My Other Digger’s a Jeep

We love alternative builds here at TLCB. They’re at the very core of what LEGO is all about, turning the pieces used to create one thing into another thing entirely.

Flickr’s Dyen’s Creations earns our admiration today, having flipped their 42122 Jeep Wrangler Rubicon into something altogether different, creating this excellent (and operational) Technic backhoe loader from only the parts found within the 42122 set.

There’s a working front arm complete with a tilting brick-built bucket, an unfurling rear arm, working stabilisers and functioning steering too.

We think we might like it even more than the set upon which it’s based, and if you agree you can take a look at Dyen’s ‘LEGO 42122 – Backhoe Loader’ album via the link above, plus you can check out all the other things that the 42122 Jeep Wrangler Rubicon set has become by clicking this bonus B-Model link!

My Other Vehicle’s a Giant Excavator

The 4,100-piece LEGO Technic 42100 Liebherr R 9800 Excavator is the largest and most expensive Technic set ever released. With seven motors, two ‘Smart Hub’s, and programmable control via the PoweredUp app, it’s LEGO robotics for the post-PC era.

It is also the ideal set to create an alternative model from, because if you’re going to pick a set for parts, it might as well be the one with the most!

Cue TLCB Master MOCer Nico71, and this amazing… er, honestly we’re not sure. Nico describes it as a ‘Container Handling Vehicle’, which probably doesn’t do it justice, what with it looking like a cross between something from ‘Thunderbirds’ and that ‘Hibernia‘ place that seems to feature here from time to time.

Four suspended tracks, each of which is driven with the front two also steering, are controlled remotely, as is a huge two-stage hook-lift arm and a motorised container locking mechanism.

Building instructions are available and there’s more to see of Nico’s fantastic 42100 B-Model at both Brickshelf and his excellent website. Click the links to take a look, plus you can watch the ‘Container Handling Vehicle’ in action below.

Mighty Metro

It’s the early-’80s, and British Leyland has a new small (and surprisingly good) car on its hands. The Metro, first sold as an Austin and later a Rover, rapidly became a best seller, with over 130,000 sold in 1983 in the UK alone. Aiming to capitalise on this success British Leyland decided to take the Metro racing, and the pinnacle of motorsport in the mid-’80s was rallying’s monstrous ‘Group B’.

Bearing a physical resemblance (but little else) to road-going cars, Group B racers featured tubular-steel space-frames, mid-mounted engines, and trick all-wheel-drive systems, and the Metro got the lot.

Developed by Williams Engineering, the Metro 6R4 gained a mid-mounted naturally-aspirated V6 engine, loosely developed from the all-conquering Cosworth DVF Formula 1 unit, a glassfibre body, and MG badges – to better align it with the hot-hatch versions of the road-going Metro. For homologation purposes customers could actually buy a road-going 6R4 too, which must’ve been a wild thing to take to the shops.

The new Metro 6R4 rally car debuted at the end of 1985, taking a podium at its first event. However, by just the middle of the following year, it was all over.

After a series of fatal accidents, Group B was banned mid-season, and the 6R4 – along with rest of the Group B field – was orphaned. Without a global series in which to race, Rover sold the cars on, but their motorsport life wasn’t over. Rallycross and British rallying became the 6R4’s new home, and in the hands of privateers the cars became formidable opponents, winning so frequently the rules had to be tightened to restrict them.

The 6R4’s V6 engine also went on to a rather interesting new life… but you can read about that another time.

Thus, despite such a short life in world rallying, the Metro 6R4 remains one of the most iconic and fearsome cars ever borne out of Group B, and previous bloggee Samolot has paid homage to the unlikely rally star with his incredible Technic replica.

Under a one-piece removable body Samolot’s 6R4 features a mid-mounted V6 engine, all-wheel-suspension, and a remote controlled all-wheel-drive system with working steering courtesy of LEGO’s Power Functions motors. Custom decals recreate the ’80s works livery, there are opening doors, bonnet and hatch-back, and there’s more of the model to see – including photos of the trick all-wheel-drive chassis – at the Eurobricks forum.

We love simple basic vehicles here at The Lego Car Blog, perhaps because we’re rather simple and basic ourselves.

Cue the John Deere Gator, an all-terrain utility vehicle powered by a 340cc lawn-mower engine, or a tiny diesel, fitted with a CVT, optional four-wheel-drive, and used for everything from estate maintenance to military supply and evacuation.

This splendid little Technic version of the Gator comes from regular bloggee Thirdwigg, who has captured it wonderfully in small-scale Technic, complete with working steering, suspension, and as tipping bed.

Building instructions are available and there’s more to see at Thirdwigg’s ‘John Deere Gator’ album on Flickr. Click the link above to take a look.

