Lexus has introduced its first diesel model—a version of the just-introduced next-generation IS, using the same 2.2-liter all-aluminum engine and aftertreatment technology as in the new Toyota Avensis. (Earlier post).
The new diesel IS, rolled out at the Geneva Motor Show, is targeted for the European market.
The specifications for the Lexus and Toyota engines are the same. The new 2.2-liter Lexus diesel is also equipped with “Lexus Clean Diesel Technology”—the Lexus analog to Toyota’s D-CAT.
Both use the Diesel Particulate NOx Reduction (DPNR) 4-way catalytic converter as the foundation for the emissions improvements.
As noted in the comments on the earlier post on the Avensis, some automakers are challenging Toyota’s claims about the capability of its DPNR system.
