Mazda’s adding a new clean diesel to the ever popular Mazda 6 family sedan. The new CRTD is based on the standard 2.0L petrol, but only gains 6 kg despite turbocharging and a bevy of improvements. The 136KW(185HP), 400nm motor promises to be an exercise in torque steer for the light sedan, but owners will be smiling with an impressive fuel economy of 5.6L/100kms. The new CRTD will be sent first to Europe, and it remains to be seen if motor will arrive in Australia.
Mazda Develops new Clean Diesel Engine with Improved Output and Environmental Performance
Mazda Motor Corporation has developed a greatly improved clean diesel engine that offers output and environmental performance comparable to a gasoline engine. It will be progressively introduced to markets around the world, beginning in Europe in 2009.
The newly developed MZR-CD 2.2 clean diesel engine has a displacement ten percent greater than Mazda’s current MZR-CD 2.0-liter diesel, and achieves top class torque of 400 Newton meters. Improved fuel injectors and a lower compression ratio contribute to its enhanced fuel efficiency. Additionally, the engine’s diesel particulate filter (DPF) features a Mazda-developed world-first catalyst activation mechanism that enhances the removal of particulate matter (soot) from the exhaust gases. The new catalytic combustion treatment process enables the DPF to burn off particulate matter approximately 60 percent faster than current systems. Due to this technical advancement, the MZR-CD 2.2 is clean enough to qualify for the Euro 5 emissions standards. (This is based on a Mazda in-house assessment.)
Furthermore, the addition of a dual balance shaft and a more rigid engine block has resulted in a significant reduction in engine vibration, and helps achieve extremely quiet operation.
Main features of the new MZR-CD 2.2 clean diesel engine
-2.2-liter DOHC common rail turbo diesel engine
-Top class high performance clean diesel engine:
-136 kW/185PS maximum power output
-400 Nm maximum torque
-Excellent fuel economy of 5.6 L/100 km
-Greatly improved quietness
Newly developed diesel particulate filter (DPF)
Mazda’s new clean diesel engine has a high thermal resistance diesel particulate filter (DPF) with a catalyst that optimizes the combustion of soot in the exhaust. The catalyst features a proprietary world-first activation mechanism. Combined with more precise engine control, this mechanism doubles the interval between DPF regeneration cycles, and reduces the time to complete the regeneration process to a third of the time necessary for conventional systems.
Catalysts use the oxygen contained in exhaust gases to burn off particulate matter. In order to initiate combustion, the temperature of the exhaust gas must be increased. This requires additional fuel, which adversely affects overall fuel economy.
The ceramic base material in Mazda’s unique catalyst has a molecular structure that enables the easy movement of oxygen stored within it. This extra oxygen can be supplied as required to significantly increase the rate of particulate matter combustion, effectively the DPF regeneration speed.
As a result, the new catalyst mechanism reduces the amount of fuel required to burn off the particulates (soot). This improves the overall fuel economy, and results in lower CO2 emissions and cleaner exhaust gases.

Rumors have been flying about a new performance oriented Toyota sports car hitting the performance scene for a considerable time now, from an AE86 revival to a new Supra, but perhaps no one expected news that these shadowy rumors would coalesce into the forgotten Celica GT-4.

The last model Celica. Will we see styling cues from this?
But perhaps even more surprising is the rumor that the car will be engineered to a large degree by Subaru. In November Toyota confirmed rumours of a new sports car and Celica replacement, with the sports car being a collaboration between Subaru and Toyota, and now it seems the car is the performance model of the Celica line. However, the new car will not come with a Toyota bred turbo four in the tradition of the (somewhat) underpowered motor of the old model - instead it’s going to be carrying a Subaru Boxer turbo, most recently seen in the all grown up Subaru Impreza WRX STi.
The new model is said to come in two distinct performance variants. First, the base ‘GT’, packing a front engined, RWD drivetrain and naturally aspirated 2.0L 4 cylinder Boxer (most likely from the Impreza RX), designed to slide in under the $20,000 bracket. Secondly the full fat GT-4, which carries the new JDM STi’s 224KW (300HP) Boxer turbo and AWD system standard, with Motor Trend claiming the engine will be closer to the cars firewall in order to facilitate the installation of in-wheel electric motors to help with traction.
The GT and GT-4 will be built in in coupe and three-door hatch variants, but no five door variants because of Toyota and Subaru not wanting to compete in the Impreza’s arena, which is rather tongue in cheek considering this new car will inevitably be seen as either a Impreza in Toyota clothing, or as direct competition by tuners. This begs the question then; will the new GT-4 be a real contender in the hotly contested price for performance bracket? Will the Toyota be lighter, faster, and more capable than the new STi? Would Subaru shoot themselves in the foot, and does it matter considering Toyota’s widening stake in Subaru?
Does this mean Subaru will become more and more the performance arm of Toyota? Time will tell, but we certainly hope not.

It turns out that Mitsubishi Europe has quietly released details on the Ralliart Lancer.
Mitsubishi doesn�t state whether the Ralliart will be based on the 4door Lancer or the upcoming 5door hatch, however Carscoop states the USDM Ralliart will be based on 4 door lancer sedan, whereas Europe will get the 5 door hatch. Since Australia classically gets the closest equivalent on the JDM, we can expect to see the 4 door on our roads.
The Ralliart is expected to run a detuned 177KW, 240PS version of the EVO X 2.0L, dual valve VVT turbo 4 cylinder. Coupled to this is the magnificent 6-speed Twin Clutch SST transmission, and AWD with Active Centre Differential and Active Yaw Control.
The final form of the Ralliart in Australia is unknown, but given the competition between Subaru and Mitsubishi in this segment we can expect the Ralliart to slot firmly into position against the standard Subaru Impreza WRX - leaving the Evo X to tackle the WRX STi.
Being somewhat given to fantasy here at IJ, we’d love to see that Sportback concept reproduced in full for the hatchback. Given the standard new Lancer is being hailed as a runaway success for Mitsu, a return of the Ralliart Lancer is sure to be nothing less than a added cream in Mitsu’s profits in an age of high demand for fast, small, fuel efficient cars.

The way it should have been? We’ll leave that decision up to you and the ever vocal purists. But nothing can take away from the pure awesomeness of the Skyline GT-R’s donk in that slick, black 300zx body.

We love the Toyota Supra, particularly the MKIV’s awesome curves and potent 2JZ-GTE forged twin turbocharged inline 6 cylinder. So we’d thought we’d celebrate by rounding up our top 10 favourite online videos of the Mark IV Supra in all it’s glorious RWD action.
