Watch this 650-hp Hennessey Jeep Grand Cherokee go from 0-60 in 3.9 seconds

Hennessey Performance Engineering has created an HPE650 package for the Jeep Grand Cherokee SRT fitted with the 6.4-liter Hemi engine. When it leaves the showroom floor it has 470 horsepower and gets from 0-60 miles per hour in 4.8 seconds. When it leaves Hennessey's garage floor after the upgrade it has 650 horsepower - 530 hp at the wheels, according to Hennessey - and gets to 60 mph in 3.9 seconds on its way to running the quarter-mile in 12.6 seconds.
There's more than just a Roots-type supercharger bolt-on, with ported cylinder heads and high-flow headers among the many changes made to the engine. You can watch this pre-2014 facelift silver model prove its spec sheet on the drag strip in the video below.

EV cost burden pushing automakers to their limits, says Stellantis' CEO Tavares

DETROIT — Stellantis CEO Carlos Tavares said external pressure on automakers to quickly shift to electric vehicles potentially threatens jobs and vehicle quality as producers struggle with EVs' higher costs. Governments and investors want car manufacturers to speed up the transition to electric vehicles, but the costs are "beyond the limits" of what the auto industry can sustain, Tavares said in an interview at the Reuters Next conference released Wednesday. "What has been decided is to impose on the automotive industry electrification that brings 50% additional costs against a conventional vehicle," he said. "There is no way we can transfer 50% of additional costs to the final consumer because most parts of the middle class will not be able to pay." Automakers could charge higher prices and sell fewer cars, or accept lower profit margins, Tavares said. Those paths both lead to cutbacks. Union leaders in Europe and North America have warned tens of thousands of jobs could be lost. Automakers need time for testing and ensuring that new technology will work, Tavares said. Pushing to speed that process up "is just going to be counter productive. It will lead to quality problems. It will lead to all sorts of problems," he said. Tavares said Stellantis is aiming to avoid cuts by boosting productivity at a pace far faster than industry norm. "Over the next five years we have to digest 10% productivity a year ... in an industry which is used to delivering 2 to 3% productivity" improvement, he said. "The future will tell us who is going to be able to digest this, and who will fail," Tavares said. "We are putting the industry on the limits." Electric vehicle costs are expected to fall, and analysts project that battery electric vehicles and combustion vehicles could reach cost parity during the second half of this decade. Like other automakers that earn profits from combustion vehicles, Stellantis is under pressure from both establishment automakers such as GM, Ford, VW and Hyundai, as well as start-ups such as Tesla and Rivian. The latter electric vehicle companies are far smaller in terms of vehicle sales and employment. But investors have given Tesla and Rivian higher market valuations than the owner of the highly profitable Jeep and Ram brands. That investor pressure is compounded by government policies aimed at cutting greenhouse gas emissions. The European Union, California and other jurisdictions have set goals to end sales of combustion vehicles by 2035.

FCA to appeal reduced judgment in Georgia Jeep case

FCA is appealing the $40 million verdict against it in a case in Georgia where a four-year-old boy died in a fire in a Jeep Grand Cherokee, according to The Detroit News. The jury originally awarded the child's family $150 million, but the judge decided to significantly to reduce the amount based on other precedents. The automaker has been considering further legal options since the decision was announced in July. The boy's death happened in 2012 when he was riding in a Grand Cherokee. The vehicle was rear-ended, and the fuel tank burst, causing a fire. This is the same issue that led to a recall of millions of the SUVs and a recent agreement with the US government from FCA to pay to get them fixed. In the original ruling, the jury said that the automaker was 99 percent responsible for the fatality and didn't adequately warn owners. It asked the company to pay $120 million for wrongful death and $30 million for his pain and suffering. FCA countered that the Jeeps met the safety standards of the time they were made. FCA requested that the jury's award be reduced in May calling the amount "grossly excessive." If the family didn't agree to a lower amount, the company also threatened to seek a new trial. Among the arguments was that $30 million was too much for the child's one minute of suffering. The parents did accept the judge's adjusted figure, though.
