The Best Luxury Cars in 2011
by James Bleeker
The best luxury cars by the 2011 Auto Reliability Grade Point Average (GPA) are:
Honda's Acura RL, an
all-wheel-drive, V6 luxury sedan with a 2011 Auto Reliability GPA of
3.85 over a 6-year auto reliability data history,
Toyota's Lexus ES,
a luxury sedan with a 2011 Auto Reliability GPA of 3.69 over a 10-year auto reliability data history,
Toyota's Lexus LS, a luxury sedan with a 2011
Auto Reliability GPA of 3.63 over a 10-year auto reliability data history.
Toyota Motor Corporation and Honda Motor Company account for
all three of 2011's best luxury sedans.
These luxury cars are among the Top 30
automobiles offering 3 or
more model years of reliability data in 2011.
The method of computation of the GPAs is probably familiar to nearly
every college, technical school, and high school student. A Grade Point of
4.00 (that is, an A) is given to a Consumer Reports "Much Better
Than Average" rating, a GP of 3.00 (that is, a B) is given to a
CR "Better Than Average" rating, a GP of 2.00 (that is, a C) to
an "Average" rating, a GP of 1.00 (that is, a D) to a "Worse
Than Average" rating, and a GP of 0.00 (that is, an F) to a
"Much Worse Than Average" rating. A Grade Point Average (GPA) is
an average of the Grade Points and is computed using Microsoft's
Average(a:b,[c:d],...) function. The above GPAs are the Average
GPAs given in the table "The Updated 2011 Motor Vehicle Reliability
Grade Point Averages (GPAs) and Grades with
Reliability GPAs for Four 4-Year Age Ranges and
an Overall Average Reliability GPA" on the
Reliability Grade Point Averages and Grades page.
The sources for Consumer Reports' ratings are the reliability
tables in (1) the April 2011 issue of Consumer Reports, (2) Consumer
Reports New Car Buying Guide: 2011, and (3) Consumer Reports Used
Car Buying Guide: 2011.
Consumer Reports defines reliability as the infrequency
of reported serious problems.
