Lexus has trademarked “TX 550h+” in the United States and while we haven’t seen the new full-size, three-row crossover just yet, we can make some guesses about powertrains based on this information.
Previously, Lexus trademarked “TX 350,” likely coming with the same 2.4L turbocharged four cylinder engine as the new NX 350, and “TX 500h,” speculated to use that same 2.4L turbocharged four cylinder mated to a hybrid system.
A new TX 550h+ would likely sit atop the TX pecking order, possibly using the 2.4L turbocharged four cylinder engine mated to a larger battery pack that provides electric-only driving options, similar to the NX 450h+. One of the upsides of that powertrain would be more power as well, and with a “550” designation, it seems logical to assume this powertrain could return 350-400 horsepower in final form.
We continue to watch the development of the TX and will share updates.
