Watch a Cayenne Turbo S, Range Rover SVR, and Cherokee SRT drag race

We live in a weird world where high-performance SUVs could win a 60-mile-per-hour sprint against sports cars from just a few years ago. Here, Top Gear sets up a three-way drag race against the Porsche Cayenne Turbo S, Land Rover Range Rover Sport SVR, and Jeep Grand Cherokee SRT, and the results show just how quickly these high-riding models can cross the quarter mile. The Cherokee SRT is the patriotic choice among the three, but it's down on power in this fight. Meanwhile, the Range Rover's menacing growl sounds the best, and the Cayenne Turbo S has the most horsepower. You'll have to watch the video to see which SUV will win this battle. Related Video:

Ram, Jeep redesigns on hold, Alfa Romeo models may come sooner

Last summer, FCA outlined an ambitious five-year plan that sketched out the company's product intentions for each of its brands through the end of 2018. However, even the best strategies sometimes need tweaking. According to Reuters after speaking with unnamed people at auto suppliers, FCA is now possibly delaying at least a dozen projects in North America for a variety of reasons. From vehicle to vehicle, these postponements allegedly last anywhere from just a few months to over a year. The sources from the suppliers claim that in some cases these tweaks are for engineering and design changes. The next-gen Ram 1500 reportedly has among the shorter delays and is being pushed from mid-2017 to November 2017, according to Reuters. Also, the much-discussed future Jeep Wrangler is allegedly moving a little later to July 2017. Among the vehicles purportedly seeing longer delays, the next-gen Grand Cherokee could get pushed back about a year to 2018. That then forces the launch of the three-row, luxury Grand Wagoneer to be even further away. Jeep's upcoming C-segment CUV and the all-new Chrysler 300, Dodge Charger, and Challenger might also see postponements. The one brand allegedly seeing an accelerated plan is Alfa Romeo. Without going into detail, the sources from these suppliers claim that the Italian automaker is getting even more vehicles for its lineup and could get them even faster than planned. "Those plans need to be flexible and fluid, with the potential to add some vehicles, pull some forward and extend the life cycle of others," FCA said to Reuters about all of these allegations. "We look at these programs on a vehicle-by-vehicle basis." Investment in the auto industry has been a major topic for FCA CEO Sergio Marchionne as of late. He believes consolidation is necessary so that companies aren't burning money on the same projects.
