: the original in a Ford Mo Co period advertisement

That is not even counting the 1984-1990 Bronco II. The all new 2021 Bronco code designated U725, is based on the T6 Ford Ranger pickup truck with a fully boxed-out frame as well as aluminum hood and tailgate. It is available in two and four door liftgate models, with soft or removable hard tops. A more powerful desert running Raptor version on the way.

Standard Powertrain: intercooled twin-scroll turbocharged 2.3L DOHC 16V DI gas I-4 w/ idle Start/ Stop = 270 hp / 310 lb-ft @3000 rpm (300 hp / 320 lb-ft w/ 93 AKI octane unleaded gasoline).

2021 Ford Bronco 4-Door Black Diamond 4×4 2.3T: 270 hp on regular / 300 hp on premium unleaded fuel + 7 speed manual gearbox + AdvancTrak electronic two speed 4WD
    • = -15 (+15 on 91 AKI) hp, +50 (+60 on 91 AKI) lb-ft vs. Jeep Wrangler JL 4-Door 3.6L V-6
    • = hp, +5 (+15 on 91 AKI) lb-ft vs. Jeep Wrangler JL 4-Door 2.0L I-4

Optional Powertrain: intercooled twin turbocharged 2.7L DOHC 24V DI gas V-6 w/ idle Start/ Stop = 315 hp / 410 lb-ft @3000 rpm (330 hp / 415 lb-ft w/ 93 AKI octane unleaded gasoline)


2021 Ford Bronco 4-Door Black Diamond 4×4 2.3T: independent front 2 wishbone suspension, bash plates
    • STANDARD: 7-speed manual helical gear transmission (6 + 1 crawl spline gear at 94.75:1 ratio)
    • OPTIONAL: 10-speed torque converter planetary automatic transmission
    • 4WD Transfer Case STD.: 2-speed part time electronic, shift on fly high ratio, 2:72:1 low ratio
    • 4WD Transfer Case OPT.: Advanced 2-speed auto-mode on demand, 3.06:1 low ratio

WHAT (A) STYLING DIFFERENCE: Creating a modern successor to a heritage SUV, Ford has unleashed a brawny new upright cube with an agreeable amount of retro cues. Like the original, the 2021 Ford Bronco 4-Door Black Diamond hood to fender joint rises flaring outwards. Differing from the former, there is an aft hood power dome. Adopting the 66’s thin grille / outboard round headlamp combo, a more serious chrome “BRONCO” lettered center horizontal bar in darkened upper and lower egg-crate, spanning to thin LED DRLs replaces the old chrome egg-crate.

Slim clad extensions don’t attempt to out-fender the Jeep Wrangler JL. Also unlike the Wrangler (and original ’66), door hinges are mounted internally. A clever cue has the darkened wing mirror arms extending from the windshield wiper arm cover across the A-pillars. Tandem lateral belt and lower cheat line creases and darkened rock rails wrap the body. The green house is usefully tall and an upward kink commences after the C-pillar.

Miniaturized vertical F-150 taillights cover the rear corners; Rear aperture is a split upper liftgate with lower backlight mount wiper, and lower left to right swing-gate, with tidy external hinges spare tire mount; Lower bumper contains center dip for spare tire fill and left side license plate crater.

2021 Ford Bronco 4-Door Black Diamond 4×4 2.3T: starting at $35k, the Black Diamond tester rings up at $43k.

Off-Road Functional: heavy duty tapered front bumper; powder coated. clad rear bumpers, 2 front, 2 rear tow hooks; darkened fender tie-down hooks; front, rear, transfer case, fuel tank bash plates; manual fold wing mirrors; swing-gate mounted full spare tire on wheel

WHY: Ford dealers finally have the goods to lull Wrangler customers away from Jeep dealers.

WHEN: On-Sale (in the U.S.) since late Autumn 2021

WHERE: Ford new consumer truck dealers

WHERE MADE: Wayne, Michigan, U.S.A.

WHERE TO: Optional Advanced electronic four wheel drive was aboard the tested 2021 Bronco 4-Door Black Diamond . Akin to the Ford F-150 Raptor  transfer case, AdvanceTrac 4×4 Automatic mode reads slippage and yaw rate data to vary transfer case clutch pack slippage & rear to front torque split. Roadblazing.com discovered how first gear was perfectly adequate on snowy 10° steep hill. When ambling anything steeper a 7th crawl gear is located down and far left on the shift pattern. Trail Control foot-off-the-pedal hill descent is a work in progress, as any braking simply triggers de-activation. G.O.A.T. modes altered by rotating a collar on the center console four wheel drive selector vary throttle response and transfer case slippage for varied terrains.

