Nuclear-powered concept cars from the Atomic Age

In the 1950s and early 60s, the dawn of nuclear power was supposed to lead to a limitless consumer culture, a world of flying cars and autonomous kitchens all powered by clean energy. In Europe, it offered the then-limping continent a cheap, inexhaustible supply of power after years of rationing and infrastructure damage brought on by two World Wars.
The development of nuclear-powered submarines and ships during the 1940s and 50s led car designers to begin conceptualizing atomic vehicles. Fueled by a consistent reaction, these cars would theoretically produce no harmful byproducts and rarely need to refuel. Combining these vehicles with the new interstate system presented amazing potential for American mobility.
But the fantasy soon faded. There were just too many problems with the realities of nuclear power. For starters, the powerplant would be too small to attain a reaction unless the car contained weapons-grade atomic materials. Doing so would mean every fender-bender could result in a minor nuclear holocaust. Additionally, many of the designers assumed a lightweight shielding material or even forcefields would eventually be invented (they still haven't) to protect passengers from harmful radiation. Analyses of the atomic car concept at the time determined that a 50-ton lead barrier would be necessary to prevent exposure.

2023 Ford F-150 Raptor R vs. 2022 Ram TRX | By the numbers

Ford has responded to the Ram 1500 TRX with its own supercharged supertruck: the brand-new 2023 Ford F-150 Raptor R. Ford may be late to the party, but fans can rest assured that its 5.2-liter supercharged V8 is ready to throw down, packing 700 horsepower in a leaner, more-focused package. You can read all about the new Raptor R in our debut write-up, but if you're curious how it stacks up to the TRX by some of its key metrics, you're in the right place. Let's get started.  Performance Let's go ahead and get this one out of the way. Both of these trucks offer blistering performance figures, but a quick glance at the specs suggests a clear winner. Both the Ford and Ram are half-ton crew cab pickups powered by supercharged V8s, but how that package comes together differs pretty significantly between the two.  2023 Ford F-150 Raptor R Engine: 5.2-liter supercharged DOHC V8 Power: 700 horsepower Torque: 640 pound-feet Suspension: Independent double-wishbone (front); five-link coil with Panhard rod (rear); continuously variable active Fox dampers (both) Curb Weight: 5,950 pounds 2022 Ram 1500 TRX Engine: 6.2-liter supercharged OHV V8 Power: 702 horsepower Torque: 650 pound-feet Suspension: Independent double-wishbone (front); five-link coil with track bar (rear); active Bilstein dampers (both) Curb Weight: 6,395 pounds Conclusion It was looking good for the TRX right up until the end there. Ram has the edge in total power and torque — just barely — but that advantage disappears when you consider the TRX's extra heft. 400 pounds may not seem like the end of the world in the context of these trucks, but weight plays a roll in all aspects of performance. This looks like a home run for the Blue Oval.  Off-road Raptor was the default half-ton performance truck for many years, but with OEMs getting ever more serious about building full-size pickups that can take a beating off-pavement, Ford has leaned harder into the Raptor's high-speed performance. Ram's approach was similar, only with more power — until now, that is. But there's more to off-roading than blasting across the desert.

Chevy Traverse, Hyundai Santa Fe revealed; Buick Envista, BMW M4 CSL driven | Autoblog Podcast #790

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor John Beltz Snyder. After some banter, including the discussion of an excellent tomato sauce recipe, they get into car reviews. Greg has been driving the Mercedes-AMG GLE 53, while John has been testing the BMW M4 CSL and Buick's new Envista crossover. There's lots of interesting news this week. Chevy revealed the 2024 Traverse with new looks, a new engine and on off-road(ish) trim. Hyundai gave us a glimpse at the wild styling of the next Santa Fe. Dodge might bring back the Stealth nameplate as an SUV, and that has implications for the Durango as well. Ford, after repeatedly raising prices, has turned around and significantly discounted the F-150 Lightning across all trims. The first Tesla Cybertruck has rolled off the line as a pre-production prototype. Finally, we reach in to the mailbag and help a listener decide what to do with cars for himself and his kids in this week's Spend My Money segment.
