BMW M4 vs. Lexus RC F in Head 2 Head sports coupe showdown

It's the showdown everyone's been looking forward to, the East versus West grudge match of the year. We're talking, of course, about the BMW M4 versus the Lexus RC F.
Although BMW uses a twin-turbo straight-six and the Lexus uses a free-breathing V8, the two are pretty closely matched on paper: a luxury coupe with over 400 horsepower channeled to the rear wheels.
The BMW has been doing these cars for longer, and the M4 boasts a higher power-to-weight ratio. But then the RC F has more power - and without forced induction to break up the rev range. So which is the better luxury muscle coupe? Watch the latest episode of Motor Trend Head 2 Head to find out.

Why is there a huge bulge in 2021 Lexus IS 300 AWD's driver footwell? We explain

After an initial turn a few weeks ago for the 2021 Lexus IS first drive review, the revised luxury sedan has returned to the Autoblog garage for a second look. This middle-of-the-road IS 300 AWD pairs a 260-horsepower V6 with a six-speed automatic transmission and four driven wheels, and frankly it's the least interesting way to spec out the redesigned sedan. While there are cars in this segment designed to get a performance boost from their all-wheel-drive systems even in dry conditions, the IS isn't one of them. Adding insult to injury, you get stuck with a cramped driver-side footwell care of the engineering shenanigans that went into making this system possible.  While we've mentioned this particular compromise before, we rarely touch on the reasons why it exists in the first place. The fundamentals are fairly obvious; the standard IS utilizes a longitudinal, rear-wheel-drive powertrain. As is typical with this configuration, the transmission sits in a tunnel beneath the center console. This arrangement works just fine, provided you don't need to power the front wheels.  To do so in a traditional car like the IS requires a literal end-around maneuver involving the engine and transmission, which we've diagrammed for you below care of MSPaint. This is a bit simplified for the sake of this write-up, and it should be noted that this is not the only way to implement AWD in an inherently RWD platform, but it illustrates how the power for the front axle (red) and rear axle (blue) flows from the transmission to the drive wheels. To get juice flowing to the front axle, Lexus had to add a parallel output shaft, exiting the transmission from the front with enough clearance for the bell housing and engine, which sits between the transmission and the front differential. This requires quite a bit of lateral reach, meaning the housing has to extend much farther out than usual to accommodate it (yellow arrow). As a result, the all-wheel-drive transmission looks a lot like a sci-fi gun with a chunky drum magazine hanging off the side of it. The hump (above right) in the footwell is there to clear this protrusion. This basic configuration isn't unique to Lexus. In fact, if you look at a BMW xDrive cutaway, it's similar. So, why no "hump" in other cars? There are multiple factors, but to boil it down to what is most relevant, it's a combination of the resulting shape of the Lexus transmission housing and the size of the IS chassis.

Google self-driving car badly damaged in accident but wasn't at fault

A self-driving Lexus RX 450h hybrid sport utility vehicle owned and operated by Google was involved in an accident in Mountain View, California, on Friday afternoon. Nobody was injured, though there was an occupant inside the Lexus at the time of the crash. Initial reports indicate Google's autonomous vehicle was not at fault. The accident happened when another driver in a commercial van ran a red light and hit the passenger side of the autonomous vehicle. Google confirmed that the vehicle was piloting itself at the time of the accident. When it became obvious a collision was imminent, the human driver applied the brakes, but it was too late. The car sustained significant damage in the crash and had to be towed away on a flatbed trailer. This isn't the first time one of Google's self-driving vehicles was involved in an accident, but it does appear to be the first time one of the tech giant's cars sustained serious damage. In a statement to 9to5Google.com, Google said, "Thousands of crashes happen everyday on US roads, and red-light running is the leading cause of urban crashes in the US. Human error plays a role in 94% of these crashes, which is why we're developing fully self-driving technology to make our roads safer." The United States Department of Transportation earlier this week outlined a set of 15 safety assessment objectives for autonomous vehicle manufacturers to meet. The DOT said "automated vehicles hold enormous potential benefits for safety, mobility and sustainability."