2021 Ford Bronco 4-Door Black Diamond 4×4 2.3T: 3:06 transfer case low ratio, 90:1 7th crawler gear & A/T rubber happy to climb off road trails
  • +1 G(o). O(ver). A(ny). T(errain) management:  7 Modes = Normal, Eco, Sport, Wet, Sand, Mud, Rock
  • +1 Dash board separate differential lock & traction control deactivation
  • -1 Baja dune jumping mode only on Badlands & Wildtrack trims
  • +/- Trail Control crawl cruise control uses steering wheel spoke toggle to adjust speed, but depressing the brakes disengages it completely
2021 Ford Bronco 4-Door Black Diamond 4×4 2.3T: 7 G.O.A.T. varying terrain drive modes

Suspension Creds:

  • F: Twin forged alloy A-arms with long-travel coil-over springs, HOSS-tuned heavy-duty dampers; R: 220 mm solid rear axle with long-travel, variable rate coilover springs, HOSS-tuned heavy-duty dampers
  • Off-road steering knuckles
  • 32″ inch General Grabber highway all-terrain tires
  • 8.4″ inches ground clearance
  • 7.95″ inches front, 9.8″ inches rear wheel travel
  • 35″ inches water fording

HOW STRONG: Base four-banger power, out of a detuned Mustang mill, is flexible in town thanks to a light clutch, quick disengagement and low effort shifter. Above 1st gear, the ratios are usefully short avoiding frequent upshifts. On the open road wind noise becomes considerable above 70 miles per hour. Despite the hard roof panels’ optional felt insulation.

HOW LIMBER: Electric rack and pinion steering, more communicative in the rough than smooth, clocks quicker and lighter than on a JL Wrangler antediluvian recirculating ball type. Where the Jeep soldiers on with a mid 20th century solid front axle, the 2021 Bronco’s modern independent double wishbone front end tracks more steadily. Bronco Black Diamond coil-over damper posterior wheel control settles the Hotchkiss solid axle body bob for a civilized riding off-road machine. Four-wheel brake rotors don’t alleviate a wooden pedal and the slowing effect seems a bit unhurried.

HOW FAR: 18 mpg combined fuel economy; 450 miles highway range for a 2021 Ford Bronco 4-Door Black Diamond 2.3T 4×4 7-speed manual

  • observed combined fuel economy =  +0% vs. Jeep Wrangler JL 4-Door V-6

HOW BIG/ LITTLE: 2+3 occupancy; Requires less parking space the Jeep Wrangler; Segment leading nominal cargo room

2021 Ford Bronco 4-Door Black Diamond 4×4 2.3T: Row 2 bench seating

  • Row 2 legroom: 36.3″ inches = -2.0″ vs. Jeep Wrangler JL 4-Door
  • Cargo Volume (nom. – max.): +12%, +7% vs. Jeep Wrangler JL 4-Door

Ford Co-Pilot360: Blind Spot, rear cross traffic Warning; Post collision S.O.S. alert; Lane Departure Warning & Keep Assist; Evasive Steering Assist; Adaptive Cruise Control; Driver Alert warning 360° surround camera;  Forward park sensor

HOW FRIENDLY: Operationally, the new Ford Bronco cabin very nearly gets the job done, with straight-forward display and control array, borrowing much from a Ford Escape CUV, including a “Bronc” faced steering wheel, tidy spoke controls and climate control cluster. Dashboard corner and center console passenger grab bars and vent louver levers tipped in pastel sky blue embark on inspirational, especially in contrast to a drab undistinctive hard passenger side dash face, and walls coarsely grained to invite scuffs. It is understood that removable doors force a relocation of power window switches. But whose idea was it to slap them onto the face of the center console storage bin, hidden by the armrest overhang? The single analog dialright flanked by 8.0″ multi-function TFT digital display, configurable for G.O.A.T. drive modes doesn’t say “heritage” the way any old twin round dial gauges would.

FINAL SAY-SO: After a quarter century hiatus, Blue Oval’s heritage SUV is back to tackle treacherous slopes.