Sand Green

Winter is coming here in TLCB’s home nation. The trees are red and yellow, the ground is thick with the shells of various nuts, and a good proportion of the country is under water.

So to cheer us up for the coming weeks when it’ll be dark at 4pm and we’ll be permanently cold, here’s a beach buggy for sunnier climes. Built by Eurobricks’ Jurss it features all-wheel-suspension, working steering, a rear-mounted flat-4 piston engine, plus a removable (and very green) body.

There’s more to see at the Eurobricks forum, and you can pretend you’re somewhere warm and sandy via the link in the text above. Unless you are actually somewhere warm and sandy, in which case can you invite us over?

Multiple Aliases

This is one of those cars that is probably familiar to all of us, and yet may also not be at all. This is a Geo Tracker, built by 2GodBDGlory, and in fact it’s his Geo Tracker, being a Technic recreation of his real-world vehicle.

But it’s also a Suzuki Vitara (the name we know it as here in TLCB’s home nation), a Suzuki Sidekick, a Chevrolet Tracker, a GMC Tracker, an Asuna Sunrunner (what?!), and a Pontiac Sunrunner.

Which is confusing. Thus, because the Tracker/Vitara/Sunrunner is a Suzuki designed, engineered and produced product, with General Motors simply rebadging it and pretending it was theirs, we’re going to call it a Vitara from here on, and 2GodBDGlory’s is excellent.

Powered by two L Motors with Servo steering, and featuring all-wheel-drive, a remotely-operated high/low range gearbox, working suspension, LED head and tail lights, and a removable roof, 2GodBDGlory’s Technic Vitara is as capable off-road as his real one, and there’s much more of the model to see of both at Eurobricks and Bricksafe.

Whatever you know the Suzuki Vitara as where you’re from, click the links above to be impressed.

My Other Car is also an Off-Road Buggy

LEGO’s Technic 42160 Audi RS Q e-Tron revealed here earlier in the year has brought a rather intriguing – if ultimately unsuccessful – prototype racing buggy to bedroom floors in brick form.

Powered by a 2.0 turbo-charged petrol engine, but driven by four electric motors, the real RS Q e-Tron is a hybrid of sorts, using the aforementioned internal combustion engine to generate electricity for those motors. It all sounds very clever, which it is, however Toyota’s traditional twin-turbo V6 petrol-powered Hilux T1s thumped it in the 2023 Dakar Rally.

Still, we like unusual vehicles here at TLCB, and thus we like the 42160 Audi RS Q e-Tron. But we like this even more.

Built only from the parts from the 42160 set, this superb Polaris RZR B-Model is the work of gyenesvi, and it captures the all-terrain side-by-side buggy beautifully in Technic form.

It also redeploys the LEGO Control+ remote control system from the 42160 set, with all-wheel-drive, all-wheel-suspension, and servo steering, which we’ve absolutely made the most of terrorising the Elves here at TLCB Towers.

Building instructions are available if you fancy turning your own e-Tron into a RZR, and you can find out more about the build at both Eurobricks and gyenesvi’s Bricksafe album. Click the links to make the jump, probably over a giant sand dune.

Nosing Ahead

The new BMW M4, as with many of the brand’s latest offerings, is rather… er, nostrilly. Still, in racing form that humungous beak must help with cooling, and the M4 is indeed available to buy as a factory racing car in GT3 specification.

Cue this phenomenal Technic replica of the M4 GT3 by previous bloggee and TLCB Master MOCer Lachlan Cameron (aka Lox Lego).

Deploying not just his own talents, but also the best of third-party LEGO compatible creators including BuWizz (bluetooth battery), System of a Brick (custom rims), snakeeyes (racing livery design), and Brick Visions (interior stickers), Lachlan demonstrates that Lego building can be taken far beyond the basic bricks.

Underneath that superbly-liveried exterior is a full remote control drivetrain consisting of a BuWizz brick and dual Buggy Motors, working steering, adjustable suspension with five ride heights, a straight-6 engine, opening and locking doors, hood and trunk, and LED head and tail lights.

A road car variant is available too, and there’s lots more of both versions to see at Lachlan’s ‘BMW M4 GT3’ Flickr album, at the Eurobricks forum, and via a YouTube video available here. Click the links above to nose your way there.

Micro Machine

Unlike your Mom, Kei-class microbuses are really very small indeed. However they manage to pack a whole lot into their tiny footprint, with room for four adults plus luggage, some feature all-wheel-drive, and a few are even fully-fitted campers.

Cue apachaihapachai‘s terrific Technic microbus which, despite measuring just nine studs by twenty-four, features a complete remote control drivetrain courtesy of an L Motor, a Servo, and a BuWizz bluetooth battery, all completely hidden inside a neat 1990s kei-bus body. There’s even an interior. Kinda.

