2020 Lexus RC F adds hardcore Track Edition and lots of carbon fiber

There's a shortage of high-performance naturally aspirated V8 engines in the United States these days. Fortunately, Lexus sees fit to keep its 5.0-liter V8 in production for the foreseeable future, updating it for 2020 and packaging it inside a revised RC F sports coupe. In its latest guise, the 5.0 spins out 472 horsepower and 395 pound-feet of torque, increases of 5 ponies and 6 lb-ft over the previous version. The RC F gets slightly revised styling for 2020 that includes minor updates to the headlights, taillights, and front and rear fascias. Underneath the skin, the coupe benefits from hollow half shafts, aluminum suspension bits, a lightened intake manifold, and a smaller air conditioning compressor all in a bid to save weight. Custom Michelin Pilot Sport 4S tires, a numerically higher rear axle ratio and the addition of a simple launch control system – press the brake, floor the gas, drop the brake – allows the 2020 RC F to hit 60 miles per hour in 4.2 seconds. 2020 Lexus RC F Track Edition View 30 Photos The biggest change for the RC F is the addition of a Track Edition for 2020. It's immediately recognizable by its massive carbon fiber rear wing and lower front spoiler. That fixed rear wing is lighter than the active spoiler of the standard RC F while simultaneously adding up to 58 more pounds of downforce and reducing drag. The hood, roof, rear-seat partition, and a bumper reinforcement are also made from carbon fiber. Other lightweighting bits include a titanium muffler and tailpipes, carbon ceramic brake rotors from Brembo, and 19-inch forged wheels from BBS. It all adds up to a 176-pound weight loss compared to the current RC F. Although the engine is unchanged from other 2020 RC F models, the weight reduction drops the 0-60 time down to 3.96 seconds. We don't yet have pricing for the 2020 RC F or the upgraded Track Edition, but Lexus says production will begin in the second quarter of 2019.

8 things you should know about the Lexus LC 500h powertrain

Lexus unveiled the LC 500h today in The Netherlands, and I got to take a look inside its new hybrid system. On one hand it seems like a box of magic – it combines two seemingly incompatible transmission types into one package. But that's also the ingenious simplicity of the thing. We don't have all of the details on how it all works yet, but here's a rundown of the high points.Efficient business in front, low-key party in the back. What makes it all work is the mullet of transmissions. For the new hybrid transmission, Lexus used the Toyota Hybrid Synergy Drive/Lexus Hybrid System – which consists of an e-CVT with a planetary gearset and two electric motors (one for charging the battery, the other for motivation and regen) – and grafted a conventional four-speed automatic onto the back. The two units actually coexist in one package, with the e-CVT making things efficient and the automatic expanding the capabilities. So at the low end, the system can deliver more torque, and the engine can also run at lower rpm on the highway. It's all thanks to those fixed gear ratios, and it's surprisingly simple.Except it's not that simple. This is where the virtual gear ratios come in. Like current Lexus hybrids, the system has ratios it can call up with the e-CVT. In this case, there are six virtual ratios to complement the four real physical ratios, for a total of 10 "gears" at the transmission's disposal. (Not coincidentally, the V8 LC 500 coupe has a 10-speed automatic.) One of the four fixed gears is always engaged when the car is moving, so the 10 ratios come about from combinations of what the e-CVT in front and the automatic in the back are doing. In other words, all 10 ratios are variations on the four fixed gear ratios, which means that all 10 gears could be considered virtual.It won't use all the gears all the time. In Eco mode, the car will start off on electric power and skip the first couple of "gears." When it's set to Sport or Sport +, the engine will be engaged from a stop and the transmission will select the lowest ratio. The sportier modes will also ignore the top couple of gear ratios.It can drive faster with the engine off. In a Lexus GS 450h with the Lexus Hybrid System, for example, at speeds above 62 mph or so the engine has to start up. This is because something needs to take up some slack from the battery-charging motor-generator or else it will start spinning too quickly.
