Lexus RC F is a predatory sport coupe with a 450-horsepower beating heart

Take a look at that face. We can't be the only ones who see an automotive Predator staring back, right? Certainly, the Lexus RC F Coupe boasts a visually striking design that some are going to love and others are going to hate, but we can at least appreciate that it's aggressive, especially compared to the standard RC Coupe that we saw at the Tokyo Motor Show. And with good reason - there's a 5.0-liter V8 engine sitting under that massively domed hood with "more than 450 horsepower," along with a newly calibrated eight-speed automatic gearbox.
Interestingly, Lexus has tuned the RC F's engine to run on an Atkinson cycle under most circumstances, while it switches to the more typical Otto cycle when more power is required, presumably using some sort of advanced variable valve timing technology. Helping put that power to the ground with all those ponies wreaking havoc underhood is a torque vectoring differential, a first from Lexus.
Also involved in keeping the RC F planted is an aero package that includes wings and ducts galore. The headline bit is an active rear wing that deploys at 50 miles per hour and retracts back into the deck when the car drops back to 25 mph. A clear-coated carbon fiber roof can optionally join that carbon rear wing. There are apparently going to be three 19-inch wheel options, including the ones you see in our live image gallery above.

2014 Lexus IS brings boldest design yet to entry-level luxury

Lexus is evidently dead serious about removing some of the starch from its collar, as evidenced by the boldly styled new IS sedan just unveiled here at the Detroit Auto Show. We didn't know what to make of Lexus' entry-level sport sedan when we first saw images of it earlier this week. Dominated by the gaping maw of a spindle grille and flanked by headlamps with Nike swoosh daytime running lamps, the photos showed a distinctive (if not completely cohesive) design. Having now seen the design in the metal, we have to admit it comes together better than it does on screen.
The new model will feature both rear- and all-wheel drive models in both 2.5-liter V6 (IS250) and 3.5-liter V6 (IS350) trims. Lexus also showed an IS300h hybrid model at the reveal, but it is earmarked for Lexus' home market of Japan, along with Europe and other markets. No word yet on why the model probably won't be sold here in North America, but our AutoblogGreen compatriots are looking into it.
Aside from its bold new look front and rear, the IS carries forward a lot of the ideas seen in other newer Lexus models, namely the GS. Hidden beneath the IS' sheetmetal is the multilink rear suspension from the GS, along with its electric power steering setup. The new IS rides atop a three-inch longer wheelbase for better rear seat room, but during our brief time sitting in the car at the press conference melee, it still didn't feel terribly roomy (it rarely does in this class). At least the seatbacks fold 60/40 for the first time for additional utility.

Lexus IS, new and old, and LFA to make splash at SEMA

Lexus has announced its Specialty Equipment Market Association (SEMA) show cars: a group of eight Lexus IS sedans spanning all three generations, and a 2012 LFA supercar. One of the show cars, a custom 2014 Lexus IS 350 F Sport, is a creation penned by IS fan Rob Evans, the winner of a contest to design a Lexus SEMA show car.
The standouts in the group of Lexus IS show cars, in no particular order, are a 700-horsepower 2014 Lexus IS 340 (it has a heavily modified Toyota Supra inline six swapped in, which is stroked out to 3.4 liters, hence the nomenclature change) by Philip Case and a supercharged 2004 Lexus IS 300 by Maricar Cortez. Both cars prove that oldies can be goodies - the venerable Supra 2JZTE engine, which ceased production over a decade ago, lives on in a 2014 platform, and the 2004 IS 300 gets a supercharger and remains relevant through the use of electronics, such as a back-up radar sensor, upgraded headlights and more.
Of course, the LFA by Guy S. De Alwis will be a stand out on its own, but unfortunately Lexus only provided us with a couple pictures that don't do it justice. We'll have to take a closer look at it on the show floor. Same goes for the IS penned by contest-winner Rob Evans, of which only a rendering was provided.
