Review: Holden RG.I Colorado 7 (2012-13)
Overview
Released in December 2012, the Holden RG Series I (RG.I) Colorado 7 was a seven-seat SUV. Manufactured in Rayong, Thailand, the Colorado 7 was powered by a 2.8-litre four-cylinder ‘Duramax’ turbo-diesel engine that was mated to a six-speed automatic transmission. The Colorado 7 had a part-time four-wheel drive system with a two-range transfer case, while the range consisted of LT and LTZ variants.
Duramax diesel engine
The 2.8-litre Duramax diesel engine had common-rail direct injection, a variable geometry turbocharger with an intercooler, double overhead camshafts, four valves per cylinder and a compression ratio of 16.0:1. Furthermore, the six-speed automatic transmission had an ‘Active Select’ feature which enabled the driver to change gears sequentially via the gearshift lever.
Chassis and dimensions
Jointly developed with the Holden RG Colorado utility , the Colorado 7 had a ladder-frame chassis. Despite its seven seat capacity, however, the Colorado 7 had a 251 mm shorter wheelbase (at 2845 mm) than the Colorado utility, was 4878 mm long and 2132 mm wide. Furthermore, LT variants were 1834 mm tall and had ground clearance of 219 mm, while LTZ variants were 1847 mm tall and had ground clearance of 231 mm. The Colorado 7 had a rear cargo area of 235 litres, though this increased to 878 litres when the third row of seats was folded into the floor.
Suspension and towing capacity
The Colorado 7 had double wishbone front suspension and five-link independent rear suspension with coil springs (rather than the leaf springs of the Colorado utility). Furthermore, the Colorado 7 had a maximum towing capacity of 3000 kg.
| Variants | Engine | Trans. | Peak power | Peak torque | Fuel con.* |
|---|---|---|---|---|---|
| LT, LTZ |
2.8-litre turbo-diesel I4 | 6sp auto | 132 kW at 3800 rpm | 470 Nm at 2000 rpm | 9.4 L/100km |
Part-time four wheel drive
The part-time four-wheel drive system was controlled via a rotary switch positioned in the centre console. As such, the driver was able to shift ‘on the fly’ between the following modes:
- Two-wheel high: rear-wheel drive with high range gearing;
- Four-wheel high: four-wheel drive with high gearing;
- Four-wheel low: four-wheel drive with low range gearing (a 2.62:1 reduction ratio); and,
- Neutral: no drive to the wheels so that the vehicle can be towed.
Safety equipment
Standard safety equipment for the Holden Colorado 7 included dual front airbags, full-length curtain airbags (i.e. for all three rows of seats), ABS, electronic brake force distribution, brake assist, electronic stability control, traction control and front seatbelts with pretensioners and load limiters.
Brakes
The Holden Colorado 7 had 300 mm ventilated front brake discs and 318 mm rear discs.
ANCAP crash testing
Based on ANCAP crash testing conducted for the RG Colorado utility , the Colorado 7 received a five star adult occupant protection rating with a score of 35.09 out of 37. In the offset crash test, there was a slight risk of serious chest injury for the driver and a slight risk of serious leg injury for both front occupants. In the side impact and pole tests, however, maximum points were awarded.
Features: Holden Colorado 7 LT

Review: Holden RG.II Colorado 7 (2013-16)
Overview
Released in October 2013, the Holden RG Series II (RG.II) Colorado 7 introduced a more powerful 2.8-litre ‘Duramax 2’ turbo-diesel engine, additional safety equipment and Holden’s MyLink connectivity system.
In addition to the more powerful engine, the automatic transmission was recalibrated and included a ‘shift stabilisation’ function for hill ascents or descents that prevented unnecessary gearshifts. For off-road driving, a Descent Control System was also introduced which could maintain the speed of the vehicle on descents without the need for brake inputs from the driver.
| Variants | Engine | Trans. | Peak power | Peak torque | Fuel con.* |
|---|---|---|---|---|---|
| LT, LTZ |
2.8-litre turbo-diesel I4 | 6sp auto | 147 kW at 3600 rpm | 500 Nm at 2000-2200 rpm | 9.2 L/100km |
Safety equipment
Compared to its RG.I Predecessor, standard safety equipment for the RG.II Colorado 7 was extended to include front seat-mounted side airbags. New chassis control systems included:
- Trailer Sway Control which would apply the brakes and reduce engine torque in the event of towing instability); and,
- Hill Start Assist which automatically engaged when a gradient was detected to keep the vehicle stationary during the period from brake release to throttle application.
Features
Standard features for the RG.II Colorado 7 were extended to include a seven-inch colour touch screen with Holden’s MyLink connectivity system. The MyLink system enabled drivers to connect Bluetooth-compatible devices to access applications or stream music. Embedded applications for MyLink included Pandora, Stitcher and TuneIn. Furthermore,
- For compatible iPhones, Siri Eyes Free Mode could be used to play music, compose text messages, read notifications and add reminders; and,
- The BringGo navigation application could be purchased separately to provide 3D maps, turn-by-turn directions, points of interests and emergency contacts.
November 2014 (‘MY15’) update
In November 2014, the Colorado 7 was updated for the ‘2015 model year’. As part of the update, the Colorado 7 LTZ received a new ‘Comfort Suspension’ tune which included revised spring rates, dampers and a stiffer front stabiliser bar. According to Holden, the ‘Comfort Suspension’ improved ride balance and isolation for a more comfortable ride.
Standard features for the Colorado 7 LTZ were also extended to include heated front seats, while the interior was upgraded with ‘Jet Black’ soft touch finishes for the centre console and surface fascias.
For the entire Colorado 7 range, changes included:
- Aerodynamic updates and improved door seals to reduce noise and vibration;
- Refinements to the Hill Descent Control (HDC) and Hill Start Assist (HSA) systems; and,
- A new Satin Steel Grey paint finish.
Accessories
Extra-cost accessories for the RG.II Colorado 7 included an alloy SuperBar, steel bulbar and black nudge bars. Manufactured from structural grade alloy, the Alloy SuperBar was certified by ANCAP to maintain the Colorado 7’s five star safety rating.
2016 Holden Colorado 7 Trailblazer
The Holden Colorado 7 Trailblazer was released in April 2016. Based on the Colorado 7 LTZ, the limited edition Colorado 7 Trailblazer was distinguished by its 18-inch ‘High Country’ alloy wheels, two-tone leather seats, unique floor mats, masked headlights, body-coloured roof spoiler, bonnet protector, ‘Trailblazer’ side badges and ‘Trailblazer 4×4’ rear decal.
