Last month we have reported the existence of the Jeep Grand Cherokee SRT Hellcat with the supercharged 6.2L HEMI V8.

Recently, some other automobile medias claim that, they have heard from their “source” that the upcoming Grand Cherokee SRT Hellcat is able to reach a top speed of 200mph and run the 0-60 mph within 3 seconds (for example, this report).

While we cannot confirm whether the Grand Cherokee SRT Hellcat can reach 60mph in less than 3 seconds, we can definitely see in order to reach the speed of 200mph, how many horsepower the HEMI V8 engine need to make.

Using the same calculation procedure in our previous article (which calculates the output requirement for th...

For car consumers, some are focusing on interior spaces/convenience/daily drive practicability; some may prefer the fun-to-drive factor; and some may gauge their preferences on other aspects. This article is for those who want to get the quickest acceleration performance with lower budget.

10 years ago it is impossible to buy a new car which can accelerate to 60mph from a standstill within 5 seconds, and costs you less than $40k. However because of big advancements in engine technologies, it is now possible for auto makers to produce high-output cars with much less costs.

Are you impressed with the 707hp 2015 Dodge Challenger/Charger SRT Hellcat? Do you want a SUV with similar output? Now Jeep is going to help you with that.

According to our Chrysler insider, the company’s engineering team is working revising the 6.2L supercharged V8 engine, to make it suitable to sit inside the Grand Cherokee’s engine compartment. The project progress suggests an official debut in mid or late-2016 as the 2017 model.

Because FCA wants to use the nameplate of “SRT” solely for the Dodge brand, the future SRT/SRT Hellcat version of the Jeep Grand Cherokee may bear a new name called “Grand Cherokee Trackhawk”.

The final production version of the Grand Cheroke...

Since Dodge can do a SRT Hellcat trim for the Challenger, there is no technical issue that will prevent Dodge from putting the same powertrain in any of its rear-wheel-drive models.

So obviously we are not surprised that now Dodge has announced the 2015 Charger SRT Hellcat with the same 707hp engine. For more technical discussion of this supercharged 6.2L V8 engine, please see our article here. If you do not have time to go through the press release provided in the end of this article, here are some key highlights of this sedan monster.

– Supercharged 6.2L HEMI V8, 707hp, 650 lb-ft of torque
– ZF-sourced 8HP90 8-speed automatic transmission (no manual transmission offered...

Remember when Dodge officially announced the 2015 Challenger more than one month ago, it said the SRT model will come with “600-plus horsepower”.

Today it turns out the “600-plus” figure is way too conservative, because Dodge officailly released the final number: 707 hp, with 650 lb-ft of torque.

This is surprising, because 707 is excessively more than “600 plus”.

But this is not surprising too, because with the help of force induction you can achieve whatever level of output you want, theoretically speaking. Since Mercedes-Benz can pump out 360hp from the 2.0L displacement engine in the CLA45 AMG, why should not Dodge get 707hp from a displacement of 6...