It’s a miracle of ingenious packaging and you can find out how apachai has done it at the Eurobricks forum. Click the link above to squeeze inside.

A Beautiful Nightmare

Hailing from the golden era of Japanese sports cars, the ‘FD’ Mazda RX-7 was the third and final generation of the rotary-engined icon.

With assistance from twin-turbos, the FD’s 1.3 litre twin-rotor motor produced up to 276bhp, getting very hot and drinking a lot of oil in the process. It was also, in this writer’s opinion, perhaps the prettiest of all the ’90 sports cars, which is enough for many to overlook the ownership nightmare of that unique engine and enter a relationship of intense unreliability and ruinous expense. Which is probably a metaphor for something.

Anyway, this excellent Technic recreation of the RX-7 comes from previous bloggee Matthew Terentev, and includes opening doors, hood and trunk, plus a brilliantly accurate interior in very ’90s-Japan-appropriate black plastic.

There’s much more to see at Matthew’s ‘Mazda RX-7 (FD)’ album on Flickr, and you can click the link above to make the jump.

Happy Being Single

Discovered by one of our Elves on Eurobricks, this is newcomer McMarky’s rather good tracked excavator. Like all good Technic models, McMarky’s creation can operate just like the real deal, being able to drive and steer, rotate the superstructure, and dig – thanks to a three stage boom and excavating bucket – all of which are motorised.

Naturally such functionality necessitates a suite of motors, so how many do you think McMarky’s excavator has packed inside?

Nope. One.

Just a singular Power Functions L motor is able to drive all of the aforementioned functions, and – in many cases – multiple functions simultaneously. Which means not just no additional motors, but also no fancy programmable app-based remote control is required either, with the huge array of working functions instead controlled via a trio of red levers, each linked to the most complicated gearbox that we’ve ever seen.

It’s an outstanding example of mechanical engineering, and demonstrates that even if you don’t have the finances for a suite of motors, a third-party bluetooth battery, or access to a programmable app, immensely realistic motorised Technic creations are still within reach.

There’s more of McMarky’s seriously impressive uni-motor tracked excavator to see on Flickr and at the Eurobricks forum, where further images and a video of all those motorised functions in action can be found. Click the link above to be happy being single.

My Other Car’s a Huracan

The Lamborghini Huracan is boring. At least if the regularity at which YouTube ‘influencers’ (yuk) switch out of them into the next clickbait supercar is any indication. But no matter, because if you’re bored with your Huracan too (in LEGO Technic 42161 form), you can switch it up into this rather neat Technic truck, as previous bloggee mpj has done with his. Click the link above to see more of mpj’s 42161 B-Model on Brickshelf.


LEGO’s 42081 Volvo Autonomous Loader set thoroughly perplexed us when it was revealed a few years ago. It still does really, but tungpham of Eurobricks saw greater potential in the Technic oddity than we did, turning his 42081 set into this fantastic backhoe loader.

Looking considerably better than the set on which it’s based, tungpham’s 42081 B-Model includes a raising and tilting front bucket, in-cab steering and rear arm skewing control, stabilising legs, and a rotating driver’s seat.

It also features some of the finest presentation we’ve ever seen on a LEGO model, mimicking LEGO’s own box, catalogue and digital imagery with superb photography and editing.

Building instructions are available and there’s more to see of tungpham’s incredible alternate at the Eurobricks forum – click the link above for a B-Side that’s better than the Single.

Get Your Digs for Free

The internet is full of wonderful Lego models, many of which can be recreated at home thanks to readily available building instructions. For a fee.

Because one of life’s few certainties is that if something can be monitized, it will be.

But not today! Previous bloggee Thirdwigg is the hero we need, having created this excellent Technic tracked excavator, complete with a linear-actuator operated arm and bucket, a working piston engine, and a slewing superstructure, and he’s released building instructions for free.

The Lego Community could do we a few more members like Thirdwigg, and you can see more of his tracked excavator on Flickr. Click here to take a look, and here for a direct link to the free instructions.

My Other Tractor’s… er, Also a John Deere

The LEGO Technic 42157 John Deere 948L-II Skidder set is one that – after a look through our archives – we must’ve missed, what with it not being there. Still, we’ve never claimed to be competent, and the set does look rather good. Cue Dyens Creations of Flickr, who has repurposed the 42157 John Deere to create, well… another John Deere.

Dyens’ is the 9R, an XL wheeled tractor with up to 700bhp (there’s a tracked one too, which looks mad), outfitted in this case with a pneumatically operated bulldozer blade. There’s also articulated steering, a working piston engine, and a rear hitch with PTO, and there’s more to see of Dyens’ 42157 John Deere B-Model on Flickr.
